Description
Brake caliper performance depends on seal integrity—worn or degraded O-rings compromise piston travel and invite fluid leakage that degrades braking response. The Wilwood 2.38″ Round O-Ring Kit supplies the elastomer seals you need to restore your calipers to factory specifications and maintain consistent pressure during hard braking. This 4-pack gives you the redundancy serious racers and dedicated mechanics expect.
