Drum Brakes
NOTE:
All rear drum brakes have a self-adjuster which is activated when brake pedal is applied as vehicle travels in reverse.
To manually adjust rear brakes, raise and support vehicle. Remove plug from adjustment hole in backing plate. Turn adjusting nut until shoes lock wheel. Back adjuster off until wheel turns freely or with very slight drag. Measured clearance between linings and braking surface of drum should be .024" (.60 mm).
