I’ll give it a go Roy . The “German Bentley “ was the only place i had come across that method until your reply.

But don’t have any hockey sticks to use, don’t tell anyone Roy, I’ll be deported :-)

One thing especially intriguing, that is a special tool that goes between the driver’s seat and the brake pedal. It’s just and adjustable bar and it seems the brake pedal is pushed , not full way down, during pressure bleeding.
