Brake pad question

Brake pad question

Postby Solorange » Sun Jun 05, 2005 6:37 pm

I changed my rear brake pads this weekend and i hear the new pads rubbing against the rotor. Its a soft quiet noise. I pushed back the cylinder with a c clamp. There is no squeaking. It used to squeak with the worn down pads. But I was wondering if this is a problem or if i just have to drive the car a bit to wear in the new pads and if they will wear to the point that they dont consistantly rub. Thanks in advance for your input.

So the brake pads dont rub anymore. They just had to wear in. But now they squeak. They work fine. Anybody have any idea why brand new factory brake pads squeak?

This squeaking problem of new brake pads is apparently a common one for Toyota's and Honda's, for some reason. My new brake pads do the same thing. The noise is worse when the car is cold and when there is moisture in the air. The dealer assured me that it was not causing any harm to the rotors or other brake mechanisms. I am quite annoyed by it though!

Someone I work with told me i have to put on this special brake grease that goes on that plate that goes over the brake pad. I think he said it was blue. He said that is why they squeak. I followed the haynes manual and it never mentioned that, and how could that stop the squeaking. Wouldnt the squeak come from the pad rubing against the rotor?

Yes you need brake pad grease. Put it on the backplate of the pad, the side where they touch the caliper. I It can be any color i guess, ive seen it in blue and grey.

Without this grease, it will squeak like mad. I think its from friction between the backplate and the caliper when stopping the rotor. Some pads some with the grease. If yours didnt come with it, you can pick it up at any automotive store.

Revival.

Is this blue stuff (disc brake quiet) safe on the piston? I applied it liberally to the pad and to both inner and outer shims, but where the shims meet the caliper, I didn't put any. I still have horrible squeaking. Should I apply this stuff between the pad (technically outer shims) and caliper (inner piston side and out)?

did you turn the rotors when you changed the pads. you always want to
put a new suface to a new surface. the rear rotors could be galzed from heat. this is most likley where your noise is coming frmo. the brake grease is always a good idea to put on but the greese is more for stoping the brake pads from getting cocked and causing a chatering noise. hope this helps.

Not that hard man.
All you need is a 12mm or 14mm socket to get the caliper off the rotor and then take the old pads off and use some light sand paper on the new ones and put them in the reverse order you took the olds ones off.
And don't forget to tighten the bolts for the caliper to the bracket as hard as you can.
Also use a 6 point socket and not a 12 point, cause you will risk strippin' the bolt if you can't get on all the way and your elbow grease could loosein' how it sits on the bolt, and you could hurt yourself.

My rotors are new Brembo blanks.

Again, is disc brake quiet safe to directly touch the caliper and especially the piston? I think the fact that these mating surfaces are dry is causing my squeal.

Yeah do what he said but he forgot to mention that once you take the old pads off you need to compress the piston back in the caliper. I did this with a c clamp. Also you should get your rotors turned down to get rid of the squeal just like dgdtech said. I never did that cause I was planning on getting new rotors but I never got around to it yet so they still squeal.

The squeal comes from the high frequency vibration of the pad. This blue stuff (disc brake quiet) stops the vibration = stops the squeal.

As your colleague says, this goes between the new pad and backing plate (a.k.a. shims). I did exactly that and still have squeaking.

My question (third time is a charm)
Should this blue stuff also be used between the pad plate and the caliper? Is it safe or will it cause the caliper to sieze or rot away the piston rubber?

i put in new pads and new rotors and i didn't get any squeaking. i only had some squeaking when i did the initial braking and "burnishing" of the rotors, but after normal use i don't get it anymore.

check the pad support plates, maybe those are squeaking. the only thing i put grease on was the caliper pins. if you have aftermarket pads, you don't need the OEM shims; the aftermarket pads should already come equipped with 'em on.
