Overview

This standard is about maintaining and repairing cycle hydraulic brake systems and faults. It is also about carrying out a quality check on the completed work before returning the cycle to the customer.  

In this standard the term ‘cycle’ includes pedal-propelled vehicles with two, three or four wheels. It may also include pedal-assisted e-bikes:
• Road legal up to 15.5 mph with a motor with an output of up to 250w
• E-cycles used for other purposes
