Lesson l/Learning Event 3
ROAD-TEST INSPECTION
Roadtest the vehicle and check the operation of the brakes by
stopping several times while traveling on a smooth road. Check for
squeaking or grinding sounds when the brakes are applied, an
excessive amount of pressure required on the brake pedal to stop the
vehicle, and the vehicle pulling to one side when the brakes are
applied (uneven braking).
If the brakes make a squeaking or grinding sound, some of the more
common causes are:
Glazed or worn lining.
Lining loose on the brake shoes.
Dirt embedded in the lining.
Improper adjustment.
Brake fluid or grease on the lining.
Scored brake drums or rotors.
NOTE
The wheel and brake drum will have to be removed
from the noisy brake and the brake parts
inspected to determine the exact cause of the
noise.
When excessive pressure must be applied to the brake pedal to stop
the vehicle, any one or more of the following items may be the cause:
Glazed or worn brake lining.
Improperly adjusted brake shoes.
Dirt in the brake drums.
Grease or brake fluid on the lining.
Faulty master cylinder.
Binding pedal linkage.
Restricted brake line.
AFTER ROAD-TEST INSPECTION
If such things as pulling to one side or poor braking action are
noted during a road test, an after roadtest inspection is done.
