| − | + | *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 7in booster to lock up a set of 215x75 15s on a 3500 pound car, on dry pavement. | |
