Hello
I just purchased a used 250r it didnt have any front brakes. so i bought a used master cyclinder, hose, caliper, brake pads. I am tringto bleed the master cyclinder but it is not pumping up with pressure. I see bubbles comming up thought the fluid and when i break the line loose at the master cyclinder nothing comes out. The guy i bought it from said its a pain. Can anyone provide any pointers on how to bleed system?

p.s. can i gravity bleed the cyclinder?

thanks

 

AAAAHHHHH, welcome to my world of OLD brakes. I almost drove myself crazy with this. You are going to have to take the plunger out of the master cylinder. There is a tiny hole that the fluid comes out of and it's probably clogged. You can also try and use a vacuum bleeder. You can pick one up at an auto parts store pretty cheap(a hand pump one).

 

thank you. looks like that was the problem. and now i have brakes. lol
thank you very much.
