          1. Remove a front wheel.
2. Measure the thickness of each brake pad.
3. If thickness of either brake pad is less than 1.0 mm
   (0.039 in.), the brake pads must be replaced.




                                                                                                           PR377B

                                                          Failure to properly burnish the brake pads could
                                                          lead to premature brake pad wear or brake loss.
                                                          Brake loss can result in severe injury.

                                                           1. Choose an area large enough to safely accelerate
