Description

Overview

BPW disc spring brake chamber applies service and parking brake force on left-hand BPW disc brake axle positions. The 15/24 chamber size, M16 x 1.5 ports and handed configuration make it important to match the removed chamber before ordering.

Features

  • 15/24 disc spring brake chamber for BPW left-hand applications.
  • M16 x 1.5 air ports for matching the existing brake pipe setup.
  • Available in aftermarket and genuine options.
  • Includes fixing nuts for chamber installation.

Specifications and Materials

Part number: AB1146.

This BPW disc spring brake chamber uses a diaphragm-diaphragm 15/24 configuration for disc brake axle service. It matches left-hand chamber positions where the mounting orientation, port thread and chamber size align with the original unit.

The chamber suits M16 x 1.5 port connections and BPW 15/24 disc brake cylinder layouts. Also check the brake hose routing and mounting clearance before fitting, because chamber hand and port position affect installation.

See the BPW brake cylinder technical guide
