Replace according to wear
Brake pads, discs, tyres and wipers do not share a fixed replacement mileage.
Brake pads and discs
Check pad thickness and disc condition. Replace when they reach the wear limit.
Wiper blades
Replace blades that leave streaks, skip across the glass or have damaged rubber.
Tyres
Check tread, damage and cracking, and correct the pressures.
Service checklist
Service A and Service B alternate, normally once a year. Follow the time or kilometres remaining on your dashboard, whichever comes first. Extra work can fall due with either service.
