Can anyone tell me what reasons would make a set of brake pads wear differently from left to right?

I'm talking 4mm wear on one side and 10mm on the other, new calipers, car doesn't pull to one side, can't feel drag, calipers bleed ok meaning lines are clear..

I'm talking drivers side set vs passenger side set, pads are worn the same in each caliper.

Maybe you have two different brand Rotors ! Are you running shields on both sides ? Which side wears most left? Dust and grit from road side on country roads ? Or maybe the side that wears most has a slower releasing Caliper.

Hi your slack to me mad mini.
May be the right hand side was scared of the high speed at wakefield and was braking earlier than left side at the end of the straight, thats why you spun or may be you push the brake pedal to the right more than the left or may be the right disc was more abrasive than the left with all them slots and holes you have in them, just let them bed in and see what happens,swap your pads over and see what happens.

I'd suspect the front brake hoses, fit new if you've not done already. I had the same prob on Paul's Clubby when I fitted Brad's Honda discs. One was swelling closed....

Loose wheel bearings? Hard spots on one rotor?
