BRAKE SYSTEMS / BRAKE SHOES & HARDWARE KITS
ONE SHOE DOES NOT FIT ALL
21,000 GAWR FRICTION MATERIAL The TRP ® 21K GAWR grade friction is stable and provides excellent wear and fade characteristics. It has consistent braking characteristics, low noise and provides great stopping power. It is best suited for on-highway trailer and truck applications. 23,000 GAWR FRICTION MATERIAL The TRP ® 23K GAWR grade friction material performs extremely well in demanding applications. It is formulated to handle high braking duty cycles encountered in city pick-up and delivery and highway applications where steep grades are negotiated. It is recommended in refuse, mixer, off-road, bus and tanker applications. It provides excellent lining life, superb stopping power, and superior resistance to fade.
TRP® Brake Shoe linings are available in either 21,000 lb or 23,000 lb Gross Axle Weight Rating (GAWR). So why are there 2 different types of linings available and which one is best suited for your application? This guide was developed to help you understand why there are different types of lining material and to help you identify which lining is best suited for your application. There are several different factors that need to be taken into consideration when choosing the right brake lining for your truck or trailer. All brake linings are designed to exceed maximum load limits in Australia so axle ratings, whilst important, don’t play a large role in determining the right lining. Consideration however, must be given to load, road type, braking frequency, maintenance practices, and driver habits when determining the right lining type. What is right for one application may not be suited to another. Brake linings certified at 23,000 lb. could be much too aggressive for some applications, causing the brake drums to wear prematurely or result in brakes that “grab”. Likewise, brakes certified at 21,000 lb. may not provide sufficient braking power to stop some heavy vehicles.
BRAKE LINING SELECTION GUIDE
This table has been developed to help you decide which is the right shoe for you and your application. It’s important to note that linings rated 23K GAWR are not necessarily better. It’s all about the application that you are using your vehicle in.
