What the AI looks for in Heavy Duty Vehicle Trailer Parts & Kits

Brake shoe kit fitment: Match the drum size (16.5 x 7 is the most common trailer size), the brake type and the FMSI shoe number. Reline both wheels of an axle together. The wrong shoe width or cam style will not seat, and relining one side only causes uneven braking.
Wheel-end kit and spindle type: Identify the axle spindle family (for example TN, TP or TR). Buy the bearing set, seal and hub-cap gasket for that spindle. Seals and bearings that are close but not exact leak oil or fail early.
Slack adjuster replacement: Match the spline count, spline diameter and arm length. Use an automatic slack adjuster, and set it up with the manufacturer's installation template. Wrong geometry causes out-of-adjustment pushrod stroke, a common out-of-service violation.
Brake chamber replacement: Match the chamber type (for example type 30/30 spring brake) and the stroke class (standard or long-stroke) to the opposite side of the axle. Mismatched chambers apply different force on each wheel.
Suspension rebuild kits: Order bushing, pivot and air-spring kits by the suspension maker and model, not by appearance. Similar-looking bushings differ in bore, length and durometer, which affects axle alignment.

Buy shoes with the spring and pin hardware kit. Worn springs and anchor pins are a common reason relined brakes drag or wear unevenly.
