About 30 each for rotors and 2 hours (or less) in labour.
Possible wrong rotors???
remove tire calipers brake assembly then pull your rotors off i would recomend putting new brake pads if your putting new rotors you will need a special puller for the rotors cause they are pressed on
The traction control shouldn't affect the break system. The operation would only be affected by warmed rotors or bad calibers.
Something to check would be your brake shoes and rotors to see if they are worn, another thing to look at is the brake fluid reservoir full? Have the brakes been bled? Then the only possible answer left would be brake booster failure
your brake rotors are warped. You should repalce you brake pads and have the rotors resurfaced if possible, or replaced.
Possible that the rear sensors are broken.
Break rotors heat up very fast while drive and stopping, todays technology in my sense isn't the best on rotors. If you have a heavy foot and brake hard, that will contribute to warped rotors. Sudden stops will also case warping. Most brake Specialist (Les Shwab) recommend on new cars, and new rotors to brake easy, (light foot) on your new rotors for the first 1,000 miles of the rotors life. That way they have time to brake in.
Yes. Although it confuses me as to why you would want to use old rotors for a brake job. New ones are cheap.
Rear Calipers sticking. Replace the calipers and drain and flush the entire brake system. In addition, replacing the rotors when you install new pads will make them last longer. Worn rotors will not mate properly to the new pads, causing uneven wear.
Warped brake rotors.
Braking would deteriorate and you could damage the rotors.
i would suggest getting an m.o.t I suspect the brake rotors are warped. Machining or replacement of rotors is necessary to correct that problem.
