The precision mechanism at the heart of the brake caliper.
Aymech focuses on the main adjuster mechanisms that run heavy-duty air disc brake calipers. Fewer product lines. Deeper expertise.
Brand and model names are used solely for product identification and compatibility reference.
We don't manufacture everything. We manufacture what's critical.
Heavy-duty brake calipers are made up of hundreds of components. Rather than covers, plastics, and complementary side parts, Aymech specializes in the main mechanism group that compensates for pad wear and drives caliper movement.

Critical motion control for heavy-duty disc brakes.
The mechanisms we produce sit at the center of the system — compensating for pad wear, maintaining running clearance, and helping the caliper operate reliably.
Function-driven
Our product development focus is making sure the mechanism transmits motion accurately and repeatably.
Precision manufacturing
Critical diameters, thread geometries, concentricity and surface finish are machined under controlled processes.
Platform expertise
A manufacturing approach tailored to the operating logic and dimensional requirements of each caliper platform.
A focused product family for the market's leading brake platforms.
Instead of a crowd of side parts, we manufacture the main adjuster mechanisms that actually run the system.
KNORR TYPEComplete Adjuster Mechanism
Complete mechanism with original head, managing caliper movement and pad-clearance compensation.
