what causes brakes to squeak/squeal?

put new pads (just cheapy motoquip) in me RS2k, then they started squeaking really bad whenever you brake,

i've got a 20mile drive to work in stop/start traffic its slowly driving me insane!!

been out and bought another set of pads, thought i'd replace discs as well this time to see if that sorts it, (motoquip discs and ferrodo pads)

guess what its still doing it!!!!!

at first it would start after about 5min of driving or as soon as you stamp on the peddle hard,

with these new brakes you mite make it 10min without it happening now

could it be the calipers causing it?

please help?

 

did you put copper grease on the back of the pads?

 

As above

Changed mine and done the same, i did use copper grease but not enough!!!!

 

anti rattle things catching on disc ?

 

ah, how much copper grease is needed?

i did use copper grease, but i may not have put enough on too!

what are these anti rattle things mate?

 

the squeak is from the pads rubbing in the carriers
clean them up and refit with a little smidgen of grease on them and it should solve the problem

 

try braking very hard a few times (give them a good run) and see if they still do it.

mine squeak when the car gets driven like miss daisy, but then they are track spec jobbies.

 

If more copper slip / GRease doenst solve it. Try sanding the edge of the pads to a 45 degree angle rather than the 90 they are from new.

Only do a few mms though!

 

Just put some WD40 on it

Dave take this mans advice, plenty of WD40 and the noise will go away

 

*ucking ignore that advice mate thats just bloody dangerous!!!!

Grease the contact face of the disk liberally with goose fat and the pad face with GT85, it has teflon in and far better than WD40 IMHO

 

Oh yeah:

sorry just had to do that.

Since the switch from Aspesdos brake pads they all do it now

 

Cawoods that dumb he will probably try it

 

Turn the radio up

 

Dont do this you need to bed the brakes in.

Chances are it's your rear brakes are the standard drums?

 

Dont brake... simple really
