Adjustment Arm 25 Teeth 3501205AA2Q/A*000 for Faw Heavy Duty Truck Left and Right

This rear adjustment arm (also known as automatic brake adjuster or slack adjuster) with 25 teeth spline and part numbers 3501205AA2Q (Left) and A*000 (Right) is specially designed for Faw heavy duty trucks. This critical component automatically maintains proper brake clearance between the brake lining and drum, ensuring consistent braking performance without manual adjustment.

Made of high-strength alloy steel with precision gear cutting and heat treatment, each adjustment arm features excellent wear resistance, reliable automatic adjustment mechanism, and long service life. The 25-tooth spline ensures precise engagement with the brake camshaft. The one-way clutch design compensates for brake lining wear while preventing over-adjustment. The robust construction is specifically engineered to withstand the high torque and repeated cycling encountered in heavy duty air brake systems, delivering consistent braking performance under full load and long-haul operation conditions.
