Range Rover brake system problem

[GURU]

G'day all,

I'm having a problem with the brakes on my project 90, which uses all Range Rover brakes (around 1982 components) the only differance is I have fitted the Servo and Master cylinder to a Series III brake pedal assembly.

Now this is the problem I have, the Primary system has air in it, but the secondary system seems to have no air at all.

Whats the trick to bleeding the system?

Use a power bleeder.

Or lazy like fit bleed screws with one way valves. ( they work great)

G'day all,

Well I have found the problem, but not the cause. My Primary system just won't bleed, when I disconnect the rear brake line from the flex hose, very little fluid will pump through, when I say little, I mean bugger all.

Does this mean my MC is leaking in the primary part? or is there another problem ?

Have you used the rangie "brake failure valve?" It might be locking of the primary due to the lack of pressure! I am only a hack and probably wrong (disclaimer!!!!) but try opening a bleed valve on the secondary system and see what happens to the primary. I think from memory you are supposed to blled both at the same time but theres a good chance that I am making no sense.

Silly question..... Does the pedal travel far enough to activate the master cyl????

Yes it does as the rig stops on the secondary setup, so that system is working fine
