Hi

I have searched and couldnt find an answer. I can't get any brake pressure after i did a rear disc conversion. when trying to bleed no fluid comes out but i can feel resistance from the master cylinder. When trying to bleed them the reservoir doesn't go down either.

Please help

 

You are having someone pump the brakes a few times, have them hold the brake down as you open the schrader valve right? If not you're not going to get anything done. Sorry, You didn't specify what you already tried so I'm making assumptions here.

 

Yeah someone on the pedals while i man the valve. I've bled brakes before. I just don't know why they won't bleed now.

 

help

 

Disconnect one of the lines from the caliper in the back to see if it is getting any fluid first. then work your way forward from there. If you are using new lines, make sure that you removed any plugs before install.

Another thing is if your messed up the diaphragm in the MC from your buddy pedaling to the floor while you were trying to bleed.

 

Thanks man, I think some fault finding is in order.
