Fitment & Compatibility
Compare the existing caliper’s piston area, rotor capacity and mounting pattern. Matching the body family alone does not guarantee that the replacement will clear the wheel or preserve pedal travel.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
This four-piston Dynalite uses internal fluid transfer in a spacerless body. Its 5.25-inch mounting pattern is only one compatibility dimension: rotor position, body clearance and hydraulic area also need to agree.
For a brake system assembled from individual components, PMB Performance brings over 20 years of experience. Contact us with the rotor, caliper and bracket information so we can help check the combination.
