*The project in this tutorial used a Corvette 1-inch master cylinder, and a 7-inch single stage booster. This combination turned out to be "close enough". The brakes are a vast improvement over manual drums, but not perfect. Stopping power is great, until about the last 20% of pedal travel, as several test panic stops revealed. At the very bottom, you just can’t push hard enough to lock them up. The system probably needs a 9 or 10 inch booster to be perfect. There simply isn't enough power in a 7-inch booster to lock up a set of 215x75 15s on a 3500 pound car, on dry pavement. | *The project in this tutorial used a Corvette 1-inch master cylinder, and a 7-inch single stage booster.

| + | 2 years later - Never really happy with the 7 inch booster. Moved some things under the hood to get more room and installed a 9 inch dual diaphram booster from a mid 90's camaro. Now it stops like a new car. I'll never use a 7 inch booster again. | ||
