1972 TR6, stock brakes: I recently flushed my brake system and replenished it with Castrol Dot 4 fluid. Each corner was properly bled with great results and good pedal pressure. After installing each wheel and putting the car back on the ground, I started the engine and warmed the car up. With the engine running at normal idle rpm, my brake pressure seemed to drop considerably. After shutting the engine down, my brake pressure returned to normal pressure. So, I am now thinking something is wrong with the booster. All vacuum lines are new with no obvious leaks. I believe this drop in pressure is due to a faulty booster but it doesn't make any sense to me. One would think that the loss of the booster would make the pedal more difficult to depress and not the opposite.
Does anyone have any experience with this happening? I am not sure what my next move will be with this brake system. Could this be vacuum related???? Maybe I need to plug the vacuum line and see if there is any change without the booster..
