Hi Martyn,

Found this: "You check the brake servo (vacuum servo) by pushing the brake pedal repeatedly and then starting the engine with the brake pedal pushed down. If the brake servo works as it should, the brake pedal should move downward slightly as you start the engine."

from here:,as%20you%20start%20the%20engine.

From my experience this slight downward movement sounds about right.

I also found a similar paragraph here:

The last link also has some further info that might help, although some procedures described involve specialist test equipment.

Obviously check for fluid leaks a such. I'm not sure but I think an improperly adjusted handbrake has an effect as well.

Do you need extra effort to stop?

Do they release ok? Or do they almost lock on?

In either case, maybe the servo needs a service.
