Haldex India Limited manufactures Manual or Slack Brake Adjuster Assembly. Manual or Slack Brake Adjuster Assembly is used on commercial vehicles having Air Brakes with `S` cam shaft. This device is used to transmit the braking torque to the `S` cam and to facilitate adjustment of the clearance between brake lining and the brake drum which is caused due to the wearing of brake lining.
Haldex India Limited is the supplier of manual and automatic slack adjusters for air brakes of commercial vehicles. Manual or Slack Brake Adjuster Assembly is mounted on the `S` cam shaft and one end is connected to the push rod of the brake chamber. When the brake pedal is pressed, the air is let into the brake chamber and pushes the push rod out. This in turn moves the slack adjuster assembly. As slack adjuster assembly is mounted on the `S` cam shaft, the shaft rotates and forces the brake shoes away from another and presses against the brake drum & the brake is applied.
