musical brakes

[Guest]

My brakes are driving me insane. They work fine, but when I brake at slow speeds (like in traffic) I get a musical concerto of squealing. I took it to a garage who said "Your back brakes are squealing". End of help.

I have checked the disks, pads, replaced the brake lines (when my husband hit one with a hammer [8|]) and even adjusted the hand brake (so it actually works now []).

The car stops beautifully. At higher speeds (like 70 to 50) there is no musical accompaniment, but slow down a bit and it's embarrassing.

What is wrong with them? Any ideas? What is there left to check? All ideas gratefully received!

You could try removing the pads & smearing some copper slip grease on the backs before replacing them. Be sure to put the pads back in the same place they came from i.e. don't take them all out at once & mix them up.

Are they standard pads? If somebody has fitted harder pads, they're likely to be a bit squealy.

It could also be that the pads and disks have become a bit glazed. Try taking them out, run them over with a bit of medium grade wet or dry paper and do the same to the disks. Then reassemble with a bit of copper slip on the backs of the pads. You'll need to do a little bit of bedding in (just a couple of heavy applications of the brake pedal should do the trick).

Helen -- are you using std Pagid pads, lots of 968 owners get problems of the type you describe with yours? if so this may well be the problem.

2 solutions, change to another make or do a series of really hard stops, this might scrub the discs and pads a bit and the noise might even go away.

I'm running Pagid's on my S2 and they play all sorts of tunes at lower speeds. The pads and discs have less than 500 miles on them, so I'm hoping they might bed in a bit and quieten down. It's bloody annoying when I return home in the early hours - must drive the neighbours mad!

Pagids are notoriously noisy. Better start practising your apologies to those neighbours! []

Hi all,

I'm also getting squeaky brakes after changing my discs and pads on my '87 S. I have used Porsche OEM Discs and Textar pads. I made sure I put plenty of copper grease on the backs of the pads and edges where they touch the caliper.

Is this just down to the fact that my calipers are almost 20 years old and so the rust and crud etc is just causing the squeaking ? I did tidy the pad carriers up as best I could with some wire wool but guess they are badly corroded...

Hmmmm another excuse to fit some nice shiny new calipers

Cheers
