Passat B6 Rear Brake Caliper - 2005-07 (282mm Brake Discs) - Right (TRW)

This rear right brake caliper is a direct replacement for Volkswagen Passat models equipped with electric parking brake (EPB) and PR code 1KU. Designed for use with 282mm solid rear brake discs, this TRW-manufactured floating caliper restores correct braking performance, handbrake function, and electronic integration on the rear axle.

RHD note: On right-hand-drive vehicles, Right = Drivers Side.

What this brake caliper does

The rear brake caliper houses a 38mm piston that applies hydraulic pressure to the brake pads when the brake pedal is pressed. Friction between the pads and disc slows the rear wheels, contributing to vehicle stability and balanced braking.

On EPB-equipped Passat B6 models, the caliper also integrates with the electric parking brake motor, allowing the system to automatically apply and release the handbrake. A correctly functioning caliper is essential for safe braking, reliable EPB operation, and preventing uneven pad wear or warning lights.
