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. The data below is preliminary technical information for matching product configurations.
Main mechanism solutions for major caliper platforms.
Rather than a broad but shallow catalog, we focus on the critical adjuster mechanism families that actually matter in the market.

Brand and model names are used solely for product identification and compatibility reference.
KNORR TYPEComplete Adjuster Mechanism
Complete mechanism with original head, managing caliper movement and pad-clearance compensation.
KNORR TYPEHex-Head Adjuster Mechanism
Complete mechanism with a hex wrench socket at the front end, allowing manual service intervention with a standard socket.
KNORR TYPEEarless, Springless Fixed Adjuster
Fixed adjuster shaft with no ear or spring, featuring a four-lobed rear head with a gear-shield assembly.
KNORR TYPEMilled, Springless Fixed Adjuster
Fixed adjuster shaft for the relevant KNORR caliper platforms, featuring an internally milled center connection and a springless body.
KNORR TYPEEared, Springless Fixed Adjuster
A springless fixed adjuster mechanism variant, distinguished by the positioning ear on its front shield.
KNORR TYPEPlastic-Bushed, Spring-Loaded Fixed Adjuster
A version that combines a plastic bushing and coil-spring body construction in the same fixed adjuster shaft.
KNORR TYPESpring-Body Fixed Adjuster
A variant specific to the SL7 family, featuring a long black body, an exposed spring at the rear, and an eared front shield.
WABCO TYPEPAN 17 Adjuster Mechanism
A 17.5-inch class adjuster mechanism with a shorter body, specific to the PAN 17 platform with a 109 mm mounting length.
WABCO TYPEPAN 19 Adjuster Mechanism
A mechanism specific to the PAN 19 / PAN 19-1 platform with a 115 mm mounting length — 6 mm longer than the PAN 17, with different internal dimensions.
WABCO TYPEComplete Mechanism Set
The bidirectional adjuster mechanism set for the platform, designed for axle loads of up to 10 tonnes and brake torque of up to 21,000 Nm.
MERITOR TYPEGeared and Capped Adjuster Mechanism
Combines a central gear, dual guide bearings and a cap assembly into a single functional mechanism.
The mechanism that drives the brake caliper's movement is at the center of our production.
Aymech has focused for years on the established adjuster mechanisms used in heavy-duty brake systems. Every product is handled in a way that preserves the same operating logic, dimensional fit and series-production continuity.
Precision machining
Critical surfaces, threads and connection geometries are machined to controlled tolerances.
Function testing
Motion, running clearance and mechanism fit are checked before shipment.
Product continuity
A repeatable quality and reliable-supply approach for established brake platforms.
Length and weight values are approximate technical references for matching product configurations. The weight of PAN 17 and PAN 19 mechanisms is approximately 2 kg depending on configuration. WABCO, KNORR and MERITOR names are used solely as compatibility references. Unless otherwise stated, the codes shown are aftermarket cross-references.
