Hello R33 Guys

[FalahR33]

Just wanna know why my brakes squeel all four of them loud when i apply brake. Even changed my brake pads to nismo s tune nothing changed.

Also a one way valve on the brake booster is missing. Does this normally happen in an r33? I got a gtst.

Do you have the shims installed behind the pads?

I think the one way valve is actually inside the vacuum line going to the booster.

Just changed pads. Didnt notice anything like missing shims. I checked the line, which by the way i changed it isnt there in it.

squealing brakes is caused by high frequency vibration, shims absorb the vibration, or you can use a brake rubber compound or a high temp grease, I used project mu backing plates, worked a treat

Yep no shims, get ready for squeal.

But actually my qfm pads are doing great with no shims haha

The shims are on the back of the pads.

Check if they even have shims. I had to swap the shims over from my previous pads.

Wouldn't hurt to machine your discs and try another set of shims too.

Never machine discs unless you have too, and it wont solve squeal
