Due to cost concerns, I need to stay with the drum brakes front & rear for now.
Can anyone tell me what the bore size on the wheel cylinders is front & rear ?
Also, should the front cylinders be smaller bore for more line pressuer & better brake balance ?
Unrelated question - how do I change my password on this site ?
1949 chev 3100 3 window. 350hp/327/m21 4 spd, 12 bolt rear, power brakes, 3" dropped axle from Sid's. Disc brakes next.
