Re: 156 Brake Problem Any Help ?
Sounds like there is a leak or blockage in the vacuum side of the servo. I had this many years ago on my rally mini. The vacuum pipe to the servo had perished and would collapse under the external pressure when on over-run and wanting to brake. The first stab at the peddle was OK but if I lifted my foot and planted it again, there was no vacuum left in the servo, so it did not push for me. New hose cured the problem.
So for you, might depend on how the manifild suck gets to the servo.
