Re: [MBZ] Ceramic ATE brake pads

2012-02-07 Thread Dieselhead

Every time I've developed brake pulse problems it came back to a warped
rotor.  Why would it not be the case on MB car?

Thanks in advance. I await your learned advice.

Grant...



That is probably true in a 0 humidity environment like AZ, but in the 
north, if the car sits a long time, particularly in the 
winter/spring, the rotors rust, and they rust differently under the 
caliper.  This causes a pulsing the same as a warped rotor.  Unless 
there is really severe pitting under the caliper, this will often go 
away with hard braking.


I recently had pulsing on a non-MB veeehicle, and in that case, some 
genius decided to use ball bearings for the front wheel bearings to 
save a nickle.  When one bearing wears out or disintegrates, you get 
pulsing in the brake.  I would guess on an MB that extremely loose 
wheel bearing could cause the same situation.

Basically you're trying to get the brakes real hot in a controlled 
manner as opposed to getting them hot the first time you have to slam 
the brakes on hard.
However this is sometimes hard to, as you need a place where you can 
speed up and slow down, without other traffic around, spose a big 
shopping centre car park on a Sunday morning?

cheap pads were) but great.
A couple weeks ago I was in a shop and chatting with the guy that runs the 
place. I'd mentioned the Akebonos and he said those were top of the line pads 
but that any ceramic pads were good pads, even the Raybestos brand. He says 
they push all customers to ceramics now as they have fewer complaints.I asked 
if that was a good idea since they last longer and he said that fewer 
complaints brought in more business than doing more work on each car. I can't

after 20,000 miles I can't detect any significant wear of the pads  
or rotors.
I used the PBR pads (and rotors maybe? I forget) on my '83 240D  
when I was trying to keep costs as low as possible. Somebody on  
here (Jabba maybe?) derided them but they went 25,000 miles with  
no issues at all.
My '84 needs new brakes in the spring and I intend to do Akebonos  
all the way around and never do brakes on that car again.

That's promising--my '87 has 230K mi on it, the last 25K or so on its third
head.  No measurable timing chain stretch, and it doesn't use a drop of oil
between changes.

I think the manner in which you utilize the brake pedal has something to do 
with brake life too. The brakes in my car last a looong time. I never did 
brakes on my '85 190D and I drove that car 90,000 miles, who knows when the PO 
had last done brakes. But I drive mostly on the highway and I use the brakes 
and get my foot off them.
My wife is hard on brakes, her vehicles need brakes every 2 or 3 years but she 
drives mostly in town and occasionally when she's driving I'll say Why is your 
foot on the brake? And she'll reply I dunno I think sometimes she uses the 
brakes just for something to do.

It is highly recommended that new rotors are fitted with new ceramic 
pads, the bloke was a bit vague but he said something about the pads 
transferring some sort of material onto the rotors as they seat themselves.
Perhaps the problem is people stick ceramics onto old rotors and then 
find that the rotors are eaten up but there is still plenty of meat on 
the pads.
I think if you put on new pads and rotors and pads and get 100k kmhs out 
of them, then you are doing pretty well, however this is variable 
depending on driving situation, around here life is pretty hard for 
brakes, lots of short runs in a hilly environment. Whereas lots of 
highway miles will not eat up brakes.
Generally speaking MB rotors will last for about two set of pads but if 
ceramics work on a 1:1 ration but get a lot more miles and less dust, 
noise, etc then it is worth it.

[MBZ] Ceramic ATE brake pads

2012-01-31 Thread Hendrik Fay
Just to throw in a bit of MB related stuff, one of my front wheel 
bearings is on the way out and whilst I was waiting for the old fella in 
the parts place to shuffle out the back to find some, I happened to spy 
a trade mag ad advertising ATE ceramic pads with the usual promise of no 
dust and longer life.
So I asked the fella behind the computer if they make em for my old 124, 
sure enough front and back, unfortunatley I just replaced mine not long 
ago so will put up with the black wheels a bit longer.
