Does anyone know if the rear brake master cylinder for a 99 Sportsman 500 can be rebuilt or does the whole cylinder need to be replaced. Thank you.

 

This system is sometimes hard to bleed,a Mity Vac or similar brake bleeder might help,but if you're sure the master cylinder is bad or if the seals are leaking it has to be replaced. Not cheap,so make sure you eliminate any air in the system or caliper problem.Item#18. Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse
