Wabco Type Air Disc Brake Caliper Caliper Adjusting Mechanism 115mm for SAF Axles PAN 19-1

This 115mm adjusting mechanism fits Wabco-style air disc brake calipers and matches SAF axle PAN 19-1. As a core internal caliper part, it automatically compensates for brake pad wear to maintain optimal working clearance. It’s engineered specifically for trailer and commercial vehicle brake systems, delivering steady braking performance even under long-distance travel and heavy-duty working conditions.
Brake pads naturally wear thin over time from constant friction during daily runs. If no automatic compensation is available, brake travel will become overly long, leading to unstable braking feedback. Built inside the caliper, this adjusting mechanism self-eliminates the wear gap in real time, keeping the whole brake system well calibrated and cutting down unnecessary manual adjustment work.
It is widely compatible with mainstream European trailer axles, particularly SAF axle platforms commonly seen in logistics fleets, container transportation and long-haul freight routes. These working scenarios feature heavy payloads and frequent braking, making dependable brake components critical for operational safety.
The dedicated 115mm dimension is precision engineered for specific caliper structures, guaranteeing seamless installation and reliable running after replacement. For most repair scenarios, it can be replaced individually instead of swapping out the entire caliper assembly, effectively lowering maintenance expenses and shortening vehicle downtime.
Though compact in size, this internal mechanism is vital to sustaining sensitive, consistent braking performance and extending the overall service life of the entire disc brake assembly.
