From small-capacity motorcycles and scooters to classics, everyday road bikes and modern superbikes, TRK covers the sort of brake and clutch service parts riders and workshops need to keep them on the road.
Old brake seals harden, flatten and collect dirt in exactly the places you would rather they did not. TRK seal kits are listed by motorcycle application and use brake-fluid-resistant EPDM rubber to give the caliper a proper refresh. Many kits also upgrade the bleed hardware to stainless steel, helping reduce the risk of a bleed nipple corroding in the caliper.
Where the application needs them, kits can include piston seals, dust seals, caliper joint seals, shaft boots, banjo washers and upgraded stainless bleed nipples. Caliper repair kits also include red rubber grease to help during assembly.
Pitted brake pistons can turn a decent braking system into a dragging, sticky mess. TRK replaces the usual plated-steel problem with stainless steel pistons designed as direct replacements for the intended application. Their corrosion resistance is one of the reasons many riders and workshops regard them as an upgrade rather than simply a like-for-like repair.
TRK is sufficiently confident in the stainless piston range to offer a lifetime guarantee against corrosion , subject to the published terms. TRK piston kits also contain the seals, stainless bleed nipple and covers, copper washers for the rebuild where available
Read the guaranteeA tired caliper is only half the story if the lever still feels sticky, slow to return or inconsistent. TRK also offers dedicated front and rear master-cylinder repair kits, listed by application and piston dimensions.
We have moved that range onto its own page so the fitting notes, sizing and safety information are easier to find.
