For the power assist disc brake setup there are two main arrangements. The first, used on early HK, has the pushrod connected to the brake pedal on a different axis to the vacuum booster centre axis. To adapt the pedal pushrod to the booster there is a relay lever, and pivot located in the booster bracket. I believe this was changed about mid 1968 to the same arrangement seen on all HT and HG, where the pedal pushrod is aligned with the centreline of the booster. I think you need to have the booster relief "dent" in the right hand inner fender of your subframe if you want to use the direct acting booster arrangement.

Yes, drill the firewall where required, there should be a small dent punched to locate the drilling position.

If at first you don't succeed, just call it Version 1.0 |
