Greetings, was wondering about upgradeing my brakes using a brake booster out of an 85 GMC S-15 blazer, is it big enough?? I think the brakes on a modern veh. like this would be better than anything made in 1950. Proportioning wise I was going to go without since they are drum front and rear. I would also use the residual pressure gadgets to help with reaction time and prevent backflow. My local welding shop is going to make the frame mounting bracket.
