What happens to the air when you push the brake pedal on S-Cam brakes?
What happens to the air when you push the brake pedal on S-Cam brakes?
  • Air pressure is released along the slack adjuster but stops at the wedges.
  • Air pressure is converted into hydraulic pressure.
  • Air pressure forces out the push rod and moves the slack adjuster.
  • Air pressure works only with wedge brakes and not with S-Cam brakes.
