Description

Overview

The Manual Slack Adjuster 28 Spline 38mm is a practical replacement for S-cam drum brake setups where the spline size and arm geometry must match exactly. It helps restore predictable brake stroke adjustment without changing the rest of the foundation brake hardware. Because slack adjusters sit at the centre of mechanical brake setting, correct selection can reduce uneven lining wear and improve day to day braking feel.

Features

The Manual Slack Adjuster 28 Spline 38mm supports straightforward adjustment with common hand tools, so it suits maintenance schedules that rely on routine checks. The two-hole arm layout also gives you flexibility when matching existing linkage geometry.

• Manual adjustment design for simple brake stroke setting
• 28 spline interface for compatible S-cam shafts
• Two arm holes to suit common linkage positions
• General purpose fitment style for many heavy vehicle applications

Specifications and Materials

Match the spline and arm dimensions to the existing unit first, then verify the clevis pin size at the linkage.

• Spline count: 28
• Spline size: 38mm
• Arm holes: 2
• Clevis pin diameter: 12.7mm

Part number: FB5026.

For adjustment and inspection procedures, use the SAF-HOLLAND slack adjuster service manual for reference

Compatibility and Fitment

Confirm your camshaft spline is 28 tooth and suits a 38mm slack adjuster bore, otherwise this part will not seat correctly. Also check the arm hole count and arm position requirements so the clevis and pushrod align without binding. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown, but some changes in installation may be required.

Compliance and Safety

Brake adjustment affects stopping performance, so follow the axle or brake manufacturer procedure and confirm stroke limits during inspection. Recheck fasteners, clevis security, and free movement after any adjustment. Replace worn clevis pins and bushes so the linkage stays consistent over time.

Trailer Applications

The Manual Slack Adjuster 28 Spline 38mm commonly appears on S-cam drum brake systems where manual adjustment remains in service. Selection depends on the camshaft spline and linkage geometry rather than the vehicle badge.

• Heavy trailers using S-cam drum brakes with matching spline size
• General purpose applications where a two-hole arm is required
• Maintenance replacements when the existing adjuster matches these core specs

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

Finally, if any cross-reference number conflicts with your measured spline or linkage layout, rely on the physical match first.
