Servo problem - B Body

EMU · Post by **EMU** » Wed Jun 04, 08 1:51 pm

When I start the car, the brake pedal does not move or work the brakes. This indicates a servo problem I believe. The pipe to the engine looks ok, but connot fathom the conection to the servo. Should it just pull out?

After a couple of minutes everything works perfectly. Anyone know what the problem is please?

The vac hose may be collapsing internally,or there could be a crack that closes as it gets warm. The non return valve on the servo may be sticking.The connection into the servo is the non return valve and is pushed into a rubber grommet,it should come out with a twist and pull.

I had that - the Servo had failed, you could hear it exhaling....

Thanks for that, will start with the non-return valve, and hope I do not need a new servo,

Failed to make MMA meet as unwell, but looking forward to next one.
Have tried to pick up a new non-return valve for servo, but no success yet.

Anyone suggest a supplier for this ?
Need to sort this as itching to get axel ratio changed next.
