Brakes — 2.7% of failures
Brakes issues account for 2.7% of MOT failures on 1970 MG Mgbgt models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Lamps, Reflectors and Electrical Equipment — 1.4% of failures
Lamps, Reflectors and Electrical Equipment issues account for 1.4% of MOT failures on 1970 MG Mgbgt models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail.

Replace any blown bulbs before the test.
