The seals and gaskets in your vintage SR500 calipers aren’t getting any younger. Over time, these rubber components deteriorate. As they go, they begin to leak pressure and fluid on brake discs, and they suffer from lagging performance. If you’re having to squeeze ever harder to get your SR500 disc brakes to work, this could be why. Mikes XS stocks SR500 brake caliper repair kits to sort out this common fault. We also sell SR500 front brake master cylinder repair kits and brake pads to help restore the bite to your SR500 restoration’s brake system.
