My foot brake does not work on my 700. It goes right to the floorboard without any intentions of working.LOL

What do I need to look for to fix this problem?? I like having a foot brake when I need it even though I don't use it that often.

Thanks in advance.

I had a 2004 700 and the foot brake worked on it for about the first year and then it started getting weaker till it finally didnt work at all !! I heared that they had trouble with the rear master cylinder and that their was a few quick fixes like putting a brick on the foot brake overnight I tried it and it didnt work just like all the other ones !! The only thing I know to do is get a new master cylinder !! People told me the reason it didnt work was because I didnt use it enough but the 2004 sportsman you had to put the rear brake on to get it to go into high range and reverse so I used it plenty !!

I just had mine go out on my last ride also, I have not had a chance to tear into yet but when I do I will let know what I find.

I've had four of them go out on my SP800. Two were replaced under warranty, I replaced one myself (back when Ridgerunner sold the parts cheap), and now that one is dead too. So I have one out of the machine to play with if I ever remember to dig it out and see if I can disassemble it...

had this issue on my scrambler was told by the dealer that the master cylinder had blown a seal I spoke to some friends and they said that was hard to do try bleading the brakes, so I did and works good as new so try that.

I've been too lazy to mess with the brake here lately. Maybe this weekend.

Since I'm riding the Rubicon Trail this weekend with some friends, I had a renewed interest in my footbrake.

I pulled the original out of a box and was examining it. I couldn't see how to get it apart, but there's gotta be a way. I decided to try swapping back onto the quad just to see what would happen.

So I did... and started pumping the pedal, checking the fluid, to see if it went down. It did a little, then stopped. Then it dripped a little from around the plunger, so I think the seal on that one is bad.

So I picked up the one I just removed and pushed the plunger and just missed being hit in the face by fluid. Hmmmm..

I put the old one back on again. This time I hooked up a plastic line to the rear brake and cracked the bleeder. I added more fluid and pumped. And pumped. And pumped. And added fluid. And pumped some more. Finally when I saw no more bubbles in the plastic, I closed the bleeder. I added a little more fluid to the proper level and closed the cap.

Then I tried the pedal. FIRM!!! Holy cow. Did I just fix my rear brake???

So we'll see. I didn't put the rest of the quad back together; I'll wait a day or so and see if it bleeds down.

Mine doesnt work that well either, I am not so sure that Polaris designed it to "work" as well as we all think it should. I think they wanted the hand brake to be 98% of the brakeing input.

Thats just my two cents, could be wrong, I have been before.

Mine's been holding nicely since I bled it. Granted it's stopping power is only so-so (it only operates a single brake, after all), but at least it's there.

use the 'brick' trick to get your foot brake back, take a brick or other heavy weight and put on the brake pedal and leave it overnight, then pump up brakes in the morning and they should be back

Question

So my rear brake works on my 2007 Sportsman 800 but only when I used the hand brake, is the handbrake supposed to activate all three brakes? I replaced the master cylinder with a cheap aftermarket part, then blead the system, then refilled and got all the air out of it. So why is it still not working?

Yeh fellers a guy is also having problems with his rear brake on his 2002 Polaris 325 trail boss. A guy went a blend the brakes and thought that would get rid of the problem, but it didn't. I might change the line to see if that changes the problem, but I know the line isn't clogged because the foot brake doesn't fight me. What would be a solution to fix this?
