Iv been trying to bleed my front brakes iv tried everything with bleeding they wont build pressure someone help

 

do it right...........

 

pump em maybe.... see if that works

 

thanks i did what voughn and dubc told me to and nothing so thanks for the advice goo your the best

 

how are you bleeding them?

 

do the far one with a hose sumerged in fluid rapidly pump and add fluid to to master three times then tightn do same for other side then olld fashion squeez tightn let out over and over well iv been doing this for three days now and i need this for a show sun

 

Easiest way is to get a small syringe and put a hose on it and fill it up w/brake fluid. Then open up the bleeder screw on your Caliper and put the hose on the bleeder screw and fill it full of fluid backwards until the mastercylinder reservoir is full of fluid and you dont see any bubbles coming thru. Then you can just pump the brake and bleed it the normal way to get the remaining air out of the lines.

Ive always had good luck w/this method. Just put a handbrake on my F4i and bled it with this method and it took maybe 15mins and it was done.

 

Do you have 2 seperate lines or is it have one main line to the right calper and then a connecting line from that calper to the other?

 

^^^ i do, i have the same prob...the master has great presure but the brakes wont grab ???

 

two lines one down one connecting 636 stock lines i put a 636 front on my f4i everything is good but the clipons and no brakes i got clip ons overnighted

 

they have bleeder, im not sure how much they are, you put this littl nozzle thing in the bleeder and it takes all the air out... worked for me

 

If you can't build pressure, your piston inside the master may be corroded enough that it will not retract after you pull your lever. If you believe this is the case, hit me up and I will walk you through the fix over the phone or I will fix it for you. No parts to buy, just some time to completely dismantle and douche the master.

i have 1 line to the right caliper and from that caliper one line to the left caliper....why dont i have brakes???? the master has pressure

 

Easily diagnosed...
I would disconnect the line from the maser and make sure it sends fluid when you pull lever. If not, it's clogged somewhere and will feel like it has pressure. If it does send fluid, reconnect the line and disconnect it at the caliper. Check the other end of the line for fluid when you pull lever. If you have fluid there, the line is fine and the problem lies in that caliper.

 

ok so take off the line,put banjo back in master and squeeze to see it fluid comes out..??

 

Doesn't matter if banjo is back in or not but that's where I would start.

 

cool thanks man...ill try it when i get home from work

 

Yeah take off the banjo and put your finger over the hole and squeeze the brake.. If it pushes fluid passed your finger the master is good.. If not the master is crap. I tried putting my old 636 one on my bike and it wouldn't push fluid passed my thumb..
