What is a Combination Parking Brake (CPB) caliper?

A Combination Parking Brake caliper, like this Wilwood unit, integrates two braking functions into one component. It uses hydraulic pressure for your regular stopping power and a mechanical locking mechanism to act as a parking brake.

What kind of brake setup is this caliper best suited for?

This caliper is a good option for rear axle disc brake conversions or upgrades, especially on vehicles where traditional drum brake parking mechanisms aren't easily adaptable. It helps provide balanced brake bias when paired with the right rotor.

Does this caliper come with rotors or mounting hardware?

This product listing is for the Wilwood caliper only. Rotors, mounting brackets, and any necessary hardware are typically sold separately and should be confirmed before purchase.

Product Details

What you get here is a Wilwood Combination Parking Brake (CPB) caliper, specifically the left-hand (L/H) unit in a striking red finish. This caliper is designed to handle both your primary hydraulic braking needs and act as a mechanical parking brake, making it a smart choice for rear axle disc brake conversions or upgrades where traditional drum parking brake systems aren't suitable. It features a 41mm (0.81 inch) piston and is intended to work with appropriately sized rotors to achieve balanced brake bias, complementing front brake upgrades.

This caliper uses a clever hydra-mechanical system. Hydraulic pressure engages the brakes for stopping power, while a separate mechanical locking mechanism engages when you need to set the parking brake. This dual function simplifies your brake setup, especially when converting from drum brakes or when your rear axle configuration doesn't easily accommodate internal shoe-style parking brakes. Wilwood has redesigned this unit to offer more flexibility for custom builds and rear disc upgrades.

When you're matching this caliper to a rotor, aim for a diameter that helps create balanced brake bias. This ensures your front and rear brakes work together effectively, providing consistent and reliable stopping performance. It's a well-built component that offers a practical solution for many custom brake applications.
