Textar testing shows compatible CV brake parts

decrease the risk of disc cracking

Leverkusen, 20 June 2018 – Premium brake brand, Textar, has warned that the incompatibility of Commercial Vehicle (CV) brake pads and brake discs can cause hairline cracks after only a few hard brake applications, following extensive research. During a benchmark exercise, truck brake discs and pads from various manufacturers were tested to see if parts that did not match were less effective than compatible parts from the same manufacturer. The results showed that if the brake pad and disc did not match, and therefore were not compatible to the best possible extent, the first hairline cracks in the brake disc could start to form after just a few hard brake applications. These hairline cracks become deeper with each subsequent braking application. Incompatible pads and discs were shown to not only influence the safety of the vehicle but also increase wear on the brake pads.

As trucks and heavy-duty commercial vehicles rely considerably on safety measures and a long service life, original equipment manufacturers (OEMs) have given great importance to precisely matching brake pads and discs for some time. This idea is yet to become established in the spare parts market, which is something Textar is hoping to change with the results of its most recent tests.

Thomas Ahlfeld, Product Manager CV at TMD Friction, the manufacturer behind the Textar brand, said: “Cracks in the brake disc act like a plane on the brake pad. The cracks remove the friction material from the brake pad and will need to be replaced earlier than otherwise required as a result”.

To avoid the premature and expensive replacement of brake pads and discs in trucks, especially on the rear axle, Textar recommends always ensuring a perfectly matched combination of brake pads and brake discs are fitted, as well as regularly checking the brake discs for cracks. If these steps are taken, vehicle downtime can be prevented.
