Description

Overview

The SAF Caliper Bolt Kit M18 supplies four mounting fasteners for one brake caliper on the SAF ZI9-19W Intradisc INTEGRAL axle. The kit contains three collared mounting bolts and one centring bolt, providing the complete four-bolt arrangement used to secure a single caliper.

All four bolts have M18 x 1.5 threads and 55mm nominal lengths. However, the centring bolt performs a different locating function from the three standard fixing bolts, making the correct combination important during caliper replacement.

• Includes three collared fixing bolts and one centring bolt.
• M18 x 1.5 metric fine threads with 55mm nominal bolt lengths.
• Suitable for the SAF ZI9-19W Intradisc INTEGRAL caliper mounting arrangement.

Compatibility and Fitment

This kit suits the four-bolt caliper mounting arrangement on SAF ZI9-19W Intradisc INTEGRAL axles equipped with the applicable WABCO disc brake calipers.

The three collared bolts secure the caliper in its standard mounting positions, while the separate centring bolt provides the specified locating connection. These fasteners must be fitted in their correct positions.

Before ordering, check the axle identification plate, caliper type and existing mounting hardware. Other SAF axle generations use different bolt diameters and mounting arrangements.

The following cross-reference number identifies the corresponding manufacturer caliper bolt kit for this application. Confirm the axle and caliper configuration before fitting.

Related Parts

The following individual fasteners are used within the same four-bolt mounting arrangement and may be required separately when servicing the caliper.

Compliance and Safety

Caliper mounting bolts are safety-critical fasteners. Before installation, inspect the caliper support, mounting threads and bolt seating surfaces for damage or contamination.

Follow the applicable SAF-Holland workshop instructions for fastener replacement, tightening sequence and torque specifications. Do not substitute ordinary M18 bolts or interchange the collared and centring bolt positions.

After installation, inspect the completed caliper assembly and confirm correct brake operation before returning the trailer to service.

Trailer Applications

The kit is used during caliper replacement and disc brake servicing on SAF ZI9-19W Intradisc INTEGRAL axles fitted to heavy commercial trailers, including semi-trailers and freight transport equipment.

One kit services one caliper. A trailer axle with two calipers requires two kits for a complete mounting bolt replacement.

Why Choose ICS Trailers

The SAF ZI9-19W caliper uses three standard collared bolts and one separate centring bolt. Although all four share the same M18 thread specification, their different mounting functions mean an ordinary set of four identical bolts is unsuitable.

ICS Trailers can assist with identifying the correct caliper mounting hardware for your axle and brake assembly.

• Replace the complete four-bolt mounting set for one caliper using the correct combination of fasteners.
• Send through the axle identification plate, caliper markings or existing bolt measurements if you need assistance selecting the appropriate kit.
