i had brake squeal recently so i stripped, copper eased and rebuilt my front brakes,. stripped cleaned and reassembled my rear brakes. the bloody squeal is still there! its only when the brakes have warmed up a little. any ideas?

Pads.

It could be the make/material of the brake pad.

I've got the same problem (drivers side) and im using green stuff brake pads, are you by any chance using the same fifi the shiney? because then it could just be them pads are a bit squeaky

"Fast Road" Pads can cause Squeeks.

Its why i was asking what make/grade pads he has.

i am using stock ferodo pads. the discs are stock too.

Put copper grease on the back of the pads, the surface that is pushed by the piston. Don't put so much grease that it falls/squidges out onto the brake disk! just get a brush and apply it liberally. Always works. Don't ask me how!

i was told to chamfer the pads with a file to take the edge off of them. i dont normally have this problem tho. i always liberally apply copper ease to the pads anyway. i may try a different pads when money allows. its not a big issue tho as they stop on a dime still.

Due to the material used to make brake pads, they tend to be alot harder than when they used abestos. This tends to cause groves in the discs surface which brake dust gets trapped in. Have you checked the surface of the discs ?????

Also might be worth getting the discs groved to help with venting. Pad material gives off gas when they get hot. This is what causes brake fade. Cyclone solutions in Wickford can grove discs at a cost of £15 per discs. Get yourself a cheap set of discs and have them groved, cheaper than buying them from the shops at a cost of approx £90.

Or simply turn the radio up louder thats what I do.

i see where your going but thats not the best advice, imho

the whole point of grooved discs is that it gives the brake dust and gases somewhere to go, thus improving braking performance.

i wouldnt recommend getting your discs machined, especially when there not intended to be grooved. i would hazard a guess and say they would be highly prone to warping and cracking
just spend the extra dosh if you want grooved, then you got a guarantee.

SHIMS - WHEN DO I NEED THEM?
Many semi metallic pads (those containing steel fibre) come fitted from the factory or aftermarket suppliers with rubberised metal shims on the back to prevent rattling and squealing. This is because of the type of material they use. At EBC we very rarely use shims because in 99 cases out of 100 we do not get noise, due to the non metallic nature of our pads. In certain cases however and in certain types of use, especially “under-use” shims may be necessary to quieten a pad. These can be obtained from EBC free of charge by simply calling 818 362 5467 and stating the type of vehicle. These will be sent out to you and again reminding you that the installation costs are for the customers account, we do not warranty this fitment charge or consider it part of our guarantee.

might help if you've tried everything else...

Ferodo pads always squeal for some reason. Ive been through 3 sets of Ferodo pads, always copper greased the backs and all 3 sets have squealed!! Funnily enough only in damp conditions! I no longer use Ferodo pads because they always squealed and they make massive amounts of brake dust, and i dont think they are particularly good. Go with some EBC pads, had no problems since.

My understanding of why brakes squeel is that its the pad vibrating against the caliper/carrier at a certain frequency causing the noise. That is why the copper grease can help as it "dampens" the tiny vibrations, and it's the same principle for the shims. Alot of cars come with a shim of some kind from new to prevent squeel (Nissan Primera P12 rears for example!)

i want to ask something about the brake...i have taken out the wheel and i spin the disc myself but i can still hear squeal sound.y is that?

[timbo]

Might be nothing to do with you brakes and be your wheel bearings.

[sidq]

i just changed the wheel bearing and im pretty sure its bcuz of the disc or pads but im not really sure where to look at.

[sazal]

Mine squeak too its so embarrassing I changed my discs and pads for the bog standard minisport ones. Ive tried putting copper grease on, but it didnt do anything
