Brake pipe bleed points

Can anyone give advise please, putting together new brake pipes and ancillaries on a diff after strip down and rebuild, re made short bent pipe connecting the two rear cylinders as per pattern, but didn't fit when reassembling as per the way I would have expect it to be plumbed, checked pic of diff before strip down and it was not originally plumbed as I would have expected either, fluid "in" was to top port on both cylinders!, I would have expected it to go into the bottom port, thus allowing air to be pushed out through the top bleed point or onto next cylinder. Has the pipe been assembled incorrectly in the past or is this how they were built? DSCF5096.JPG

That's how they're supposed to be. I noticed you had the bleed nipple in the wrong hole in your previous pic, but I thought you'd find out later!
ok thanks,, i will rebuild as pic above then, also means the short pipe i made will fit and not have to remake it, still does not seem logical, but there must be some logic to rovers design.

I believe, and may be wrong, that the bleed screw is in the lower hole as it would be impossible to reach it to bleed the rear brakes if it was in the top one. especially as the brake pipe will be in the way.

Yep, and people moan about how difficult it is to get at the bleed nipple and bleed them with the nipple in the lower hole as it should be.....

On the other side, if the hose from the base unit goes into the lower hole, with the correct hose, it gets very close to the disc.

I didn’t know about the other side but did have somewhere in the depths of my memory about the lower bleed nipple. I don’t have that problem now though as my rear calipers are a lot easier to get at.

Hi, You could always replace the bleed nipple with a pipe or flexible to bring a bleed nipple out to a more convenient location.

Hi Richard,

My Rover has the bleed nipple in the wrong spot, been that way for as long as I can remember. Luckily I have a 7/16" spanner that belonged to my Dad with a very noticeable offset and that means I can access it without too much difficulty when laying on the ground. When the time comes to overhaul the calipers again, I'll swap their positions.

Ron.

I never had any trouble bleeding the rear calipers, but you have to wonder at Rover for putting both inlet pipes at the top. OK I can see the inlet pipe on the OS being close to the disc, but better routing would surely solve that. No reason why the pipes cannot be swopped over on the NS.
This would aid air removal, but I guess putting the bleed nipple at the top would make it even harder to get at. But then H likes having fun, so he could be P6 bleed agent, or - that bleeding H, or H the bleeder ?

I don't think the location of the bleeder makes any difference to ease of bleeding. There is only a couple of cc's of fluid volume in these rear calipers, and most of it is the passage drillings, so there is not really any corners to trap air.
