Shacman Axle Automatic Brake Slack Adjuster DZ90149346041 HD90149346110

The DZ90149346041 / HD90149346110 Automatic Brake Slack Adjuster is a vital mechanical link within S-cam air brake systems. Positioned between the brake chamber pushrod and the brake camshaft, this Shacman brake adjustment arm converts pneumatic chamber thrust into rotational torque to actuate the brake shoes.

Manufactured in ISO9001-certified facilities using high-tensile forged steel, this truck clearance adjustment arm features a precision internal ratcheting mechanism that automatically compensates for brake lining wear during daily operation. Replacing worn or seized manual adjusters with a high-quality DZ90149346041 slack adjuster eliminates the need for frequent manual brake adjustments, prevents uneven lining wear, and maintains maximum braking efficiency.
