Horrendous Brake Squeal!

Post by kis » Sun Jun 09, 2019 3:55 pm

Must be the piston in the calliper, not retracting properly. Someone on the forum is selling a complete set. Might be worth getting just for the rears? Even though you’ve had (screeching) a while you’ve done all the hard work changing and testing all associated components.

Ok so today I did the following

- Stripped both rear sides down, discs off etc.
- Cleaned both sides, all components using a wire brush and sandpaper.
- Greased slider pins
- Adjusted hand brake so it’s not fully up, basically adjusted it off a bit
- Copper greased back of pads again
- Ran some sand paper over the face of the pads

Took it out, still squealing!!! Made no difference at all.
And the anti-rattle clips?

Both fine, removed them both and cleaned them up etc.

The ones in the for sale section will not fit mine which sucks.

Does anybody know if the E46 calipers are the same? Assuming they came off a 316/318 car and mine is the 2.0l.

Cheers

Have you checked those two being broken (on here)? I'm sure one of them is a 2.0?

Bought two replacements from a car being broken on here, hopefully they fix the issue!

Thanks all
