I have a lot of brake dust on rims, we have replaced calipers, brake pads, rotors, every 3 to 4 months. just wandering if there’s something else were missing
Sounds like you are driving with two feet or are using the cheapest brake pads available. Brake pads should not be worn out inside of 3 months. If you have found the brake calipers sticking, the caliper hoses may be the cause.
Brake Dust on Rims
To help reduce the amount of brake dust you will want to use a quality ceramic brake pad. This should cut down on the amount of dust you are seeing.
