Engineering Appraisal
Hoppers Stoppers regular upgrades are reviewed by a registration authority VASS
approved engineer. This ensures that the product is safe for installation on your
vehicle. You should contact us for advice on compatible master cylinder/booster and
rear brakes and where required; due to power train changes, have the finished
combination inspected by an approved VASS engineer.
As many types of friction materials, wheels, tyres and weights are possible, all final
combinations should be carefully tested to ensure good brake balance.
See the "do's and dont's" section for details on fine-tuning brakes.
