[Healeys] Rear breaks locking

[Bob Spidell]

  Magnus,

Are you saying the newer materials used in the shoes are causing this problem?  That would mean, I guess, that the new 
shoe linings are more effective than the old (actually, TOO effective).

I've noticed in the past that one or the other rear brake would lock before the fronts (BJ8).  I put new shoes in a 
couple years ago and when I missed a turn and slammed on the brake pedal recently I got pretty even locking all around IIRC.

Presumably, then, someone with all drum brakes wouldn't have the rear-only lockup problem, and a proportioning valve 
would solve this problem?
