Does your car pull to one side when you hit the brakes or let go of the wheel? Do you notice one wheel seems to “get hot”? Are your calipers leaking or stuck even though you have cracked the bleeder nipples? You may need to rebuild your calipers. These kits include seals, piston clips, and boots; and with a little labor and paint, will look new as well. Reasonably priced, they sure beat the price of a new caliper!
