68. Why is it very important that the Job Card is completed correctly?

Ans: “Since the job card becomes an official document, and it is used for legal documentation of vehicle’s
history. Job card is used to allocate labour and material to a particular mechanic. Job card in the case of
workshops helps the owners to have control on their mechanics. It is very useful to allocate work to the
mechanics. It serves as a register and proof for the work done by the mechanics”

many service brake failure indicator lamp should the vehicle have?

Ans: “The requirement in regards to how many service brake failure indicator lamp should the vehicle have is that It
shall have one or more service brake failure lamp indicator”

71. For vehicle fitted with a “Split Service Brake System”, the indicator lamp must activate whenever any of the
___________ conditions occur whilst the ignition switch is in the “engine on” position. What are those
conditions?

Ans:
 “At a speed of 10km/h, for a second pulses are not taken.
 At a speed of 20 km/h, there is a continuous noise in speed sensor signals
 Speed circuits are to be operated of 0.12 seconds or more.”

72. Braking and braking performance tests are based on?

Ans: “The performance of a braking system shall be determined by measuring the stopping distance in relation to
the initial speed of the vehicle and by measuring the mean fully developed deceleration during the test”

73. If you were to carry out any “Modification” tothe vehiclesbrake type or braking system, what is required to
get the modified vehicle braking system approved?

Ans: “In order to carry out anyModification” to the vehicles brake type or braking system, every modification
are needed to be approved by the authorities which will be approved on the basis of vehicle Firstly, with the
