Squealing

[Mick]

Hey my car has just started getting a squeal from the rear brakes, the pads have been on there for years but i dont drive it much so when i looked there is lots of meat left on the pads, like alot and the rears dont have wear indicators on them like the front pads do so couldnt be wear indicator noise anyways, now im thinking it might be from the handbrake shoes on the inside of the disc, so my question is this common or even possible? i had a read up and i read that some people were getting squealing from there rear pads and they had to file the edges of the pads but its weird cos they have been good for years and have obviously bedded in so what are your thoughts on this?

The front brakes on my Pulsar were making grinding noises and had a wobble. Lots of meat still left on the old pads.

I replaced the rotors and pads with new cheapie stuff, silent and smooth (brakes better as well, pedal came up too). Food for thought.

When does the squeeling occur?

[GTRPSI]

If it only squeals on braking, take the pads out, check if they have a 45 degree chamfer on the leading and trailing edges of the friction material, if not make them with a grinder, and thow a little copper grease on the back of the pads where they contact the piston and caliper.

Use it sparingly and dont get any between the pad and rotor contact face, or in other words the friction points.

Most noise is usually the pads backing rubbing against the caliper and piston contact points.

Glazed rotors will also produce noise, a light skim should bring them back to life if they are thick enough.

I have similar on the pathfinder, though only in reverse at low speed (it's a bitch when I'm trying to quietly reverse out of the garage at 4am).

Did all of the above and nothing helped. Meh I just keep the windows up and crank the tunes a bit louder - that seemed to make the problem go away.

deglaze them, drive up to 80-100 and brake hard on a quiet rd all the way to a stop. Do it 4-5 times in a row

If that doesn't stop it, pull the pads and do what gtrpsi said, while out also use pads on some emry paper and take off a layer (sand for about 30-60 seconds each). Gife the rotors a quick scuff.

Not suppose to come to a complete stop. Meant to come close to stopping

There's been multiple thread on this in the past. Searchy time.

Do you have the factory anti-squeal hardware? If not, get it.

thanks everyone for your info, yeah when i put the pads in years ago i cleaned the shims and coated them with the proper stuff exactly like im supposed to, as i said its been perfect for years and it just started happening and im still not sure if its coming from the pads or the handbrake shoes or even the bearings, i know i need to jack the rear up and give the wheels a turn to find out where its coming from exactly, but now that i have some hints from you guys it will make it much easier when i work oht whats making it squeal, oh and it starts for a second or two at highway speeds and almost constantly at low speeds

Sounds like a rock

I basically come to a stop, gtr wont engage 1st otherwise, then you can run it through a few gears

[Hadouken]

If you stop then you are doing it incorrectly, and you dont have to engage first lol, thats probably just you burning up the road.

You are meant to get on the brakes from >80 down to say 10km/h, repeat a few times then let the brakes cool for a few minutes ,note you are still driving around, then repeat the whole process,
