Fitment & Compatibility
The bracket must center the caliper over the rotor and locate the friction material at the correct radius. Check hose routing and bleed orientation through the full suspension and steering movement.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
The narrow Superlite 4R has four pistons, radial attachment and removable center bridge access to type 7416 pads. Check the specific rotor-width version before ordering another caliper from the same family.
With over 20 years of experience, PMB Performance can help compare piston configuration and mounting geometry. Share the existing brake package and measured rotor dimensions before ordering.
