Re: [DML] Brake question

[Warren Wallingford <warren@xxxxxxxxxx>]

First of all, there's nothing particularly confusing or mysterious about 
Delorean brakes.  They're vacuum boosted hydraulic disc brakes with 
two-piston calipers in all four corners.  The master cylinder does the 
front-to-rear proportioning.  Any shop that looks confused surely is. 
Leave straightaway.
That said, your problem is most likely the master cylinder.  If the 
pedal is over-hard, the vacuum servo or the vacuum feed to the servo 
could be faulty.  We carry our own newly-made brake master that features 
correct 62/38 proportioning and a cool cast-in DMC logo.  Part number 
105543, $124.95.  Easy installation. Here's a pic:
