need some advice. I have a hand vacuum bleeder and I cant get Grimcrapper to bleed. I keep getting a steady stream of air bubbles and there's no resistance when pumping the brake peddle. I pulled air bubbles through it for 2 hours. Is this thing leaking? does anyone know what I can replace it with or where I can get a seal kit??

have you tried syringing the fluid from the nipple to the master cylinder instead,assuming all was well with the brake at the start,this way the air ends up in the resevoir.

he said nipple....LoL no I didnt try that, but when I pump the brake peddle I can see bubbles form around the caliper puck. That cant be right

so easily amused ,not sure what you mean by caliper puck,but fluid belongs inside system so if you have bubbles outside then must be a leak,good luck, cheers.

the round piece that pushes out on the brake pad when you pump the peddle... the cylinder??? I dont even know what its called in the states and you English blokes name things differently as it is....say nipple again LOL

hi,should be no fluid or bubbles coming from the puck/piston(uk) probably seals past there sell by date,i take it fluid does come out of the nipple

YES!!!! fluid does come out of the nipple and I can't get it to stop oh well who needs rear brakes anyway

From what I understand a brembo p32f will work .

oppracing.com has the schematics for the p32f and many other calipers. good luck

What I ended up doing was i blew the puck/piston out with an air compressor. cleaned it, removed the seals lubed them and put'em back in, pressed everything back together and it bled fine. its a two person job. my brother helped pump the pedal and keep the reservoir filled while I used the hand vac. mission accomplished

bet it was a P in the A just like my rt125 rear brake bleeding job
