Hi all , new to here as ive just gone and treated myself to a 300zx (jap import) after moving up in the world from my old beloved 200sx (s13) after it finally blew up :(.

 

When i bought it i found that the front brakes were really making a high pitch noise when braking normally to stop around town which was turning peoples heads for the wrong reason :(. I was told it had hardened pads on it by the bloke i bought it from, so a friend of mine advised me to go back to standard pads cos they are softer and will stop noise. I had the softer pads put on last monday and at first they were fine- no more squealing, but since then they have got progessively worse and are back to that bloody high pitch noise again :confused: There are drilled disks at front, and im now starting to wonder if this has anything to do with it. If any of you have any advice i would deeply appreciate it :))

I would do two things, firstly clean up the discs to ensure there is no glaze on them. I have a grit blaster, but if you're enthusiastic then then wire brush and glasspaper will achieve the same thing. Secondly, I would double check that you have the metal shims behind the pads and you have a smear of Copperslip in there.

As Andy said, make sure the shim kit has been fitted.

 

When i renewed my front discs the drivers side shim fell apart, anyway i thought nothing of it. But then the same side started squeeling really badly.

I put up with it for a couple of weeks. But yesturday we fitted the shim kit and took it for a spin around the block and its nice and silent again. No more embarassing noises! :nana2:

Ok great, ill check / do both. Thank for replies :) - hope it ends this noise as its driving me nuts
