Restore consistent braking performance and eliminate uneven pad wear with this solid brass front brake caliper guide bushing kit. Designed to replace the factory rubber guide bushings, this upgrade significantly reduces caliper flex and twisting under hard braking, resulting in a firmer pedal feel and more predictable brake response.

Factory rubber bushings are prone to deflection—especially when worn—allowing the caliper to shift during braking. This can lead to uneven pad wear, rotor deposits, and inconsistent braking performance. Solid brass guide bushings provide a tighter, more controlled caliper movement, making them an ideal upgrade for spirited street driving and track use.
