Every car Ive ever seen, the front rims always are dirtier due to more brake dust because the majority of the brake force is applied to the front.. Not my car.. My rear get way dirtier.. Using the same pads.. Is there some sort of problem with my front brakes .. Could my ABS be going?

 

are you sure the rear caliper isnt stuck in a position where the pad is constatnly making contact with the rotor. the only itme ive seen a car with brake dust to a heavy extent is a car that isnt washed often or theres a problem with the caliper.

 

Check to make sure the e break is fully released at the caliper.

Also is it both wheels or only one side.
