My 1980 4/4 has a hard brake line that runs directly to the right side rear wheel cylinder, and then a second line that connects from the right to the left. I haven't seen such a roundabout connection before - and while I know the hydraulic fluid may not care (if it's bleed well) - I'd expect a brass T over the axle and separate runs to each side (with a bleeder on both side) might work better to get the air out of the system. Was this a previous owner getting creative when they lost parts, or was this an actual MMC setup for this car? I can add a T and make up new lines to both sides, but I can't believe this was the factory set up. Thanks in advance...Logg.

Should have mentioned there is a flex hose before the axle - it's not hard pipe from frame to axle as that would obviously cycle and fail. Should have been more precise with my words. Logg

My .'72 is the same as above with a T piece, but in my vague collection of memories, I'm sure I've seen a set up like yours with a hard link pipe between rear cylinders. so it may be a factory fit.

I have seen early cars plumbed in with both methods from MMC.
The T-piece is a better system for bleeding , but both will work well, especially if you have a "power bleeder" .
If it worries you , then plumb in a T-piece , but if not continue to drive on your current system and make a note to convert it when you do a rebuild , or other major work.

Thanks to all for the info - I've never seen a series connection from cylinder to cylinder but can power bleed for now. A "T" and new lines over the axle go on the "list", but not at the very top. Logg
