1998 Polaris Sportsman Master Cylinder Leaks

I am having an issue. Replaced front and rear brakes on a 1998 Sportsman. After bleeding the brakes, I only get pressure to front and rear brakes when I press both rear and front brakes. When I do this, brake fluid leaks from the lids of the rear reservoir and/or the front master cylinder reservoir due to back pressure. Any ideas to what is causing this?

Hey Hutchinson,

Not sure if this could be possible but can the two hoses on the rear caliper be switched? I read up on the breaking system in my manual and it looks like the rear caliper has two ports, dual chamber. When the front brakes are applied it also puts some pressure to the rear as well. Maybe with them switched the flow of brake fluid is reversed somehow. Just a guess on my part!

i had the same problem with mine, when you bleed the brakes did you constantly add more oil in the reserve because mine did that and when i filled it up, capped it and bleed them again it stopped. it was making a hell of a mess all over the atv and the garage floor
