Product Description These components are critical parts of a vehicle's disc brake system, specifically for "floating" calipers. They allow the caliper to slide back and forth, ensuring that the brake pads apply even pressure to both sides of the rotor. Component Breakdown Duralast Brake Caliper Bolt Guide Pin H15952 Duralast Pin Boot Kit 16116 Based on the image, the kit includes: Guide Pins (Slide Pins): The two long, smooth cylinders. These are inserted into the caliper bracket. Lock Bolts: The two shorter hex-head bolts. These thread into the ends of the guide pins to secure the caliper housing in place. Zinc Yellow Chromate Coating: The distinct gold/yellow finish is a protective plating used to prevent corrosion and rust, which is vital since these parts are exposed to road salt and moisture. Brake Caliper Guide Bolt Dust Boots and Bushings. Component Breakdown Bellowed Dust Boots (4 pieces): These accordion-style rubber sleeves fit over the caliper guide pins (or slide pins). Their primary job is to seal in grease and keep out water, salt, and road grit, preventing the pins from corroding or seizing. Rubber Bushings/Sleeves (2 pieces): These smaller, cylindrical ribbed pieces fit inside the caliper or over the end of specific guide pins to provide a cushioned, precise fit that reduces vibration and noise (brake rattle).
