Lines from MC/H-block to rear axle are done. Started rear line at rear axle and went forward to union under middle of car. Used the old line as a template and installation was easy.

Then started front line at MC/H-block down to union with rear line. Fitting the line required installing/uninstalling the line many times for measuring, bending, checking fit, etc. I removed both water lines to heater, speedo cable, and throttle cable to make fitting the front line along the front of the heater and down the firewall and under the car easy.

The two lines on the rear axle and the two on the front crossmember will be much easier in comparison.

UPDATE:
Done. All brake lines and MC are in place. Next is bleeding the brakes. And I can say with certainty that routing the lines along/around the front crossmember is NOT much easier. winking smiley The upside is that I can now R&R the front crossmember blindfolded. thumbs up

Starting from the rear and moving towards the front is the way to go. By the time I got to the front of the car I could make measurements and bends with confidence. Said confidence was sorely tested by the front crossmember. drinking smiley

In reply to # 2295288 by PaulP Clay - Classic Tube is the name of the place that sells a pre-bent kit of lines. I need to replace the brake line that goes accross the rear axle. I was hoping they'd sell just the one line, but was told they only sell these as a kit.

http://www.classictube.com/

@Paul: Whoa! $350 bucks?!! That's pretty steep -- I think Gordon is offering a complete brake line kit for MGB right now for $99.95 (they're coiled up of course, so you need to bend 'em but they do have all the nut fittings on the ends). Pretty sure he has (as others do) just the 2 pieces for the rear axle.

Installing these lines is a test of patience and character for sure. winking smiley I used 'cunifer' or copper nickle brake line material to replace my rusting steel original ones. This material is much easier to bend and bieng softer quite easy to adjust at the final fitment. If you go this route, I suggest taping the flares to protect them while fitting the line, they get easily damaged while manhandling to fit.

Maybe it's a stupid question (it won't be my first) but doesn't Moss and/or VB sell pre-bent brake lines that are a direct replacement for those on our B's? I have to replace the line from the MC to the front/right wheel as there is a 'kink' in the line near the connection to the rubber brake line. I was just going to buy a replacement from Moss. Am I missing something? confused smiley

Andy - The only source I've found for pre-formed lines is Classic Tubes. Unfortunately, they only sell the full kit. The Moss lines are cut to length with flares already made, but you'll need to form them yourself. VBs are likely the same.

Any pre-flared kit I've seen is as Paul describes. With the lengths of brake line involved, there'd be no way to properly package them for shipping if they were already bent. The longest one is from the coupler under the passenger side to the rear flex line. The front lines have too many bends in them to package.

I usually make my own lines including flares but that's just me. I modify the layout of the lines so can't go with the stock kit.

UPDATE 2:

Brakes are bled (don't get me started on THAT travail!!) Used MightyVac. It was ok, but next time will pressure bleed.
Now tracking down those little seeps at all the connections... PITA. If I did it over, I'd buy bulk line, fittings, and flaring tool. I'm not convinced that the "one flare fits all" is my best option. Those dang seeping joints...!

Bled the clutch... ughhhh! Done, but spent more time on that ONE bleeding activity than all the brake line combined.

When I replaced the brake lines on an MG the originals literally came apart in pieces so I didn't have old ones to use as templates. What I did was get a roll of very heavy solder. It's easy to bend and will hold it's shape. I made templates out of lengths of solder. Then used those as a template to bend the brake lines - I was able to get pretty good basic shapes for each line. It was then fairly easy to fine tune the fit of each individual line on the car. It actually came out pretty nice. Although definitely not the kind of thing to try to do in a hurry.

Just finished replacing all the brake lines with the stainless tube from Classic Tube, but not pre-bent. It came in a coil and was not hard to form. Made sample lines from heavy copper wire, and used photos of the original lines for routing.
You would have to work hard to kink this stuff, it is great to work with. Also they sell the proper "British" male and female nuts in stainless.
This is a MGC with a lot more lines than a "B" and it only took a couple days work. The good part is that with using stainless lines or copper/nickel, with the same amount of work you get lines that will outlast the owner.

Rich:

Have a look about 2/3 of the way down for brake line install pics.
