If your brakes are spongy, or your caliper is leaking, you may be able to service the caliper, rather than replace. We always recommend work on critical components, like brakes, be done by a certified professional, however, even with shop time, this may be a more cost effective solution than replacement. This caliper rebuild kit will service one caliper. Fits FJ40/45, FJ55, FJ60/62 – 9/1975-1/1990
