"Transitional" setup

To avoid a mix and match brake system why not wait until you do the conversion to switch masters? Takes the guess work and the possible danger out of the formula for now . You are defineately in a grey area here as I did the scarebird conversion and Im still using the drum porportioning valve with no probs ...stops great and the pedal feel is good too . stops well even from 100+. I eventually changed over to a power disc brake master (without power booster ) and can't tell any difference ......very grey area indeed
