Drum Brakes
If your brakes are un balanced or not bringing you to a stop, it’s time to review your drum brakes. We provide testing, inspections, alignment and repairs.
CoF Services
Certificate of Fitness
A CoF is a regular check for heavy vehicles to ensure they’re safe to drive on New Zealand’s roads. The HTSL crew are qualified to perform this biannual check. We check wheel and tyre condition, glazing, steering and suspension, load anchorage systems and much more.
CoF Pre-checks
If you’re unsure of the state of your vehicle, we can perform a pre-check. Our mechanics will carefully inspect your vehicle and then let you know the verdict. If you need anything repaired, you can do it before sitting the CoF.
