How master cylinders fail, the difference between OE and remanufactured, and what to inspect alongside the cylinder itself.

How calipers work, the common UK failure modes (especially seized rear calipers), and the brand differences in remanufactured units.

A guide to the wheel-speed sensors that drive ABS, ESP and traction-control systems — what fails and how to diagnose.

Master cylinder, brake pipes, hoses, calipers, ABS modulator — how the hydraulic system is laid out and what fails first.

The small electrical sensor that warns of worn brake pads — and why fitting new pads without new sensors is a false economy.
