VS Commodore Brake Issues
Phoenix Mechanical
Soaring

Disc rotors - All disc rotors have a minimum recommended thickness. As the brake rotor wears it becomes thinner and the recommended minimum thickness indicates when the brake rotor should be thrown away. This thickness is crucial for optimum braking, and many disc rotors are marked with their recommended thickness. Genuine rotors are useable down to 21mm, where as some aftermarket rotors can be used down to 20mm. If the rotor is used beyond this point, braking efficiency is greatly reduced. In many cases undersized disks result in excessive pedal travel, brake fade, pulsing brake pedal from rotor warping and generally ineffective brakes.

Hand brake - Commodores use the internal area of the disc as a brake drum for the park brake. Incorrect or inadequate adjustment of the handbrake shoes and cable will result in poor handbrake operation.

Front Hubs - VS Commodores have front bearing hubs independant of the disc rotor. (Eg; the disc can be removed while the hub (including bearings and studs) remains attached to the strut.) Ideally these are more durable and can handle more load. Unfortunately when these bearings wear, either through age or knocking the occasional gutter, the bearings can not be replaced on their own and a complete hub will be required. Worn hub bearings will produce a bearing groan which varies with speed and cornering. Not all VS hubs are the same though. The hubs vary from standard, to ABS, and to ABS with IRS.
