Still not finished these fekin brakes. After replacing the master cylinder with a complete new unit, it now seems to refuse to want to bleed.

Filled it up and open all the bleed nipples to let gravity do its job (with a couple of pumps of the brakes, then locked them all off apart from rear left and tried to bleed, but not much luck. Then tried locking off and bleeding each one in turn, without much luck either.

Tried using pressure self bleed kit, but it seems to pressure up and then go no further. I'm assuming that I have an air lock, how best do I tackle this, or should I just buy a new Landy!?

Cheers

I usually bleed them at the pipes on the master first.

how does your pressure/self bleeder work so I get some idea what's happening.

Do them things have a load sensing valve on the rear, you have it jacked up and it's shut off, or its fooked.

If it's got one find the pipe that feeds into it and bleed it there and then see if it bleeds on the outlets. If it's the lever plunger type move the lever and see if the piston is siezed.
 
Hi,

the pressure bleeder is fitted to your tyre, this pipe then goes into a single container which is filled with brake fluid. Another pipe then goes to the master brake cylinder, fluid is forced through the master cylinder, through the brake system and forces out the fluid to whichever bleed nut you've opened. So , at the moment, its pressuring up, but no fluid is bleeding out through the rear passenger bleed valve. Can't see why not unless I have the mutha of all airlocks.....

Ok thats similar to what we have in the garage. First whilst it's under pressure release the cap slightly until the fluid leaks out, thats the master bled of air, then crack off each off the pipes on the master and you are finished there if it ****es fluid.

Next track the pipe lines to the rear and see if there is any other valves, load sensing valve and crack of the pipe leading into it, then out of it, then it goes to the wheels, heh presto.

I get a feeling there is a load sensing valve on the rear shutting of yer fluid, I think I mentioned this the last time.
 
Where is CharlesY??

and more importantly, star wars joke

What's "Yoda" short for???













Coz he's only got little legs:D:D
 
Magic, thanks for that. I'll have a look for this load sensing valve, he might be the key to this. But first off, as you say, I'll crack the pipes that lead off the MBS, till they pish fluid and then get on with hunting down the valve, or if not, bleeding the brakes from the rear left.

Thanks for the help, don't know what I'd do without the forum!
cheers
