Regularly inspect
caliper for Running
Clearance:
• Stop the vehicle on level ground
and let the brakes cool down. Hot
brake calipers can burn skin on
contact.
• Chock the wheels.
• Temporarily release the parking
brakes.
• Grab the caliper and move it. This
movement is Running Clearance.
• Proper Running Clearance is
0.08 inch (2
mm) of movement of
the brake caliper (approximately
the thickness of a nickel) in the
inboard/outboard direction.
• Have a qualied mechanic provide
further inspection if the caliper
does not move or appears to move
more than the specied clearance.
