A worrying 40% of aftermarket brake discs contain serious defects according to Italian brake manufacturer, Brembo.

In a press conference held in London, Brembo announced its findings following rigorous tests on 5,000 discs purchased at random from across Europe. The conference is part of a European-wide communications initiative to denounce the ‘non-quality phenomenon’.

Andrea Taschini, aftermarket business unit director, Brembo, Italy, says: “Many of the discs tested were big names, all are viewed as direct competitors to Brembo; there were no white box items.

It is vital we bring the issues of quality and potential danger to the attention of the industry. European legislation was passed on pads within six months and yet there is still no law regarding disc quality.”

Cracks, air bubbles, sand particles and incorrectly drilled mounting holes are among the potential problems UK fitters must be aware of, says Taschini.

“Many technicians fail to check the contents of their boxes as they are using a brand name and so trust the product to be well made. However, they need to know that they are the ones who will be held responsible if there is a safety failure.”

Brembo cites poor quality operations within low cost countries as being at the heart of the problem. It wants both the trade and consumers to realize that cheap discs of untraceable origins are a false economy.

Brembo is embarking upon a mail out to garages highlighting its findings .
