Heavy Duty Automatic Brake Slack Adjusters Manufacturer
As Turkey's leading commercial vehicle brake manufacturer, we produce high-precision automatic slack adjusters with 10T, 26T, and 28T splines, multiple arm lengths (127mm to 250mm), and heavy-duty control arms certified to IATF 16949.
Heavy Duty Automatic Slack Adjuster Engineering
GOS Brake Systems automatic brake adjusters maintain uniform drum-to-lining clearance automatically, eliminating manual adjustment and guaranteeing balanced braking force across all axles.
10T, 26T & 28T Precision Broaching
Camshaft splines broached to strict micron tolerances ensuring zero backlash and positive torque transfer even under extreme braking cycles.
Continuous Clearance Adjustment
High-precision internal clutch and one-way ratchet mechanism adjusts clearance on brake release stroke, preventing drum drag and brake lining glazing.
Forged Alloy Housing (GGG50/42CrMo4)
Ultra-rugged ductile iron and forged alloy body withstands over 3,000 Nm torsional shock loads, gravel impact, road salt and sub-zero temperatures.
IATF 16949 Certified Dynamometer Test
100% bench endurance tested with 500,000 continuous stroke cycles simulating over 1,000,000 km of heavy freight service.

Automatic Slack Adjuster Engineering FAQs
What is the primary function of an automatic slack adjuster in air brake systems?
Automatic slack adjusters continuously regulate the clearance between brake shoes and the brake drum as friction linings wear down. This ensures that the brake chamber pushrod travel stays within safe DOT/ECE R13 limits, preventing delayed braking response or brake failure under heavy transport loads.
How do I identify the correct spline count and arm length for replacement?
First, count the splines on your S-camshaft (most European trucks use 10-teeth, 26-teeth, or 28-teeth with 1.5" or 1.25" shaft diameter). Second, measure the center-to-center distance from the camshaft hole to the clevis pin hole (typically 127mm, 152mm, 165mm, or 178mm). GOS Brake produces direct drop-in units for all standard configurations.
