7.) During normal braking, the technician observes a pulsation in the brake pedal each time the brakes are applied. The brake pedal pulsation could indicate:
OA. normal ABS brake system operation.
OB. excessive lateral runout in the rotors.
OC. a loose brake pedal assembly.
OD. a leaking proportioning valve.



Answer :

Final answer:

Excessive lateral runout in the rotors could cause the observed brake pedal pulsation during normal braking due to disruption in force transmission through Pascal's principle.


Explanation:

Excessive lateral runout in the rotors could cause the brake pedal pulsation observed during normal braking. This issue leads to uneven braking and causes the pedal to pulsate as the brakes are applied.

Hydraulic brakes use Pascal's principle to transmit force from the brake pedal to the brake pads. When there is a problem like excessive lateral runout in the rotors, it can disrupt this transmission of force and result in the observed pulsation.

Friction between the brake pad and rotor surfaces is essential for braking; any deviation in this interaction, such as due to rotor runout, can cause pulsation in the brake pedal.
