Practical experience has shown that the braking deceleration performance standard for drum brakes is often not achievable.
Thanks to the disc brakes on trucks and the Electronic Brakeforce Distribution system, drum brakes on trailers are subjected to less stress. As a result, the brake lining becomes glazed and the APK braking deceleration requirements are not met.
The UNDERCARRIAGE committee is currently mapping out which members along with which specifications and applications are experiencing problems with the glazing of drum brake linings. Through the help of a technical solution, TRTA wants to see to it that the high costs involved in failing to achieve braking deceleration are prevented.
