Searched but can't seem to find a thread on this topic. Ok so I've got the blue roadster driving but when I start the engine the brake booster pulls the pedal down. I found that I forgot to tighten the two nuts securing the MC to the booster and fixed that. Problem was better but when I start to press the brake pedal the booster takes over and then pulls the pedal down. The pedal does come back up after about 2-3 seconds but definitely not the way it is supposed to work. Other forums suggest bad booster but it was working fine just before the restoration of the car a year ago. Thoughts?
