Brake Seal Kits: the small parts that keep a caliper holding pressure
Brake seal kits are the piston seals, dust seals and banjo bolt seals that let a caliper build and hold hydraulic pressure without weeping fluid. When a caliper drags, a piston sticks, or you spot fluid seeping past a bore or a banjo fitting, fresh seals are usually what brings it back. Fitting one is a rebuild job: strip the caliper, clean the bore, seat the new seals square, and bleed the system. Done right, it restores a firm lever or pedal and stops the slow fluid loss that ruins pads and rotors.
The first decision is whether you need a complete seal kit or a single seal. A full kit like the Performance Machine sets matches a specific caliper model, so it carries every seal that caliper uses in one box. The Brembo items are individual piston seals sized 34mm and 38mm, which suits you when only one seal has failed and you can identify the bore size. Banjo bolt seals, sold in a 10-pack, are a separate wear item at the line fitting and are cheap enough to renew whenever a line comes off. Because seals are caliper-specific, matching the part to your exact caliper matters more than brand loyalty here.
Fitment data in this category is limited: one product lists application detail, covering Harley-Davidson XL models across the 1979 to 1981 year range. Treat brand and part numbers as your guide and confirm the caliper before you buy. If you are unsure which seal your caliper takes, call fitment help at 813-535-5801 or reach us through contact us. All orders ship free, and Affirm financing is available through our financing options.
