This brass guide bushing + steel slider pin kit is built to tighten up caliper movement, reduce deflection, and help your brake system apply pressure more evenly—especially on spirited street driving and higher-heat setups.\u003c\/p\u003e\n\u003cp\u003eBrass bushings offer a firmer, more stable guide surface than soft rubber-style designs, while the upgraded steel slider pins restore smooth, controlled caliper travel.
