I push to engage the rear brakes and nothing happens, the only braking power I have is on the front, anybody have any suggestions as to what the problem could be? It does't even apply the slightest of pressure to the disc to slow it down. Thanks

 

I took my rear master cylinder off tonight and disassembled it. The rubber seals are in good condition but they don't seem to generate enough pressure working it by hand. I think a new master cylinder is needed for my rig. Now let's see how much Polaris likes them $$$....

 

Here's a good parts link. I'm not sure how it compares to dealer pricing. Here

 

I just put my trailblazer back together and it needed a new rear caliper. Polaris has a kit for 175 and it included everything even pads and I bleed them a bunch and they work now.
