Gp Tech Handbrake Bleeding
I stumbled across a way to bleed it quick. It seems I don't have to pump the front or back first to get a good lever feel either. Here is what I did.
First made sure the rear line was bleed well, then mounted front master Cylinder, and ran line to rear cylinder, not hooking it up yet. Bleed line until fluid came out, then hooked it to the GP tech fitting, which was mounted to the rear cylinder with screw, and additional hose clamp. Here's where I think the important part is.
4 different bleedings here.
First I bleed the line from the front HB to the GP tech fitting. Do this as you would think, Pump the front HB lever and hold, brake loose the line at the GP Tech fitting, re-tighten line. Don’t let lever go until you re-tighten line. Do this until you have a good feel on the front lever.
Second. Bleed the rear cylinder and line. Pump the foot lever until you get a good feel to it. Hold it down and brake loose the line at the rear caliper still holding down foot lever, Tighten line still holding lever down reach up to the front handbrake and pump that until you feel the foot lever rise. I had to pump the front lever a couple of times to get the foot lever all the way back up. Repeat this a couple of times. Always make sure you have brake fluid in the upper reservoir. This being the most important step make sure you don’t let the foot lever up make sure it is pumped up by the front HB lever.
Third Pump front HB and hold and brake loose line at rear caliper, tighten line and repeat. This bleeds the whole system.
Forth Repeat the second step. This will make sure the rear cylinder is full and pumped up.

Re: Gp Tech Handbrake Bleeding
Whats the feel like? Does it feel like your front brake, as far as play and sesativity? (sp) Or is it hard.
I know some people that did reverse bleeds.
Pump the brake fluid from the caliper up to the master. Works really well.

Re: Gp Tech Handbrake Bleeding
I got the fullthrottle setup and for some reason the thing still seems real spongy, Ive tried everything, i think, even used a brake bleeder and all that. Any secrets to it.

Re: Gp Tech Handbrake Bleeding
I got the GP adaptor too. But instead of the hose clamp which dont work, (Schwartz trust me, curt did EVERYTHING and that didnt work), i put some JB weld on it, that should not make it flex!!! JB is some serious stuff!! Then i got a zx7 hydro clutch lever. The lever has a NICE feel to it, just need a brake line and im ready to roll.
