Common HGV Trailer Braking Issues

August 25th, 2020 Comments off

aide automotive have been promoting the task of individual wheel brake testing using an infra red thermometer for many years.

In a recent Transport Operator publication an article by IMS Ltd, detailed some guidance on using a thermometer to brake check HGV trailers.

The atricle as per below,:

Here’s some guidance to help identify and resolve trailer braking system-related problems experienced when the vehicle is in service.

“The checks outlined are appropriate for a number of the most common problems such as; overheating brakes, poor braking performance and excessive lining/pad wear.

“Modern tractor/trailer combinations have advanced braking electronics.“Real-life dynamic testing helps to provide a clearer picture of the harmonisation between tractor and trailer.

Brake temperature testing is an easy way of determining just how effectively the tractor and trailer are working together.”

IMS continued: “It is recommended that tractor/trailer synchronisation or harmonisation brake adjustment tests are undertaken on a regular basis to ensure that the combination continues to operate safely and efficiently. “For the results to be
meaningful, the vehicle should be tested under normal, daytoday operating conditions.The tractor/trailer combination should be laden and driven in a conventional manner on the roadfor a period of no less than thirty minutes before commencing
tests. “Temperature measurements should be taken as soon as possible after the vehicle arrives at the workshop. The parking brake should not be applied but very importantly, full safety procedures should be observed to secure the vehicle by hocking
the wheels. “The temperature readings should be taken from the same point on each of the drums/ discs using a correctly calibrated, infrared thermometer. Record the findings for later reference. “Make sure that the configuration of the foundation
brakes fully complies with the brake calculation, referring to manufacturers’ specifications as necessary. The manufacturers’ recommendations can be obtained by locating the axle specifications on the axle serial plate. “It is then time to connect to the EBS unit to access the EBS data parameters and check that these are in line with the brake calculation and foundation brake specifications. “Next, conduct a rolling brake test on a DVSA ATF-approved commercial vehicle brake tester and record the findings. “Once all of the necessary data has been gathered, it’s time to share this with the EBS supplier and axle manufacturer to help identify the cause of the problem and to determine the best course of action to resolve it.”

aide automotive market a HGV Temperature Brake Check gun alone or with a kit of a brake tester (Bowmonk) Truck Or the Truck & Trailer version.
