Can't seem to get much stopping power, soft brake pedal. Our setup is as follows: Disc front , drums rear, booster and master cylinder under floor. Prop valve, 2 lb. residual valve to front, 10 lb. residual valve to rear. Have bleed brakes and master cylinder 3 times, no air in line. A mechanic friend said to try separate lines to the front disc's, presently have one line with a T fitting to send fluid to both front brakes. He also said maybe an adjustable prop valve to the rears. Anybody have this type of brake pllumbing? Or any suggestions on what we can do. Thanks Frank
