[QUOTE="oscar, post: 166777, member: 2757"] you are correct man. the brake discs could be warped, although this isn't very common but you any garage can check this for you by using a Dial Test Indicator (you could do a DIY version by using a straight edge and feeler blades but this won't be so accurate...just place the straight edge over the face of the discs and if you get anything more than 0.04 then you're discs need to be binned) other problems could be worn brake discs - down to the metal, or to the wear indicatior. this would feel like a metalic scraping noise with vibrations felt through the steering wheel. my suspicions would point to the brake discs though, check their thickness and compare them to the minimum disc thickness which i'm sure you could find somewhere online. when discs reach their minimum thickness, they have lost so much mass that their capability to dissipate the frictional heat created through braking that they can deform and loose their shape. an outside cause could be a problem with your ABS system, but you'd have a fault code for that so i wouldn't worry about this whatsoever. .... on the AC note, it sounds like you've got an AC clutch on it's way out buddy. easy enough job to change, i'm sure you could do it!
