Reply to "Bad brakes"

Anders,
My induction system is just about identical to yours.
This is what I finished fabricating & installed over the weekend.
Both the engine & an electric vacuum pump, (Hella) sucking on a vacuum bottle.
Both lines have check valves just before they enter the bottle.
Then the bottle is connected to the brake booster with the boosters standard check valve.
On the end of the bottle I have a Vacuum switch which is adjustable.
I adjusted it so the electric vacuum pump will suck up to 20hg, then switch off, when the vacuum drops to 15hg the pump switches back on again.
Tested over the weekend & the brakes are very progressive.
When you push the pedal right down the car nearly stands on its nose.
Made a huge difference to the braking performance.

Regards,
Tony.
