After consulting with many drivers of Malibu's and Monte Carlo's, I decided to try the power master with the modified brake pedal pushrod position.
Most of these guys that have done the brakes this way, did not do any research, just did it and it works, at least for them.
This is a disk front and drum rear setup.
Will have the car running soon and do some testing and report on the effectiveness of the brakes as well as the pedal effort.
