I sent em an email to see if everything would work with a brakeline and be able to use brake fluid instead of mineral oil like some clutch masters.

 

anyone wanna help me figure out what i'm doing wrong bleeding my handbrake?

 

you're a lil far away for me to look at it, but I'm guessing you got air in the system somewhere!

heres a simple way to bleed your brakes.......make sure your handbrake master is facing the way it was originally meant to, so front brake masters should be facing the wrong way on your left clip-on, next get a 1/4" hose to stretch onto the bleeder screw and make it loop up so you can see the bubbles come out of the caliper and gravity keeps the air from having an easy trip back into the bleeder screw, then keep feeding the handbrake master brake fluid, pump up your handbrake and hold it, have someone crack open the bleeder screw to let air out then close it, now release the handbrake lever and pump it up again til theres pressure and repeat......when theres no more air coming out of the caliper you should be good to go, pump up the handbrake and it should stay pumped, and you shouldn't have to pump it to switch from your foot-brake to your handbrake if you're running a single caliper set-up, remember to not let your reservoir get empty. If you have to pump it, you have air in the system somewhere....rear master cylinder, front master cylinder, GPTech adaptors can flex and let air in too. If you have air in your rear master your handbrake master prolly won't want to bleed either, you can bleed your rear master the same way by using your handbrake master as the reservoir for the entire system, just don't let the reservoir run empty. There's more tricks for bleeding the master cylinders that don't have bleeder screws like the new radial masters.

Hope that helps.

 

i know i have air somewhere. but looping the bleeding screw to the resevoir will help a lot. let's just say that the ground around where i currently park my bike at my dorm; has stains all around it.

 

When you bleed your setup, bleed it at EVERY junction

First bleed it up at the master cylinder on the handle bar.. Unscrew the banjo fitting a little to bleed it at the banjo

Then move onto the juntion valve that goes into the rear master, losen the banjo again down there and bleed it real good

Then move back to the caliper, bleed the banjo on the caliper really good
Then finally bleed the calipers bleeding screw


I did this on my f4i the first time, took about 10 minutes, and there is NO pump up between the foot brake and hand brake.

 

I had a bitch of a time with mine until I put some teflon tape on the bleeder screw on the rear caliper and then it worked first try.

 

teflon tape, huh?

 

yeah, you know the white tape you use on air compressors to prevents leaks... just wrap a small piece around the threads on the bleeder screw. Dunno if that's where your problem is but it worked for me.... What method are you using to bleed ? pump, crack, close, pump? or covering the nipple with your finger or piece of clear tube and pumping? or do you have a vaccum pump?

 

i bleed my front brakes to be the ****...but anyway, i was originally pumping and building as much pressure as i could; squeeze and hold, crack open and close real quick, repeat. then i just tried to hold my finger over the bleeder with the bleeder screw just barely open...same results. im sure theres some huge air bubble somewhere in the line that my dumb *** cant bleed out. when i get some more brake fluid, ill try the hose looping the bleeder into the resevoir, that sounds like itll work well. never used a vaccum pump...they work well?
