brembo master cylinder help...
got a brand new 04-05 R1 brembo master cylinder... trying to use it for my handbrake...bled it right side up and it works fine, as soon as i flip it upside down it goes spongy.... i bled it for two hours from the master cyclinder and the caliper.. still spongy, but then i flip back to right side up and rock hard...
anybody know anything about this or know what's going on..?

Ive installed the same master for a friend with no problems, I actually really like that master.....Plain and simple you havent bleed it good enough, either keep trying or have someone better at bleedin do it for you....Theres no way you should be spending 2 hours bleedin it, 1/2 hour tops if your good at bleedin..And Ive never used a vaccumm, its not needed at all

Re: brembo master cylinder help...
im bleeding it from the actual master cylinder, than i bleed it from the rear caliper..... i guess ill try again and just keep bleeding and bleeding and see if i can get it to harden up... i just started to think that something mechanically wouldn't allow the master cylinder to be used upside down....
thanks for the input guys,
appreciate it...

Re: brembo master cylinder help...
real simple, keep the resi above the damn mastercyclinder which means Relocating it, hold the master above the bike in mid air and have some one hold the resivour while u turn the master cyllinder each direction pumping it furisouly till all air bubbles flow out into the resi, make sure to have the cap off while u do this. bleed it at the banjo bolt to when u mount it to the clip-on squeeze that damn lever n crack the banjo bolt and so on.. don't be afraid to bleed it.

aight... ill give that a try too.... i've been using handbrakes for 2 years now and never had any problems bleeding them except for the 954s,929s and now these... they both do the same thing.... but ill give the suggestions a valiant effort and see where i land...
