     I had brake problems, and I drive too fast to depend on the stock brakes. My first problem was the combination valve mounted on the frame. After 20+ years I could tell a buildup of sludge was in there. I couldn't blow air through it, so I knew brake fluid couldn't freely flow to the front calipers. Replacing it would be costly and I didn't need the built in drum brake proportioning valve. I replaced it with a simple distribution block from a 1967 Mustang, and a separate adjustable proportioning valve.

     My second problem was finding a good rebuilt master cylinder. I didn't trust the rebuilt master cylinders using 20+ year old cores. So I choose a newer style aluminum master cylinder from a 2002 Ford Lightning Truck. It has larger 1-1/4" bore which fill the larger calipers pistons quicker. I am very happy with this decision, the whole system works great! I kept the stock power brake booster because I've never had a problem pushing the brake pedal.

PLEASE DO YOUR OWN RESEARCH, MY IDEAS MAY NOT WORK FOR YOU!
