High temperatures affecting brakes

[markallen at hannaford.com]

On my '88 5kcstq the warmer the weather the greater the chance the brake
dragged - in this case my front right caliper. On a trip through Boston on
a hot summer day(June '01) with heavy traffic I ended up with a smoking
wheel. My understanding this is a classic sign of a failing master brake
cylinder. In my case I replaced the car (with a V8) before fixing the m.c..
