Rotors, pads and calipers replaced on both front tires in dec. 09, brakes sometimes had to be pumped to get them to catch and brake properly. Then, last month, they just stopped working-pedal goes all the way to the floor. Brake fluid is completely full and the passenger side tire gets covered in brake dust while the driver side tire stays clean.

the proportioning valve is probably faulty. they need to be bleed too, somehow air entered the system, maybe because the fluid was low months back and was topped off. but air had already entered the system.. may have a small hole in one of the brake lines, wont know until it is inspected.
