Help please,
I had new brake pads fitted to my cerbie at the last service 3 months ago. Brakes were a little noisy at first but as time has gone on they have just got worse. Its not even funny, they are SO loud that i dont even want to brake.......bad idea.
Does any one else have really noisy brakes or is it just me?????????????????

I think they are called green stuff?
Any help would be greatly appreciated.

Thanks
Scott

You dont say what model but as yours is a 97 I imagine it's a 4.2. My 4.2 did squeak to some degree bu not very badly. My 4.5, in common with most other 4.5's can squeak very loudly, especially when the brakes are hot but I have managed to reduce it quite a lot by doing the following.
1) whip out the pads and make sure there are anti-squeal backing shims fitted. If not, get hold of some because some klutz forgot to put them in at a pad change.
2) Get a tin of high temperature Copaslip (copper based grease) and very carefully coat both sides of the shim with a thin film of this before reassembly. Be sure not to get any on the friction material of the pads otherwise no brakes and a hairy moment!
3) Make sure that the registers cast into the calipers on which the pads sit are clean, smooth and burr free and that the pads slide in easily. Binding here can cause squeal
4) If after the above you still have unaccepable noise there are other more radical solutions. I can't remember if 97 4.2's had slotted pads. The idea of vertical slots in the pads is supposed to be to prevent a build-up of fine brake dust on the pad surface which can cause squealing problems. If your pads aren't slotted you can get them cut. The slot needs to be vertical, dead centre, 1/16" wide and extending to within 1/16" of the steel backing. An engineering shop can do that with ease.
Alternatively, go for a pad change to a different material from original fit. AP Racing at Coventry are a really helpful bunch of guys and can rattle off pad alternatives for you including low noise materials.

Good Luck

Also, try removing the leading edge of the brake pad with a file. Worked for me.
