‘Weld On’ Axle Brackets

Weld on axle brackets to fit dual supply hydraulic/pneumatic brake actuators and standard air chambers. This involves installing the correct mounting brackets onto a vehicle’s axle to support both dual-supply brake actuators (used in combination braking systems) and standard air brake chambers (used in traditional air braking systems). Here’s a breakdown of what this involves:

A20705U AIR CHAMBER BRACKET (T09/12/16/20/24)
A20705XL AIR CHAMBER BRACKET XL (T30/36)

Purpose of the Weld-On Axle Brackets

These brackets provide mounting points for the brake components, aligning them correctly with the axle and brake hardware (e.g., slack adjusters, S-cams, discs, or drums). They need to withstand high mechanical and thermal loads from braking forces.

 

Brake System Types Involved

  1. Dual Supply Hydraulic/Pneumatic Actuators:
    • Found in trailers or vehicles that can receive air or hydraulic input, depending on the towing vehicle.
    • Common in interchangeable fleet trailers.
    • Require mounting points that accommodate both a pushrod (like an air chamber) and hydraulic line routing.
  2. Standard Air Chambers:
    • Used in traditional air brake systems.
    • Include service and spring brake chambers.
    • Mount with a standard bolt-on pattern to brackets on the axle.
