sch.2-sec.88 What braking system a heavy motor vehicle must have
A heavy motor vehicle with 4 or more wheels built, or used, mainly for transporting goods or passengers by road must be fitted with— a braking system that— consists of brakes fitted to all wheels of the vehicle; and has at least 2 separate methods of activation, arranged so effective braking remains on at least 2 wheels if a method fails; or 2 independent brakes, each of which, when in operation, acts directly on at least half the number of wheels of the vehicle. The braking system of a heavy motor vehicle mentioned in subsection (1) that was built after 1945 must have a service brake operating on all wheels that, when applied— acts directly on the wheels and not through the vehicle’s transmission; or acts on a shaft between a differential of the vehicle and a wheel. The braking system of a heavy motor vehicle with 4 or more wheels must have a parking brake that— is held in the applied position by direct mechanical action without the intervention of an electrical, hydraulic or pneumatic device; and is fitted with a locking device that can hold the brake in the applied position; and has its own separate control. The parking brake mentioned in subsection (3) may also be the heavy motor vehicle’s emergency brake. If 2 or more independent brakes are fitted to a heavy motor vehicle with 4 or more wheels, the brakes must be arranged so brakes are applied to all the wheels on at least 1 axle of the vehicle when any brake is operated. In this section— independent brake , in relation to a heavy vehicle, means— a brake that is operated entirely separately from any other brake on the vehicle; or 2 or more brakes operated simultaneously by a drum, disc or part on which a shoe, band or friction pad makes contact, that is common to the brakes. (sch.2-sec.88-ssec.1) A heavy motor vehicle with 4 or more wheels built, or used, mainly for transporting goods or passengers by road must be fitted with— a braking system that— consists of brakes fitted to all wheels of the vehicle; and has at least 2 separate methods of activation, arranged so effective braking remains on at least 2 wheels if a method fails; or 2 independent brakes, each of which, when in operation, acts directly on at least half the number of wheels of the vehicle. (sch.2-sec.88-ssec.2) The braking system of a heavy motor vehicle mentioned in subsection (1) that was built after 1945 must have a service brake operating on all wheels that, when applied— acts directly on the wheels and not through the vehicle’s transmission; or acts on a shaft between a differential of the vehicle and a wheel. (sch.2-sec.88-ssec.3) The braking system of a heavy motor vehicle with 4 or more wheels must have a parking brake that— is held in the applied position by direct mechanical action without the intervention of an electrical, hydraulic or pneumatic device; and is fitted with a locking device that can hold the brake in the applied position; and has its own separate control. (sch.2-sec.88-ssec.4) The parking brake mentioned in subsection (3) may also be the heavy motor vehicle’s emergency brake. (sch.2-sec.88-ssec.5) If 2 or more independent brakes are fitted to a heavy motor vehicle with 4 or more wheels, the brakes must be arranged so brakes are applied to all the wheels on at least 1 axle of the vehicle when any brake is operated. (sch.2-sec.88-ssec.6) In this section— independent brake , in relation to a heavy vehicle, means— a brake that is operated entirely separately from any other brake on the vehicle; or 2 or more brakes operated simultaneously by a drum, disc or part on which a shoe, band or friction pad makes contact, that is common to the brakes.
