skidder Posted July 18, 2011 Share Posted July 18, 2011 hi all, thanks for any advice in advance. Bought yellowstuff pads 600 miles ago.Running OEM brembo discs.All seemed well.Squeaky for a while but turned out ok.Now seem to have a grinding noise on slow or heavy breaking(very noticeable,seems like when pads are low, metal on metal). Also seems to be heavy wear on offside rotor, nearside is ok. Do I need to invest in new rotors? Phoned a mechanic I know and he says might be the new pads, give it a bit of time.. Its just bothering me now as I know my brakes are seriously important. Also only had the car 4 months. Don't mind spending a bit of dough but just want the best option.

Ekona Posted July 18, 2011 Share Posted July 18, 2011 Remove and refit, sounds like a stone or piece of road debris is caught between pad and disc. Depending on how bad the scoring is on the bad rotor, you may get away without replacement of them both. Quote Link to comment Share on other sites More sharing options...
andlid Posted July 18, 2011 Share Posted July 18, 2011 my yellowpads where REALLY aggressive on my rotors ((non-brembo setup)). Uneven wear of rotors make no sense unless you have different braking from different calipers. Did you measure the discs at all to see if they're shot?

ZMANALEX Posted July 18, 2011 Share Posted July 18, 2011 Also check that the back plate is not touching the disc. Best to get the wheels off and have a proper look Quote Link to comment Share on other sites More sharing options...
kano Posted July 28, 2011 Share Posted July 28, 2011 Check that the discs are not lipped, would explain initial squealing. Quote Link to comment Share on other sites More sharing options...
Wasso Posted July 28, 2011 Share Posted July 28, 2011 Check that the discs are not lipped, would explain initial squealing. +1 and potentially the grinding, it would also prove that your braking is not efficient either. I put Performance friction pads on my oem brembo disks and lets just say the wear was uneaven after 12 months. Changed rotars and pads, made a MASSIVE improvement!! Oh and no squeal either Another option would be to skim the disks, if there's life still in them. Quote Link to comment Share on other sites More sharing options...
Greekman Posted July 28, 2011 Share Posted July 28, 2011 It smells like a sticky caliper to me...easy to detect. Remove caliper, check movement of pistons with brake fluid lid off, remove dust seals and then recheck piston movement. Washing the pistons with brake fluid and a brush always helps Quote Link to comment Share on other sites More sharing options...
