I had to go look … the Jetta does have a lever on the side - presumably for adjusting the bias between front and rear.

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.
