did wreck it ????

[sledheadrevxp]

Just swapped tracks on my xp. Now that i have it back together i have no brakes. I bled them sitting in the shop and they seem fine but as soon as it moves no brakes. Stop and pump them up and comes right back until it moves? Anyone else have an issue like this. Did i maybe bend my rotar or something. Thanks

I had a similar problem with my 08 when I had to loosen the nut on the brake line. I ended bleeding until my arm almost fell off but eventually they came back around.

They come back easy when i bleed them but go away again as soon as it moves

You have air in the system you are gonna have to bleed till your arm falls off, had the same problem with the quad. It just takes time.

i dont know why the xp brake system is such a biotch to bleed. on the rev and zx sleds its usually the second try.

I have played with it for two days. Prob have three hrs pumping the brakes up but wont stay. Like i said iy will hold over night but as soon as she moves its gone.

I'd check to see if your rotor is bent - for one reason or another........

do you have enough snow to take it for a burn? ive had sleds that wouldnt bleed but left over night went for a quick rip and voila....magic.

Make sure that the rings are installed correctly for the drive shaft bearing on the brake side. I had this happen after I installed my 2.5 on my 09, your describing the exact same issue I experienced. it would pump up good than after I took the sled for a ride I had no brakes. I loosened the drive shaft mount on the break side and turned the ring till I felt it seat the all was good after that. I bleed the brakes so many times thinking that was the issue it drove me nuts.

If it is an air in the line issue get a friend and try disconnecting the caliper, stand on a ladder and hold the caliper up above the master cylinder as high as you can while you bleed it. I use this trick on mx bikes all the time and it works great for getting out those stubborn bubbles, they naturally want to travel up instead of trying to force them down the brake line.

Warped rotor.

A hand vacuum pump with a resevoir for used fluid inline also works like a charm!

If he had the track out, pried in any way on the rotor disc, which he may have, it bends very easy. If you drive it like this it will give the symptoms he describes.

Your right. Took the brake gaurd off. Jacked it up in the shop and spun it over a few times and its bent pretty good. Anyone have a good rotor for sale??

You can straighten it easy. Remember it's only a circle of bendable metal held in place by a few thin posts. Easier than you might think.
