Just got done with my rear brake job and tune up. Rear brake pads, rotors, calipers, and 8 Denso spark plugs. My Hundy has 130k mi, and it appears the rear brakes were NEVER replaced!! Parking brake system was rusted shut, making all kind of noise, so for now, ripped it all out. Caliper was seized up and needed new. Spark plug seems replaced once and not in too of a bad shape, but piece of mind, I replaced all. My Mobile Mech done it all for $110.00 I think it is a good price.
