Brake Calipers
Find replacement and performance brake calipers for classic cars, muscle cars, hot rods, and trucks. Explore GM D52 and D154 calipers, Wilwood performance options, and vehicle-specific replacements for front and rear disc brake systems.
Brake Caliper Options for Classic and Performance Builds
Brake calipers in this collection cover both replacement and upgraded disc brake applications for GM, Ford Mustang, Mopar, classic trucks, muscle cars, and hot rods.
POL carries popular GM D52 and D154-style calipers along with vehicle-specific replacements designed around different rotor thicknesses, mounting positions, and front or rear brake configurations.
Performance options include Wilwood dual-piston billet aluminum calipers and other upgraded designs with different piston sizes, bore dimensions, and finishes, including black, red, polished, and platinum.
Because caliper compatibility depends on rotor thickness, mounting style, brake hose connection, wheel clearance, brackets, and the rest of the braking system, the collection includes several configurations built for very different disc brake setups.
FAQ
How do I choose the right brake caliper for my vehicle?
Start with your vehicle year, make, and model, then identify the brake system currently installed. Check the caliper type, mounting configuration, rotor thickness, front or rear position, and brake hose connection. Some products in this collection are direct replacement-style calipers, while others are performance upgrades. If your vehicle has an aftermarket disc brake conversion, choose the caliper based on the brake system components rather than the vehicle application alone.
What is the difference between D52 and D154 brake calipers?
D52 and D154 refer to different GM-style caliper configurations, and they are not automatically interchangeable. They can differ in mounting dimensions, piston size, brake pad shape, and the rotor sizes they are designed to work with. This collection includes both D52 and D154 options, so identify which configuration your existing brake system uses before selecting a replacement or performance caliper.
How do I know what rotor thickness my brake caliper needs?
Check the specifications of your existing brake system or measure the rotor and compare it with the requirements listed for the caliper. Calipers are designed to operate within specific rotor-width ranges. For example, products in this collection include D52 calipers designed around different rotor thicknesses, while the Wilwood D154 dual-piston caliper shown in the collection is designed for a 0.81-inch-wide rotor. Matching the caliper to the correct rotor thickness is essential for proper fitment.
Should I choose replacement or performance brake calipers?
Replacement calipers are a practical choice when rebuilding or maintaining an existing brake system and you want to retain its current configuration. Performance calipers may be better suited to modified vehicles or drivers looking to upgrade from traditional cast-iron designs. The collection includes Wilwood billet aluminum dual-piston calipers as alternatives to several common GM configurations, giving builders performance-oriented options without necessarily changing the entire brake system.
Can I replace a factory GM D52 caliper with a Wilwood D52 caliper?
Certain Wilwood D52 calipers are designed as direct bolt-on alternatives for compatible GM D52 applications. However, you still need to confirm rotor width, mounting configuration, brake hose connection, wheel clearance, and the requirements of your specific brake system. For example, POL's Wilwood D52 dual-piston caliper for 1969-91 GM applications uses the OE-style mount and is designed for a 1.25-inch-wide rotor.
Are brake calipers sold individually or as a pair?
It depends on the product. Some calipers in this collection are sold individually and require two for an axle. For example, POL's Wilwood D52 and D154 dual-piston calipers are sold individually and can fit either the right- or left-hand side in their specified applications. Always check the individual product details to confirm quantity, side, and whether brake pads or other hardware are included before ordering.
What should I check before installing new brake calipers?
Confirm the caliper mounting points, rotor diameter and thickness, brake pad compatibility, hose or fitting connection, wheel clearance, and whether the caliper is intended for the front or rear brake system. You should also check what is included with the product, since pads, hoses, fittings, brackets, and other components may be sold separately. Looking at the complete brake setup before ordering helps prevent compatibility problems and ensures the new calipers match the components already on the vehicle.
