Description

Overview

90 degree disc spring brake chamber supports service, parking and emergency braking on heavy trailer disc brake axle setups. The 12/16 chamber size and 3/8″ ports make it important to match the existing chamber layout, air fittings and mounting position before ordering.

Features

• 12/16 disc spring brake chamber for trailer disc brake applications.
• 90 degree configuration for matching the removed chamber layout.
• 3/8″ ports for compatible air line connection.
• Spring brake design supports parking and emergency brake function.

Specifications and Materials

Part number: AB1123.

This 90 degree disc spring brake chamber uses a 12/16 spring brake configuration with 3/8″ ports. It suits replacement work where the chamber angle, port size and mounting position need to match the existing trailer disc brake actuator setup.

Before fitting, compare the chamber size, port thread, mounting studs, pushrod travel and surrounding clearance against the removed unit. Also check the air line routing so the fittings sit without strain after installation.

See the brake actuator service manual library

Compatibility and Fitment

Match the 12/16 size, 3/8″ ports and 90 degree configuration before ordering. Also confirm the mounting face, actuator clearance and brake hose path, because disc brake chamber layouts vary across axle and caliper setups.

Compliance and Safety

Do not dismantle the spring brake section. Instead, replace the complete chamber if the sealed unit leaks, binds or shows damage, then confirm correct brake application and release before the trailer returns to service.

Trailer Applications

Workshops fit the 90 degree disc spring brake chamber during trailer disc brake repairs where the original 12/16 chamber has failed, leaked or no longer matches safe operating requirements. During the same job, inspect the air fittings, hoses and mounting hardware.
