engine and drivetrain Rear-End Re-Assembly Question

[worzella]

Quick question for anyone who has re-built their rear-end suspension and brakes.

 

The wonderful day has finally come where my 1975's underside is cleaned and painted and I can re-install the subframe, trailing arms, shocks, springs, brakes, etc.... woo hoo.

 

But, I mangled the long rear brake pipe that comes from the engine bay to the L/R distribution brake fitting under the center of car... that brass guy that is bolted to the underside of the pan.

 

My questions is.... can I replace that long pipe AFTER I have the whole subframe, etc re-installed... in other words will I be able to work it up and around everything in order to conenct it to the splitter fitting?

 

If my question is not clear, let me know ... and thanks

You can fix it later but it would be easier to do it before rear is in place

A lot easier to do with engine, tranny, drive shaft AND rear sub frame out.

Do it now before you put anything else in.

BMW replacement brake line is fairly easy to bend but the really tricky section for the main rear line is in the engine compartment from the master cylinder thru the 90° bend down and along the tranny.  Once it is located in the tranny tunnel the rest is very easy.  I used the 2338mm line #34.32.6.755.663 for my replacement. Be careful taking out the old line and you can use it for a reference, or take good measurements and possibly photos. And a brake line bending tool also helps to avoid kinks. Good luck.

And if you thread the line from the front with the engine in disconnect the battery first- ask me how I know!

Excellent point! Always disconnect battery when working near the starter.
