I converted my 72 charger from 4 wheel manual drums to power front disc/rear drums. I changed everything from booster/master cylinder to calipers/wheel cylinders and all lines and hoses. Everything works but the brake pedal does not come up to the same height and the brake light switch is not even close to making contact with pedal. Is there something else I need to change? Or is there a different switch I can use to make up the difference?
