More than 600 automatic and manual slack adjusters for popular trucks, with a reinforced cover plate and excess-grease valve.
About the line
Definition
Slack adjusters: The lever that turns the push of the brake chamber into rotation of the brake camshaft. It also takes up the lining-to-drum clearance as linings wear; an automatic slack adjuster does this by itself.
Made by plants with more than 30 years in brake parts, on automated casting, cold rolling and induction hardening lines and German and Japanese CNC machines. ERP tracks every adjuster.
Made at partner plants to MARSHALL drawings. Warranty: 5 years on almost all MARSHALL parts.
What goes into it
- 01
Self-adjusting mechanism
S-ABA sets the clearance itself and keeps the right angle, protecting linings, drum and chamber.
- 02
Reinforced cover plate
Cover plates cause about 36% of failures; the MARSHALL plate is stiffer, keeping dirt out.
- 03
Valve for excess grease
About 80–85 g of grease; a valve lets excess out before it damages seals.
