Insert a screwdriver into the hole and rotate the adjuster in the direction
of the arrow in the illustration until it locks up the rotor.
To set the proper clearance, rotate the adjuster 3–5 notches in the
opposite direction. With adjuster rotated 4 notches, the shoe clearance will
be 0.013 inch (0.32mm).
Verify that the brakes do not drag when rotating the rotor by hand.
