Brake Drum: Testing and Inspection
Servicing the front brakes will usually correct pulsation in the brake pedal. Service the rear brakes only if the problem persists.
In order to determine if the front or rear brakes are at fault, drive the vehicle at low speed in an area away from people and moving traffic (such as a large
parking lot). Apply the parking brake and feel for the pulsation. If a pulsation is not noticed, the fault is probably in the front brakes. When the brake
drums are removed, thoroughly clean and inspect the drums for the following conditions:
^
Cracks
^
Scores
^
Deep grooves
^
Out-of-round
^
Taper
Normal, light scoring of brake drum surfaces not exceeding 1.2 mm (0.050 in.) in depth will not affect brake operation.
