RE: New brake pads – rumble & vibration

[Andy Campbell]

Greetings

Recently had new brake pads fitted to the rear brakes and there is a concerning rumble and some vibration.

The brakes (new pads) are fairly recent and have done about 200 miles since

The noise / vibration did go away on a 60 mile drive but has come back

Any input ?

Possibly the wrong pads fitted? There were many versions of the rear callipers fitted to these cars over the years and its important to fit the correct ones for the chassis. May not be the brakes "per se " but something was damaged when the pads were changed or something that just happened by chance around the same time. IF ITS BRAKE RELATED you should experience a notable change in symptoms when applying the brakes gently while driving as any excess slack or movement may be taken up.

RE: Brakes - noise

Hi grober,

Thanks for your response.

Just to clarify (sorry) - there is no vibration / noise whilst driving – this only happens (noise / vibration) when I apply the brakes.

Cheers mate

May be a reflection of the state of the rotors then-- the previous pads will have " worn in" to match any surface imperfections/scoring/rust on the disc. The new ones won't--- they will eventually "wear to shape" and become quieter but possible indication the rear discs are warped or heavily scored?? If the discs are OK then its possibly some sort of problem with the new pads?
