GROSS AXLE WEIGHT RATING
A vehicle’s Gross Axle Weight Rating (GAWR) is the specific weight determined to be the maximum allowable weight that can be placed on a vehicle’s axle. The GAWR includes the weight of the truck and/or trailer, passengers and cargo. Drive, Steer and trailer axles all have individual GAWR’s. You can think of GAWR as a weight limit for each of the axles for your truck and trailer.
Overloaded or unevenly distributed heavy loads can make it difficult to control the truck and put stress on the brake system, causing the brakes to be less effective. It’s important to note that all TRP® brake linings exceed the maximum GAWR limit in Australia. However, choosing a 23,000 lb rated lining doesn’t mean it is right for your application. Nor does it mean that you’ll get any service life improvements from the lining. What is important is the application that the lining will be utilized in.

DID YOU KNOW?
Brake drums also play an important role in dissipating heat that is generated through braking. Overheating of the linings can cause glazing, blisters and discolouration, leading to premature wear and reduced performance. TRP® drums are all tested to FMVSS 121 standard and have excellent heat dissipation properties.
