    e28 brake booster/servo in e21

    Hi All,

    Just changed my brake booster/servo with one from an e28.

    Modification required:

    1. Mounting bracket on servo needs to be shortened. From about 2.5
    inches to about 1.25 inches.
    2. Knocking of the tyre-well to accommodate the larger servo.
    3. Re-use original e21 brake master pump. (e28 master pump has two
    outlets only, vs 3 with the e21 brake master pump)
    4. Shorten the joint with the brake levers (i.e., connection between
    servo and the brake levers (just behind the headlights.

    Braking is now much more progressive. Shorter stopping distance and
    feels less likely to lock up Don't have to press the brake pedal as
    hard as I had to previously.

    Next step, my Volvo 4-pot calipers.

    Has anyone done this before?

    Photos will follow later.
    Power is nothing without control.
