Squeaky brakes

[Virtual_Unknown]

[Virtual_Unknown]

anyone?

 

[ViolentJ]

thought it was brake dust?

mine tend to start squealing when the pads need replacing

 

[RobFenn]

In what conditions/circumstances?

 

[Virtual_Unknown]

normal conditions, any time i press the break pedal theres a high pitched squeal

[JAY172]

brake dust,uneven wear on the pad/disc surface,corrosion on the discs and some cheaper brand pads can cause it.

 

[Chris1.4RT]

copper grease on the backs of the pads helps reduce it.

 

[JAY172]

squeaks can also be caused by the pads vibrating thats why car makers fit shims on some models.

 

[Virtual_Unknown]

so the easiest way to get it to stop is to change my pads?

 

[Chris1.4RT]

id take them out and try copper grease on the back, sounds daft but often helps. costs about £4 a tube

 

[JAY172]

remove the pads,clean up the pad material surface,copper grease the back of the pads and grease all caliper slides etc.rebuild and try it.there is also a paste that you can paint on the pad surface to help prevent squeal.not excellant but has been known to work,having said that though some new pads might only cost a little more than the paste so new pads would be more economical.

 

[Chris1.4RT]

do as Jay says, with the calipers too, put grease on the bits of the calipers that the edge of the pads touch, stopped my squeaky brakes. Dont go overboard with it though, you dont want it getting on the pads or discs.

In most cases incorrect pad placement on teh disc, typically from the leading edge touching first and vibrating the pad.

Just do what Jay said, as the slides tend to stick on the front slide, it corrodes easier than the rears for some reasons, probably exposure.
