Brake problems

Postby geo steinke » Thu Jun 17, 2010 7:59 am



I'm working on a 81 wing that has sat for a long time. The brakes were empty so I added fluid and tried to bleed the brakes off. I get a little trinke of fluid out of the bleeders put there is no pressure there. Are there orings on the plunger that need to be replaced? This is on both the front and rear brake systems.

Yes there are o rings..but lots of other things in a rebuild too..both masters have two holes for fluid movement you must find and clean both, lines can collapse, bleeders rusted shut/clogged, piston stuck in place..pull everyting apart and clean/rebuilt..brakes are something you don't want to fail.

My brakes worked but chose to do a brake job. I can't seem to get any pressure to build up.

Sounds like lots of air in the lines. I like to fill my brakes from the bottom up eliminates most of the air in the liens problem. Start at brake furthest anyway from the master..loosen bleeder, attache clean hose, attache large syringe(get on from any vet or farm supply store) fill and pump fluid slowing up through the system this will push air ahead of the fluid up and out..repeat on each caliper..a little pumping and bleeding if any is needed to set the system.

Another option is to tie your brake lever open and let it sit over night or a day or two..every time you go by the bike tap the lines.to help the air along..the more tapping the faster this will work.

you could always just wait and try to win the mighty-vac system at the end of the month, then you'll have the perfect tool for the job! :lol: :lol: :lol: :lol:
    You only need two tools in life - wd-40 and duct tape. If it doesn't move and should, use the wd-40. If it shouldn't move and does, use the duct tape!

Mity-Vac is the way to go!!
I already had one, so I didn't have to win one... fill the reservoir, and attach the mity-vac (with the capture bottle between the vac and the caliper) and just start squeezing the trigger.... within a minute or two even a completely dry, brand new brake line will be filled with fluid. Just make sure that you keep an eye on the master cylinder so you don't drain it before getting fluid down to the calipers.

After line is filled and caliper has fluid in it, the capture bottle will allow you to pump 'em up and crack the bleeder screw a few times to insure all the air is gone, the fluid already in the bottle will help prevent air from returning to the brake system.

Until I got a Mity-Vac, I hated bleeding brakes. Now it's almost fun! :)

i have a problem with my brakes too. i pull the lever and i get light brakes, release and pull again and i have more brake, bled the heck out of the thing(about 2 large bottles of brake fluid) and do not get any more air.
do you think the lines expanding from age would give this symptom, or do i have a trapped air bubble somewhere i cant get out?
