ONCE it is established that the pressure system is functioning correctly, be it hydraulic, vacuum or air-hydraulic or straight air-pressure, poor braking performance can only be attributed to the mechanical parts. Investigation into these sections of the system must be made largely by visual inspection and time saving is possible in only two ways.
The first and most obvious time-saver on this leg of the job is for the fitter concerned to be absolutely conversant with the units with which he is dealing. In a commercial vehicle workshop one will nearly always find fitters who excel when dealing with certain systems, and of course it pays to capitalise on this.
The speed with which a job can be done, however, depends la rgely on the equipment to hand, and this section deals with the various special tools that are available for overhauling and repairing units that have been found wanting during the investigation stages.
