LEARANCE
There should be equal pad clearance on both sides of the rotor. If the pads touch the
rotor during a run, the information provided by the dyno will be inaccurate. Use the
following steps to adjust the clearance.
1
Loosen the brake caliper stop bolts.
2
Insert the brake adjusting shim between the inboard brake pad and the brake
rotor. Refer to Figure 3-18.
3
Remove the hairpin cotter and hand tighten the castle nut on the caliper assembly
to clamp the brake pads against the rotor and shim. Refer to Figure 3-11 for
hairpin and castle nut location.
4
Tighten the brake caliper stop bolts.
5
Loosen the castle nut and remove the shim.
6
Adjust the clearance between the outboard brake pad and rotor. Loosen the castle
nut to increase the clearance.
There should be equal space on both sides of the rotor.
7
Replace the hair pin cotter in the castle nut.
Note:
Cycle the brake to verify the brake pads release far enough so they do not
touch the rotor. If the pads touch the rotor during a run, the information provided
by the dyno will be inaccurate.
