Rear Brakes Locking up first

[ccarpen at earthlink.net (Cris Carpenter)]

If this is true on his car, then lowering it would not have made this 
happen, right? The inline type of proportioning valve is not load sensing 
to the best of my knowledge. In which case, the problem can't be adjusted 
away, and would likely be related to the master cylinder and/or 
proportioning valves (assuming there is nothing wrong with the front brakes).

I remember one situation when I was a technician where a diesel rabbit 
owner was complaining of a lack of stopping power. I found and repaired a 
problem with the vacuum pump that supplies vacuum to the brake booster. A 
couple of days later, she came back and said the brake pedal felt better 
but the car still would not stop well. We took it out for a drive together 
and I tried a hard stop from 50 mph. Sure enough, the car did not want to 
stop. But it was not because of the brakes. The road was a bit wet and the 
front tires were bald, so the front brakes were locking up and sliding 
right away. New front tires and the "brake" problem was fixed.
