MC heat causing brakes to apply...progress report.

[Doyt W. Echelberger]

I replaced the MC on my 87 5ktq on 6/27 with a new (not-rebuilt) unit.
Normal summer heat in the engine bay during stop-and-go traffic had
resulted in a gradual buildup of pressure in the brake lines, and severe
binding of all 4 brakes, relieved only by cooling the original MC.

Under similar conditions 6/28, the system containing the new MC did not
display those problems.

Car rolled easily from stop, with dash gauge reading a bit past half
way....same reading as when they were binding with the old MC.
