squeaking brakes

[dci120matt]

hi all again, i have noticed that when going at low speeds say up to 25mph i have a quiet squealing from the drivers side rear wheel, have people come across this before, i only notice if the drivers window is down and after i have applied the brakes, do you think it is the pad sticking? cheers

I had it ages ago and fixed DIY. The reason was rust forming under the stainless steel guides. As a result, the guides pressed against the pads thus preventing them from moving freely. I removed the rust, painted over the surfaces prone to rust and replaced the pads with GreenStuff from EBC. No problems since.

Please note: if your disks are damaged/worn/corroded, then replacing pads is useless.

Another reason for brake binding can be a stuck hydraulic cylinder. If brake fluid is not changed every 2 years, then the fluid gets saturated with water and causes internal corrosion. This is the characteristic of the fluid and not the car, so regardless of what is written in the service schedule, the fluid must be changed every 2 years!

In particularly bad cases the dealers first "clean" the pads, and then either replace them or replace the callipers. The main problem here is to convince the dealer that the fault is not caused by wear and tear...
