Here is what I have happening:
1. I have to refill the brake fluid about 1 time per month. No brake
leaks on any wheels or master cylinder visible.
2. when I push on the brake, the engine speeds up slightly, when I
let off, it drops back down.
since I rebuilt the back cylinders and bled the fronts, I am making
the assumption that the vacuum booster is leaking when I press on
the brakes. Anyone have an opinion?
here is the real question: what happens if I plug off the vacuum
line, how bad will the brakes get? Does anyone have any idea what I
am likely to find if I dismantle the booster? if the rubber has a
hole in it, can I use something like you patch bike tires (with the
vulcanizing step) to fix it? Or will it be melted and not be
reassemblable (pardon the new word)?
I also figure its contaminating the engine oil as it is probably
getting sucked out. But with a refill per month, it cannot be real
bad (thats maybe 2 or 3 oz per month that is disappearing).
If I block the vacuum line off, will the master cylinder still have
a leak or will it stop since it will no longer be subjected to a
vacuum?

bad brake booster in 71 sedan?
Re: bad brake booster in 71 sedan?
I HAVE SEEN SOME CARS THAT BYPASSED (BRAKE LINES)THE BOOSTER ALTOGETHER.
BRAKES STILL WORK FINE.
SOMEONE TOLD ME THAT HONDA ONLY PUT BOOSTERS IN CARS FOR AMERICA.
IF THATS TRUE THEN IT CAN'T MAKE MUCH DIFFERENCE.
THAT WHAT I AM GOING TO DO TO MINE.

Re: bad brake booster in 71 sedan?
Hi Fred;
There is some truth to that since the power booster was placed on all Sedans starting with chassis number 1013055, which is also the first Sedan to come into Hawaii. But other countries also had power front disc brakes. Which is the issue, the cars that didn't have front disc brakes didn't have boosters either. but I know Honda was testing them as early as chassis number 10001188, which was a test vehicle for Honda. Yes I have the list of countries that didn't have front disc brakes, but I have to look for it.
