Product Description
Replacement seal kits for 'seal in bore' type racing caliper applications which have no dirt seals.Brake calipers are a safety critical item and AP Racing recommend that calipers are reconditioned and piston seals inspected regularly to maintain optimum performance. Where calipers have been subjected to high temperatures or have been used in adverse conditions such as rallying or off-road, the calipers should be reconditioned and seals replaced more frequently to ensure safety and performance levels are maintained.We offer a full range of replacement seals, pistons and other spares required to maintain your calipers in optimum working condition.Please note - Where multiple dimensions are shown in the 'Caliper Bore' drop down menu, this is for differential bore calipers which have 2 or 3 different piston sizes in the same caliper.Each kit contains seals for one caliper.
