I have 1954 3600 pu with disc brake conversion and rear drums. I have either a 7" or 8" power booster from CPP with their dual master cylinder. I have had the unit on for two years and have never been happy with the stopping power. I have a good pedal with rear shoes adjusted up but cant get a tire to squeal. Any suggestions? Have boost available because when you start motor the pedal drops a little. I measured the booster across the whole front edge and it seems to be 8".
Thanks Sharon
