What to check before viewing

The model's most common MOT issues, turned into things you can ask about or look for.

Brake pads

High priority

Ask when the pads were last replaced and check the warning-light history.

Brake discs

High priority

Ask for the date and mileage of the last disc replacement; visually check for a deep wear lip and rust pitting on each disc.

Tyres

Worth checking

Check tread depth across the full width on all four; uneven wear suggests alignment or suspension issues.

Vehicle-specific check

Worth checking

Check the car’s number plate on MOT Wise to see its own MOT history and any recalls for its build years.
