OTK Tony Kart Rear Brake Caliper Piston Seal – Part #0082.D5

OTK Tony Kart Rear Brake Caliper Piston Seal – Part #0082.D5

This is the genuine OTK replacement piston seal for the rear brake caliper. The piston seal is a critical part of your braking system — it keeps hydraulic fluid contained within the caliper and ensures proper piston movement. A worn, cracked, or leaking seal will result in a spongy brake pedal, fluid loss, and ultimately brake failure on track.

Whether you're doing a routine caliper rebuild or chasing down a brake issue, this is one of the first components to inspect and replace.
