Ok, I have helped buddies bleed brakes on a car before a couple times and it never took much time at all. However, I got a hb setup from a member on here, GP tech fitting, line, and maqura master cylinder. I got it all hooked up etc....and dug up some old posts and talke to a friend. Long story short I worked at it for at least 2.5 hrs with no progress.....handbrake is MUSH no pressure nothing. I squeze the master hold it in, undo the nipple thing and barely anything comes out....keep in mind i had been doing this and repeating over and over again with no pressure EVER building up. My buddy told me to constantly depress the foot brake pedal the whole time while doing this....

Can someone please shed some light on my retarded ***. I gotta get this bike up and running before saturday.

Thanks

Mine wouldnt bleed unless i tilted the master proper, not upside down but once it was bled it didnt matter. So take it off the bars.. tilt it right i even kept it up in the air so the line went straight down.

 

everyone of my hb's that me and my friends have bleed, I always put it on upside down(like its going to be used), fill up the reservoir with fluid, and hook up my vacuum bleeder....makes it super easy, you'll have pressure in about 3 or 4 minutes....then to play it safe, after it gets pressure I'll do the old school way. Pump, hold, turn the bleeder screw, repeat on foot brake, then back to hand brake and your done...

 

+1 Thats my way too.

 

you can try reverse bleeding it with a seringe thats what i did when i couldnt get al the air out off the line. now its stiff as a rock brake works perfect now

 

try and bleed the all the banjo bolts,starting from the hand lever,that should do the trick

 

i do all that, then take it right side up and pry the brake pads open (pushing the pistons back into the caliper) which forces fluid back up the wrong way in the system and pushes out any bubbles trapped in the master. this works perfect for me every time.

 

+1

basically them same thing i said lol best way to do it

 

 

What usually works for me is to open the bleeder(s) while filling the system and when a steady stream starts pumping out then close them. You would be suprised how quickly it will fill up and you won't have any air in the lines. That usually gets me close, then its a matter of fine tuning with the master cyclinder.

 

i had someone else tell me that too

been trying to bleed my buddy's **** for a week, once i figure this here bitch out i'm gonna put mine on

 

im too lazy to read everyone else's post. the way i did mine, was opened up the bleeders when i filled the lines, mounted the HB master on the RIGHT clip on, so it was all facing up right, bleed the rear master(i have two bleeders) then bleed the rear caliper, bleed the rear master once more, filled up the reseviour, then unbolted the perch and put in on the left clip on without unbolting any of the brake lines obviously. the first time i did it, i was an idiot and got brake fluid on my pads, which totally destroys brake pads and makes it feel like you have air in the lines....so just be carefull not to get any fluid on the pads(from bleeding the caliper) and then not to get any greese on the rotors cuz that will just get into the pads too.

best of luck

 

My buddy told me to hold the rear brake pedal down the whole time as im pumping the hb master. I guess maybe i have no clue what im actually doing....I have a mangura master cylinder...looks like a clutch side master cuz i have it on the left clip on and the resivoir sits right side up. Anyway, the line goes into my rear master and then the GP tech fittin goes to the rear caliper. What is teh exact process I should go through in order to bleed this **** out....do you have to bleed the handbrake and foot brake?? or do you simply leave the foot brake alone??? I'm very lost lol I spent anotehr hour or so last nite after my post ******* with it...STILL WITH NO PRESSURE!!!!

Right now i have a wieght depressing the foot pedal, I pump up the master a bunch of times (never builds pressure) and then i squeeze it in and open the bleeder....OCCASSIONALY a very tiny amount of fluid will ooze out, but nothing mroe ever happens and it NEVER builds any pressure.

I'm really sure that somewhere along the lines I'm a complete retard, but I really have no clue whats going on here or why its not working. Maybe my lack of knowledge of how the system works is why im fucknig this up.

Thanks for your patients guys

It is easy to bleed , take the cap off and keep pumping till you feel lil bit stiff then take 8mm wrench for the rear caliper to bleed it out then tight it back do the same again and again ...sometimes it might takes 15 minutes to do this.

 

haha man i tried doing that for like 2.5-3 hrs yesterday....theres gotta be something im missing....are you supposed do anything with the brake pedal on the foot brake?

 

first of all take the weight off your rear brake .........

when replacing or adding new lines there will be alot of air in the system so just open the bleeder and leave it open, let it gravity bleed till fluid is dripping out of it if it wont gravity bleed then just pump the hand brake till you get fluid pumping out of the bleeder then simply place your finger over the open bleeder and pump the hand brake ,your finger will let the air and fluid out but wont let the air in........

when it is just pumping out solid fluid and no air you hold the hand brake in and then you can take your finger off the bleeder and tighten it

if the hand brake feels too soft then bleed it some more

and if you do get brake fuid on your bads just wash it off with water ,as long as you dont let the fluid sit on the pads too long it wont hurt them

 

The line from the master should go to the fitting, the rear line should be in its normal location this could be your issue. GP Tech fitting goes to the master/resv not the rear caliper.

 

good eye .........

i didn't even noticed he said that

 

I dont know why he would have done it, I hope its a typo but if its not fix that first!

 

That was a typo but thanks alot guys!!! I will try this when i get home today.... GP tech fittin is in the proper place and the rear caliper fitting is in correct place as well!!
