On my 47 3600 with the OEM master cylinder under the floor and SM420 transmission that came in the truck when I bought it. Both arms on the firewall parallel to the floorboard. New rubber bumpers on the arms. The brake pedal is about 2 inches higher that the clutch pedal. It seems high to me. I was thinking about shortening the pedal to be more level with the clutch pedal. I have more than 8” of pedal above the floor. The clutch pedal is 8.5” long the brake pedal is 11” long. The distance on the connecting arms to the floorboard is not equal between them so they can’t be the same length I get that. But the pedals can be closer to height if I choose to alter the brake pedal. I am building this truck to be better driving that it was when I bought it. I have hard brake pedal at 3” of pedal travel. What would be your guys opinion. Does anyone have pictures of their clutch and brake pedals?
