BSC Tools' NEW rotor truing fork features two rotor truing slots of different lengths, one short (14 mm) for small buckles and a deeper one (44 mm) for more significant bends. The tool also features minimum thickness gauges for most popular rotors on the market - all you need to do is attempt to slide the rotor into the corresponding slot for it's model and it if fits, it's worn and needs replacing.

Alongside a chain wear tool, this rotor wear tool is an essential tool that our home mechanic tutor Keith will insist you use regularly to maintain braking performance and avoid big service bills.
