GBSC releases safety alert on brake pad failure modes, consequences

As is increasingly the case, there is far more to visible or apparent corrosion than meets the eye. In the case of brakes, red rust on a rotor surface that is visible through your wheel is just the tip of the iceberg. This visible layer of rust may even be easily wiped away by applying the brakes a few times while driving. On the other hand, the effect of that same rust-producing environment on the brake pads (which you cannot see) are advanced corrosion that results in progressive deterioration and the rotting of the pads with rust, leading to separation between the brake pad and the brake system.

It has also been observed that a significantly high number of pads are being replaced before the friction lining has been worn to a replacement level.

These concerning general observations have together provided the basis to launch the systematic brake-field study described below. Results from this study will provide an opportunity to share field-use observations related to brake pad rust and its direct impact on vehicle safety, there by providing awareness to the industry and consumers.
