2.CONSTRUCTION AND FITTING REQUIREMENTS
2.1.General
2.1.1.Braking device
2.1.1.1.The braking device must be so designed, constructed and fitted as to enable the vehicle in normal use to comply with the provisions of this Directive, despite the vibration to which it may be subjected.
2.1.1.2.In particular, the braking device shall be so designed, constructed and fitted as to be able to resist the corroding and ageing phenomena to which it is exposed.
2.1.2.Functions of the braking device
The braking device defined in 1.2 must fulfil the following conditions:
2.1.2.1.Service braking
The service braking must make it possible to control the movement of the vehicle and to halt it safely, speedily and effectively, whatever its speed and load, on any up or down gradient. It must be possible to graduate this braking action. The driver must be able to achieve this braking action from his driving seat without removing his hands from the steering control.
2.1.2.2.Secondary (emergency) braking (where applicable)
The secondary (emergency) braking must make it possible to halt the vehicle within a reasonable distance in the event of failure of the service braking. It must be possible to graduate this braking action. The driver must be able to obtain this braking action from his driving seat while keeping at least one hand on the steering control. For the purposes of these provisions it is assumed that not more than one failure of the service braking can occur at one time.
2.1.2.3.Parking brake (if fitted)
The parking brake must make it possible to halt the vehicle stationary on up or down gradient even in the absence of the driver, the working parts being then held in the locked position by a purely mechanical device. The driver must be able to achieve this braking action from his driving seat.
2.2.Characteristics of braking devices
2.2.1.Every two-wheel moped or two-wheel motorcycle shall be equipped with two service braking devices, with independent controls and transmissions, one acting at least on the front wheel and the other at least on the rear wheel.
2.2.1.1.The two service braking devices may have a common braking so long as a failure in one braking device does not affect the performance of the other. Certain parts, such as the brake itself, the brake cylinders and their pistons (except the seals), the push rods and the cam assemblies of the brakes, shall not be regarded as liable to breakage if they are amply dimensioned, are readily accessible for maintenance and exhibit sufficient safety features.
2.2.1.2.A parking braking device is not compulsory.
2.2.2.Every motorcycle with sidecar shall be equipped with the braking devices which would be required if it had no sidecar; if these devices enable the required performance to be achieved in tests of the vehicle with sidecar, a brake on the sidecar wheel shall not be required; a parking braking device is not compulsory.
2.2.3.Every three-wheel moped must be equipped with:
2.2.3.1.either two independent service braking devices which together actuate the brakes on all of the wheels; or
2.2.3.2.a service braking device which operates on all the wheels, and a secondary (emergency) braking device which may be the parking brake.
2.2.3.3.In addition, every three-wheel moped must be equipped with a parking braking device acting on the wheel or wheels of at least one axle. The parking braking device, which may be one of the two devices specified in 2.2.3.1, must be independent of the device acting on the other axle or axles.
2.2.4.Every tricycle must be equipped with:
2.2.4.1.a foot-controlled serviced braking device which operates on all wheels, and a secondary (emergency) braking device which may be the parking brake; and
2.2.4.2.a parking braking device acting on the wheels of at least one axle. The control of the parking device must be independent of the control of the service braking device.
2.2.5.The braking devices must act on brake surfacespermanently connected to the wheels either rigidly or through components unlikely to fail.
2.2.6.The component parts of all braking devices, where attached to the vehicle, must be so secured that the braking devices do not fail in their function under normal operating conditions.
2.2.7.The braking devices shall operate freely when correctly lubricated and adjusted.
2.2.7.1.Wear of the brakes must be capable of being easily taken up by means of either manual or automatic adjustment. The brakes shall be capable of being adjusted to an efficient operating position until the brake linings have worn to the point of requiring replacement.
2.2.7.2.The control and the components of the transmission and of the brakes must possess a reserve of travel such that when the brakes become heated and the brake linings have reached maximum permitted degree of wear, effective braking is ensured without immediate adjustment being necessary.
2.2.7.3.When correctly adjusted the components of the braking device must not, when operated, contact anything other than the intended parts.
2.2.8.In braking devices where the transmission is hydraulic, the receptables containing the reserve fluid must be so designed and constructed that the level of the reserve fluid can be easily checked.
This provision does not apply to mopeds with a maximum speed of 25 km/h or lower.
