Re: IML: 66 Drum brake issue

[PAUL WENTINK <randalpark@xxxxxxx>]

Aren't proportioning valves used on cars with disc brakes in the front, 
and drums in the rear? I don't think a '66 Imperial had one, unless we 
are talking about a converted brake system here. Then all bets are off.

  Proportioning valve problem(maybe some crud got stuck in there)? 
 
  There's probably a rubber line in the back - if it's gotten weak, it 
might be 'inflated' by line pressure, so it's keeping the rear brakes 
partially actuated all the time, and they grab first. This happened on 
my '67 Polara.
