Really love this car and experience of driving it (see post on General Discussion).
Car has the Detroit Gear automatic and power brakes. During recent removal and rebuild of the engine, found that the Hydrovac had been disconnected and bypassed. (Pedal had been firm but not difficult to manage). Now that the Hydrovac has been rebuilt and reinstalled, there are occasional unexpected surges of excess boost as car comes to a stop. More alarming is a recent instance of brakes becoming hot and fading badly during 8 to 10 miles of very moderate driving. I understand that the master cylinder is a potential culprit. The anti-creep switch and valve are still in place... another possible cause? I'll have the wheel brake adjustments checked, although there's been no recent work on the linings. I strongly suspect the rebuilt Hydrovac unit, but how can I confirm this?
