Hi, I had a ceased caliper on and off for a month or so and i finally got round to unceasing it with my mate, we got the piston to move in and out without much pressure so we got that far, When it came to putting the calipers back on we bled them all but then found i had no brakes??

Ive been and tried a second hand master cylinder today but it had no effect, infact it made it worse because it would suck air in between the cylinder and the servo.

Is it worth buying a brand new cylinder and servo?

Joe.

 

what car? could it be the flexi pipe?

 

Could have rotten fluid still in the pipes blocking the fluid from getting through ?

 

sorry its a S2 rst..There is fluid coming out the nipples and no air coming out, its almost like im loosing vacuum or something?

 

if you were losing vacum joe the pedal would go hard i think

 

In what way do you have no brakes? Does the the pedal just goe straight to the floor? If so, and your sure you've bled the system properly, then your MC is probably shot. But if your losing fluid between the servo and MC then that won't help either.

Chances are when you bled them the first time on the original MC, you turnt the seals back on themselves, since the the piston never normally travels that far in the MC.
