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 3-23.
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 3-16 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.
