What to check before viewing

Brake discs
High priorityAsk for the date and mileage of the last disc replacement; visually check for a deep wear lip and rust pitting on each disc.
Brake pads
High priorityAsk when the pads were last replaced and check the warning-light history.
Tyres

Suspension bushes and joints
Worth checkingListen for knocks over speed bumps and ask about recent control-arm or anti-roll-bar work.

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