Just had my first service at 2,250 miles (yes I am doing a fraction of the mileage that I did before I retired), and the service report states '10% Front pad wear' and the Front discs on '22.78mm - (SMT 21)'. Firstly does anyone know what the 'SMT' stands for?
Secondly it seems remarkably precise measurement on the vehicle to measure to 0.01mm (0.4 thou), as a micrometer would be very inconvenient to use under the wheelarch/vehicle. Assuming it's correct does anyone know what the starting dimension is?
The whole exercise of non-asbestos braking sytstems is a well known area of high wear, so 20,000 or so miles is not unusual in these days for any vehicle to require the dread disc change. The discs appear to be subject to high corrosion rates (pitting and rusting) and these combined effects, together with the modern materials of the pads, give miniscule disc lives compared to the sort of mileage us older drivers were brought up with.
