Hello all,
I have removed the troublesome MK2A Girling servo and installed a Lockheed.
As soon as I start the car without touching the brake pedal the brakes lock on.
When I take the cap off the white plastic breather ( under the letters "O" on the picture, it just pulls off and has a piece of plastic and a foam filter inside) and pull the little plunger up the brakes come off and I can roll the car.
If I disconnect the vacuum to the servo the brakes do not lock on.
HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
