Cant get any brake pressure....please help

[Snowmobile Kid]

I cant get any brake pressure, I bled out my line and there is fluid running out but when I pump the brake lever the fluid goes down in the resivoir but then comes back up. does this mean there is an air pocket somewhere or is my master cylinder just shot? any ideas?

Take the caliper off and push the piston/piston's all the way back in
This pushes all the fluid out and back to the master and hopefully the air too
I always burp the banjo bolt's too
For the future
Fill and bleed the master before you even put the hose on (use your finger)
Put the hose on and fill it holding the caliper end up above the master
Then fill the caliper with the piston pushed all the way in, some guys clamp it
Bleed as neccesary

then what is the purpose of the bleeder vavle

i had major problems bleeding my brake system on my 03 edge 700. i spent an hour trying to get any pressure and nothing. i ended up letting it sit over night, went back out to it and just tapped on the brake line and air bubbles were coming out non-stop, care barely keep enough brake fluid in the master cylinder.

i'd let it sit for a while and then see if you can make any progress.

Try this, turn your handlebars full right. This will usually put the master cylinder on an angle with the banjo bolt side facing downward, which is what you want. Now kind of tap the brake lever, not squeezing but just barely applying and then letting go repeatedly and quickly. This wil get any air out of the banjo bolt area. Depending on the cap you may be able to see the bubbles. If you can't get the right angle just by turning the bars, tip the sled slightly. Make sure your reservoir is full first. This will almost always work if there is air trapped there.

put a wrench on the bleeder.....put a piece of clear tubing on the nipple of the bleeder......put the end of the tubing from the bleeder into a pop bottle or any container to catch the fluid...add a touch of fluid to prevent the line from pullin air back up.......open the bleeder while leaving the wrench on the nipple.......fill the resivor......pump....fill.....pump......when the air stops and you have clear fluid, close the nipple before removing the tubing.....done. its totally fool proof and you get clean fluid to boot.

if you use this on cars start farthest away from the master and work closer.

Or if you can get your hands on one a vacuum fluid extractor is the best, maybe if ya got a buddy who is an Auto tech. he will have one, above suggestion is the next best thing to do!!!!!

Some real good tips in these 2 posts.

I had a Mtn Max once that almost made me pull my hair out trying to bleed the stupid thing.

I always use tubing and just hold it over the reservoir and keep pumping. That saves me from having to refill and I run no danger of pulling air back in though the hose. On cars and trucks I use a bottle and keep a dip in the hose. Always try to get the most done with the least amount of effort!

that is a good idea...might have to add it to my arsenal if'n ya don't mind

I have a mighty vac but find the tubing easier simply because the mightyvac resivor is only a couple ounces.......but it works like a dream, just a lot of dumping.

Brakes

If You dont have vac bleeder use hose that will fit over bleeder longer the better take cap off top, open bleeder on brake cal. fill hose with fluid use low air psi or blow in hose with mouth push flluid up to res.dont let hos go dry . clear hose works best .

I use a clear tube on the brake bleed nipple, top off the brake resevoir, pump the handle slowly three times, hold, crack the bleeder and let fluid escape. close bleeder, pump three times again, rinse repeat. I've never had it fail except when the master cylinder was completely shot and needed a rebuild. Don't forget to top off the master cylinder as well.

I've had to do emergency brake caliper replacements at the track with a superbike a few times and never had the above proceedure take more than a couple minutes to complete (and the rider never complained about how the brake felt afterwards
