When to service & replace parts

Replacement intervals

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.
