no brake pressure
Posted: Wed Jan 29, 2020 1:45 pm
Hello to all.this is my first post. About 18 months ago I started looking for a morris 1000 van, eventually found a non runner, which I liked, and bought it. its a 1970, and its redeeming qualities were the type 9 gearbox, sierra front brakes and 1275 engine. After a lot of work got it running, connected gearbox hydraulics, repaired the wiring loom, so it starts and runs, but brakes have turned into a real pain.
I have fitted new master cylinder, servo, new rear cylinders, front pistons and seals, brake pipes etc,( master cylinder has had rear seal removed), but I still have to pump the brakes to get any pressure. There are no leaks, and no air in the system,and still no brakes.
I have bled the brakes countless times and still zero.I have read many posts on the forum,and have tried some of the advice given, but I am running out of ideas.Why, after pumping the pedal maybe 10 or 12 times is there pressure on the pedal,but take your foot off and then reapply, and the pedal goes to the floor?
It has a remote reservoir,should the master cylinder be full, or should there be an air gap?
The disc pads are new, as are the discs, meaning the major part of the piston is inside the caliper, would this make any difference?
If there is somebody who could offer some sound advice it will be much appreciated, and before any one suggests it, yes I have tried wedging the pedal down over night and it has not worked.
So I have a great looking van that serves no practical purpose at the moment,next stop, the most expensive chicken coup in wales!
Look forward to your advice.
