Braking Help

[jaywalker]

hi guys i have a problem with my xe nova gsi brakes:cry: , i have put on brand new rear drums with all new internals, bled the system as said in haynes,
put it on ramps, axles stands and checked for all leaks and everythings fine ,but the pedal still goes to the floor.
the handbrake works fine and the servo,
a guy i know said the master cylinder might be the problem?
any ideas please
the front brakes are astra gte jobbies, std gsi set up on rears

also if i were to change the servo & master cylinder can i uprate to a gsi,cav,calibra set up?, or is this not advised or to hard to convert

any advice would be much appreciated:thumb:

well if you wanted to use a cavalier one the mechanism that pulls on the back of the servo is oppiste to the nova one but you can just cut it and weld it, there is a guide on here made by rich somewhere, but there not expensive to replace the original part
