The Stovebolt Site Forums The Parking Lot Big Bolts air disc brakes, input wanted

i disagreewith steve's statement the pedal feels the same regardless of adjustment. if your brakes are out of adjustment on more than one axle you know it as soon as you hit the pedal. on a normal stop you will use 20lbs or less pedal pressure in an air brake system. if your brakes are out of tolerence you will use more pressure to make even a moderate stop. if some idiot cuts you off there's never enough airpressure regardless of how well adjusted your brakes are. if you are considering replacing standard slack adjusters with automatic slack adjusters you still have to check them fairly often as they don't always work. agree with c10 bill maxi brakes good idea. older trailers the brakes would come on with loss of air pressure but when air pressure was completly gone they would release again so you could pull the trailer again with no brakes. not sure how that worked with the tractors as all those i got where equipped with maxi brakes. which brings us back to griggs original post. if the air disc he is looking at are single action how do they apply the parking brake?
