I posted a topic about this a long while ago and i had tried all the remedies and everything, even bled them a couple times.

Now that summer is here, i wanna to start doing some brake work on my bike, I'm starting of with the brakes and i was told i may need a need a new rear caliper, but the thing is what kind would i need? Which ones are compatible with A Polaris 2001 Trailblazer 250?

I have searched on eBay and just can't find anything MADE for my bike, so i was wondering if other polars rear calipers would work?

Thanks, or maybe you think the rear caliper is not the the problem? What do you think it is?

 

BUMP!

 

The rear brakes on the Polaris sport's models has this problem alot. I fixed mine by bleeding the brakes 20-30 times strait and they finally came around, that was 2 years ago and haven't lost my rear brakes yet.

 

yes, I did the same, bleed them many, many times & keep the brake
fluid right up on full on the foot resovoir, they've worked for 2 years
now on both my quads also!!

 

unless the caliper is all rusted or corrored up its most likely not the problem.i lost my rear barke on my 800 from sitting over the winter and used a heavy weight on it and left it there overnight and got some of it back. if you bleed it just remebr to not let the resiore run dry of fluid or you'll have real air problem.

 

Yea i tried to bleed them many times. and i also put 2 bricks on the floor brake overnight..


I was told to jack up the front of the bike a bit, and bleed the brakes that way, since the tubing for the brakes is up there ain't it?

 

Lifting the front will do nothing for the rear brakes.....the problem is there is a air bubble in the line.....If you follow the line from the master cylinder to the caliper you will see that it runs up the frame, then back down the swing arm to the caliper.... you can compress the rear end(strap around the axle to the bumper) then raise the rear end up 2-3 feet then bleed the brakes.
This will aid in allowing the bubble(s) to exit easier.
