Speaker 2 (00:10):
Break repairs are such a critical part of water repair,
and it seems like in the day and age of computerization,
breaks are still something that everybody does and whether you're
a professional or a do it yourselfer, you need to
do it correctly. I mean, let's face it, you know
that old adage, what's stopping you and they talk about
(00:32):
your breaks? Well, we've gathered up Scott Brownstein. He is
the senior technical manager over there at CRC Industries. Scott,
I said that name right right, yes, and he's going
to help us today talking about some of the important
things about break maintenance and repair. Scott, Welcome to the
Car Doctor.
Speaker 3 (00:52):
Sir, thank you for having me. It's a pleasure to
be here.
Speaker 1 (00:55):
You're very welcome. You know.
Speaker 2 (00:58):
I always think about there was an ad in the seventies,
maybe the eighties, early eighties where they showed the difference
of doing breaks, and I think it might have been
CRC that actually had the print dead where they showed
a picture of two mechanics working on cars and one,
you know, was doing a perfectly, you know, very nice
clean brake repair. The rotors were clean, and the other
(01:19):
guy had grease all over the place and you know,
there her fingerprints on the brake pads, and you know,
and they stressed the importance of cleanliness. That's that's fifty
years ago. Cleanliness on breaks. It's just so important, you know,
state the obvious, Scott tell us, why let's start here.
Speaker 3 (01:35):
Absolutely, you do not want any grease, grime, oil on
any of the friction material surfaces, the front of the
brake pads where it contacts the rotor, the drums, the shoes,
any of those contaminants. When you do your first initial
bed in, you can actually just ruin a set of
(01:56):
pads and ruggers just by burning those oils into it.
And it's so important to use a good break parts
cleaner to make sure all those areas are spotless during
your assembly.
Speaker 2 (02:08):
Can we talk about that for a quick second.
Speaker 1 (02:10):
You used a term bed in.
Speaker 2 (02:11):
Boy, I haven't heard that in a million years, but
it's absolutely spot on. What is bed in? Explain that
real quick.
Speaker 3 (02:19):
So when you have a brand new set of pads
and rotors, just it's a relationship. So you want those
two materials to wear in together into each other and
you go out and most people don't read the instructions
anymore nowadays, but most the brake pads have a bet
in procedure where you go out and you do so
(02:39):
many stops stop to zero, but from fifty down to twenty,
and you repeat that a handful of time. So you
put some heat into the brakes, you lay them the
cooled off, and you actually get those two friction services
to marry to one another.
Speaker 2 (02:54):
Now, CRC and I've been using CRC products full disclosure
here since the late seventies. I remember red, white, and
black cans in all of my repair base. CRC offers
a non chlorinated break clean That was a big deal
when that came out. So why would someone want to
use that? What's the importance of a non chlorinated break cleaner?
Speaker 3 (03:17):
Absolutely? So it comes down to government regulations and all
the different states have different rules for what chemicals you
can put into products. So some states you're allowed to
use stronger chemicals, other states you have to use weaker chemicals.
And that's really due to VOC's and small contributing compounds,
(03:39):
so on and so forth, and.
Speaker 2 (03:41):
It's so it's a little better for you to use
a non chlorinated break cleaner.
Speaker 1 (03:45):
Is that a misstatement?
Speaker 2 (03:45):
Is that a childhood myth?
Speaker 3 (03:48):
No, it's a step in the right direction because chlorinated
products too, they can contaminate waste oil and things like that,
and certain states even ban the use of chlorinated products.
Son or you can get in every state depending on
what are the government restrictions for it.
Speaker 2 (04:05):
What leads to break noise? And let me preface that question,
because this is a common complaint, right, I just did
breaks and they're noisy? Did I use too much break clean?
You know how many times a week I get that question?
And that's not really it. Break clean is actually the
safest thing you can use on a break repair. The
guys using carburetor cleaner or fuel injection cleaner on the
(04:27):
roads because they don't want to buy break clean, they're
doing it wrong.
Speaker 1 (04:29):
Aren't they.
Speaker 3 (04:31):
Absolutely Some of those products could have oils and other
contaminants and them break parts cleaner is the right tool
for the job because it's going to leave no ris
to do behind. Instruments dry really quickly. Now. Break noise, though,
can be contributed to other things I've in the past,
in my past life when I was a dealership technician,
I've had a couple comebacks as well. You know, no
(04:55):
one's protected from having a comeback once in a blue moon.
We try to avoid it, and break squeal is very possible,
and what can happen sometimes is you actually get chatter
and movement of the brake pad against the caliber, and
it causes a frequency vibration. So there's a product out
there we may call this break quiet, and it's actually
(05:17):
like a tacky gel once it sets up. So you
put it on the back of the brake pads, the
non friction side, and you're only going to draw all
the day out in a little squeeze. But all we
sell it in just where the caliber is going to
contact that, let it sit for five minutes, tack up,
put the car back together, and that is actually going
to dampen and absorb and prevent that frequency vibration from
(05:37):
a reoccurring, and you have nice quiet breaks again.
Speaker 2 (05:41):
You know, I always, I always equate that frequency vibration,
and that's that's a great way to put it. I
always explain it to people at the counter that the
reason we use this break quiet, the little orange bottle
is it It's like remember at your high school prom
when you were bored and you don't know what to say
to your date and the water glass was half full
and you're in your finger around the top and if
you did it enough times and fast enough, it would
(06:02):
start to distort and make sound. And you thought it
was the cool thing to do at seventeen. And that's
sort of what that's sort of what the brakes are doing.
They're they're finding that frequency point and it just becomes
a distortion and you're hearing it in the brake squeal.
And that's what the disc break quiet is doing, right,
It's absorbing that and keeping the pad from shifting around
so it doesn't chatter. So to speak exactly, carbon, I
(06:26):
want to I want to jump around a little bit
and I want to you know, since I have you,
I want to talk a little bit about, you know,
fuel system cleaning if I can real quick, I want
to jump into that. You know, carbon is a big
issue on today's engines. And I didn't realize you were
dealer tech, so I'm sure you've got some dealer tech stories.
Speaker 1 (06:43):
About the cars you saw.
Speaker 2 (06:45):
Carbon becomes a problem, and you know today's vehicles everything
is GDI right, gasoline direct injection, So everybody wants to
know fuel system cleaning and how to go about it,
and why is carbon such a problem.
Speaker 1 (07:02):
Today, can you tell us absolutely?
Speaker 3 (07:05):
So with gasleen direct injection, we're able to get better
fuel economy, better performance in a smaller displacement engine. But
we're bringing back an old school problem in these prank
case vapors come back around through the PCV system. We're
having these oil vapor deposits land on the intake valves
(07:27):
that are hot, and they're immediately carbonizing up because the
intake manifolds plastics of the oil is not sticking there.
It's going to stick onto the metal down the path
and we're not having fuel injectors up in the port
anymore washing over and clean that carbon off the valve,
so they're they're packing up, it gets gummy and then
(07:48):
it starts causing all these other drivability issues. So cleaning
and spraying an air induction cleaning surf product that we
one of the ones that we make, goes through the
throttle body and it's going to land and slowly break
down and emulsify that carbon and allow it to come
off these intake valves. Another thing is is that now
(08:11):
back in the day, you used to use a fuel
tank additive which would clean the carbon off these valves.
Even though it doesn't work on the intake valves. Today,
it's still really important to do that because with these
direct injection engines, we're using the fuel to cool down
the cylinder before the next combustion event. And if these
(08:32):
little tiny pindles on the injectors they get clogged up
with carbon and then you're not getting a complete cone
animized spray across the cylinder evenly, which could lead to
hot spots and predetonation. So using a good fuel injection
cleaner is still important today, even on today's vehicles.
Speaker 2 (08:52):
You make a good point, Scott. And when we come back,
I want to talk about using tank cleaner and its
effects on catalytic converters. All right, let's pull over, take
a pause. I'm ronning any in the car. Doctor. I'm
here with Scott Brownstein of CRC Industries, and we'll both
return right after this.
Speaker 1 (09:06):
Don't go away.
Speaker 3 (09:25):
A thousand dollars card ain't worth nothing.
Speaker 1 (09:42):
We are back.
Speaker 2 (09:43):
And before we pulled away and took the pause, Scott
Brownstein and I we were talking. Scott's from the CRC Industries.
He's the senior technical manager over there.
Speaker 1 (09:52):
Scott.
Speaker 2 (09:52):
The question that was coming up. We were talking about
fuel tank at it is.
Speaker 1 (09:56):
Now.
Speaker 2 (09:56):
This is a conversation that started about breaks, and I
purposely you're blindsided you hearing I'm sorry we're talking fuel
systems all of a sudden, because I know CRC's history
with fuel systems too. Tank editives is where the conversation
was headed. There's a reason beyond the engine why we
put a tank editive and a fuel tank system cleaner,
because that helps the catalytic converter too.
Speaker 1 (10:17):
Doesn't it.
Speaker 3 (10:19):
Absolutely so, anything that is coming out of the engine
has to pass through that catalytic converter, and there are
things that we can do to help clean the catalytic converter,
promote a healthy catalytic converter, and make sure that it
gets the full designed life out of it. So it's
not just even just a passing your emissions test. And
(10:41):
that's what most people related to is, Oh, it's that
time of the year. I have to make sure I
do this. You should be doing this a couple times
a year so you don't get to that point of oh, BOYD,
now that check engine lights on. I have that forts one,
that four point thirty code, and I got to go
for my emissions testing in two weeks. You know, and
then there's that panic that sets it.
Speaker 2 (11:03):
So that fuel system cleaner, you know, and I'm sure
there's some proprietary blends of stuff in there that CRC uses.
They it basically it attacks the lack of a better
way to say it, and correct me if I'm wrong,
but it attacks the crud and the catalytic converter and helps.
Speaker 1 (11:19):
Keep the the the you know.
Speaker 2 (11:22):
The structure of the cat active so it stays clean
and it's efficient and it does its job correct. Yes, exactly,
so vehicle emissions testing because you brought it up, so
you know, doing tank additive is good preventative maintenance, and
that's also part of that Tank editive is also part
of the CRC GDI service pack if we're doing a
(11:44):
fuel system cleaning, which is where that conversation started, right, Yes,
so that tank additive part of that pack, and I'm
sure it's available separately, does a good job cleaning the cat.
But then there's something else you guys have which I've
always wanted to ask somebody from CRC about. You've got
something called guarantee to pass.
Speaker 3 (12:00):
Guaranteed to pass, so that is specifically formulate for cleaning
the crucial emissions components that the fuel touches, including the
Catalai converter, and with the cost of Calaie converters today
in the labor to replace them, I always explain to
people this is the best thing to try before you
actually have to spend that amount of money to replace
the Catlee converter. This is using Pea technology, so polyether imine,
(12:25):
and that's what's attaching and breaking down the carbon, and
that's what's getting all the tough crowd out of the engine.
Speaker 2 (12:33):
So suffice it to say, if anybody out there has
a vehicle that's burning oil, and I love I always
love these questions, and true to form, they won't make
the connection until I pointed out. But if you've got
a vehicle out there that's burning oil, a court in
one thousand miles, a court in fifteen hundred miles, using
(12:55):
a tank additive, using something like like guaranteed to pass,
all right, you know, fuel system cleaner is going to
help keep that cat healthy because that cat is not
only digesting exhaust, it's digesting oil, which is a carbon
based substance, right slogging up the cat over a period
(13:18):
of time.
Speaker 3 (13:20):
Absolutely, and that is something that you want to make
sure you get that engine fixed and rectified if one
of those rings are sticking or something's happening, so it'll
it'll help push you along. But in some cases, too
much oil or even too much fuel for that matter,
dumping down a cafe like a stuck fuel injector, that's
(13:40):
just going to kill the cat pretty quickly. And you know,
no product on the market's going to help bring that
cataly converter back.
Speaker 2 (13:49):
Right other than a new catalytic converter, which can range
in price anywhere from eight hundred to three thousand dollars
plus labor. So it becomes it becomes a chore, yep,
and a pain expense. In our closing minute here, Scott,
you know I want to switch gears one last time.
QD Contact Cleaner. That CRC makes you know, there's more
(14:11):
electronics than ever and I love that QD Contact cleaner.
I've got cans of it around the shop. Why can't
I just why can't I just use break clean?
Speaker 3 (14:24):
You know, you could use a brake cleaner or a
carb cleaner and to become a more costly expense very quickly,
because now you have to replace that part. Most of
these parts are in all these sensors that are encased
in plastic, whether you're cleaning corrosion now that the connectors,
or actually cleaning an m AP sensor itself, everything's plastic,
(14:45):
and you want to a plastic safe cleaner that's going
to flush out those contaminants and it's going to dry
really quick and most importantly not leave a residue behind
any type of oially residue or anything else. They're going
to skew those sensor readings.
Speaker 2 (14:59):
Now, now suffice it to say that mass airflow sensors,
you've got a mass airflow sensor cleaner too. You've got
a mass airflow sensor cleaner. You've got a uh, you know,
you've got contact cleaner, electrical board cleaner. So if you
guys are making a cleaner for a specific application, it's
not just because you want to print out a bunch
of different cans. There's a specific reason for each and
(15:22):
every product, and we're better off using it than trying
to be adventurous on our own, right.
Speaker 3 (15:27):
Exactly, mass airflow sensors are so sensitive that the QD
contact cleaner could actually damage an MAF sensor, right, So
it's actually a very specific, unique formulation for cleaning maf sensors.
Speaker 2 (15:42):
Cool means Scott. It's been a pleasure, sir. Where can
the listeners get more information?
Speaker 3 (15:46):
They can go right to our website at seriously industries
dot com.
Speaker 2 (15:49):
All right, hey, listen, you'd be well. You have a
great rest of the weekend and we'll talk to you
against soon. Thanks for taking the time. I'm Ronning any
and the car Doctor. I'm back right after this. Get
you kid on the road.
Speaker 1 (16:00):
