<< Subject: E30 M3 brake line replacement
 
 I'm planning on replacing the brake lines on an '88 E30 M3 this weekend.
 Anything peculiar about this process like having to have a heavy duty pump
 available?  (Friend of mine with a 944 had a bitch of a time because of
 crazed brake line routing.)

You probably mean the brake hoses, right? If so it's easy, have metric and
standard line wrenches handy, as some made-ups are standard wrench sized.  Use
good rustpenetrant on each union, so as not to twist the DIN bubble flare
steel pipe.  In front, after the flare nuts are loose, pull the pipe (were
talking the steel) out of the old rubber brake line,  remove the clip which
prevents wear through (remembering to reinstall this very important piece).
Now unscrew the old hose after cracking it off the caliper.  Screw new hose
into caliper, using no sealer of any kind, tighten to spec.
Install clip, stretch steel brake pipe into position through the clip.  Using
your fingers,  
thread the flare nut into the new brake hose.  viola.  Rears are about the
same except you will be working under the car.  Short of pressure bleeder with
master cylinder adapter or vacuum pump,  an assistant pumping the pedal  works
good for bleeding.  Observe proper handling procedure of brake fluid.  The dot
4
stuff is harmful to the paint ( removes it) includes finger prints and is
poisonious.  Taking a bath in it for a few hours could make you feel like doo-
doo!  Gloves please.
Also observe ABS bleeding and de-pressurizing procdedures.  Usual disclaimers
apply.
