it has been determined that chatter and brake pull are being caused by hard spots on the brake drum: Technician A say that the problem can be solved by grinding off the hard spots. Technician B says that the drum must be replaced. who is correct?
Which of the following statements about drum
brake shoes is not true?
a. Linings may be riveted or bonded to the shoes.
b. Shoe indentions hold the shoe in place
against the backing plate.
c. The shoe rim supports the shoe lining.
d. The primary/leading shoe is typically the one
that is positioned toward the front of the
vehicle.
During a brake inspection, the inner brake pad is found to be 3mm thick, while the outside pad is 8mm. Techinician A says this is a sign of a poorly lubricated hardware. Technician B says this is normal wear for brake pads.
