Description

Overview

Booster yoke and pin assembly 1/2in 5/8in connects an air brake chamber pushrod to linkage hardware on heavy trailers. It helps restore correct movement at the clevis point when the existing yoke or pin wears. This assembly suits common brake chamber linkage setups where a 5/8in threaded yoke and 1/2in pin are required.

Features

Booster yoke and pin assembly 1/2in 5/8in simplifies brake linkage repairs by replacing the wear point as a complete set.

• Yoke and pin supplied as an assembly for straightforward service
• 1/2in pin size for linkage connection points
• 5/8in thread size to suit compatible pushrod ends
• Supports smooth, consistent brake actuation when correctly fitted

Specifications and Materials

The key selection points are the pin size and thread size so you can match the existing linkage without guesswork.

• Pin size: 1/2in
• Thread size: 5/8in
• Type: booster yoke and pin assembly for brake chamber linkage
• Supply: assembly includes yoke and pin

Part number: AB1177.

Compatibility and Fitment

Confirm your brake chamber pushrod uses a 5/8in threaded yoke and that the linkage connection point takes a 1/2in pin. If the thread form or pin arrangement differs on your setup, choose the correct yoke and pin size to avoid binding or uneven brake response.

Compliance and Safety

Inspect the clevis, pin, and retaining hardware during service so worn linkage parts do not mask brake adjustment issues. Follow the trailer and brake component manufacturer service instructions for safe installation and checking, then recheck linkage movement after fitment to confirm free travel and consistent braking response.

Trailer Applications

Booster yoke and pin assembly 1/2in 5/8in is used on heavy trailer air brake systems where the brake chamber pushrod links to the rest of the actuation hardware. It suits routine maintenance when a clevis point shows elongation, looseness, or inconsistent motion, so it is a practical service part for fleets, workshops, and owner operators maintaining air brake linkage reliability.
