What are the pin boots on a caliper?
“Pin Boots” are small tubular, ribbed rubber components (red in the picture) that snap into grooves in the slide pin and also the fixed caliper bracket. Their job is to keep the water, sand and dirt away from the slide pin bores and helps keep the special grease inside. When pin boots don’t keep the bad stuff out anymore, the pins can seize.
What do you need to know about pin boots?
These pins are greased and allow for proper alignment of the caliper to the brake rotor and still allow for the movement needed under normal driving. “Pin Boots” are small tubular, ribbed rubber components (red in the picture) that snap into grooves in the slide pin and also the fixed caliper bracket.
What causes a caliper slide pin to swell?
One issue is how grease impacts rubber seals. A caliper slide pin has a rubber boot that seals out dirt, and often has a rubber bushing for movement and support. If you’re not using silicone or PAG, these rubber parts can swell. [For more, check out Larry Carley’s article on Brake & Front End).
