Product Description:

The RCW12103 ball bearing set is the main carrier part in dual-piston brake caliper systems, transmitting the mechanical power from the lever mechanism to the pistons. The assembly acts as the central component that withstands the highest load within the brake caliper and ensures the synchronized operation of the pistons.

The condition of the RCW12103 is critical in caliper repair, caliper overhaul, and brake caliper repair kit applications. Wear in the caliper body or failures in the ball bearings disrupt the brake pad pressure balance. This leads to serious problems such as uneven brake pad wear, vibrating braking, and loss of brake performance.
