Unable to bleed rear brake.

[oport]

Thank you all for your advice, problem is solved. Since i decided for safety reasons that this problem has to go completely, my garage fitted new pads and hoses all around.
The problem was indeed a little piece of rubber from the hoses. That little bugger was blown out and everything is fine again...

Evening,

being a source of constant torment to myself, I have decided to rebuild the complete braking system on my 2000tc. I have redone rear calipers and hoses, the fronts are in the proccess of being replaced, I now need to remove the master cylinder.

The question for the day is.... How do you remove the master cylinder from bulkhead of the car. It looks like a pretty un-user friendly job as with all jobs involving the p6's brakes, however, the brakes are bolted through to an area of the car I can't seem to reach, so all that happens is the threaded stud just keeps on spinning.

also.... I imagine you need to remove the clutch cylinder to get at the master cylinder's lower nut, allowing you to remove this, can anyone confirm this or am I making a relatively simply job more complicated?

If the mounting stud is spinning it must be stripped in the bulkhead, so that will need retapping or repairing in some other way (helicoil) once it's off. I've never removed the clutch master cyl to gain access to either bolt. To get the spinning stud off you will need to remove the other nut, and the pushrod inside the car, and then pull the m/cyl out as you turn the stripped stud whlst doing so and it should pull itself out.

Firstly, Cheers Harvey, you can indeed get the cylinder out without taking the whole car apart.


Right, cylinder out, dismantled and rebuild, though I haven't changed the seals over, as they looked pretty decent to me.

HOWEVER.... Once reassembled the cylinder the inlet hole from the reservoir doesn't seem to be pushing the brake fluid through to the secondary hole to pump to the slave cylinder/servo unit.


The rear rubber seal appears to be sticking, preventing fluid from entering the cylinder, and therefore being pumped further through the system.

The diagram on the Rover Owners Manual is different to the actual cylinder I have also, the larger seal is placed further forward in the cylinder, is this right?
