Step-by-Step Installation
1. Remove Components
-
Remove the front fork
-
Remove the front wheel
2. Prep the Fork for the Bracket
-
Place the brake bracket on the fork, as low as it will sit
-
Mark the center of all 4 bracket holes on the fork
-
Remove the bracket
-
Drill through the outside and inside walls of the fork at the marked points:
-
Start with a 1/8" bit
-
Follow with a 9/32" bit (or 1/4" if that’s what you have; it will be tight)
-
3. Mount the Bracket and Caliper
-
Mount the caliper and both brackets using the top left bolt hole:
-
Use one of the three longer M6 bolts to go through the upper bracket, fork, and lower bracket
-
Tighten hand tight for now
-
-
Next, install the lower left bolt (another long M6 bolt):
-
Goes through the upper bracket, lower bracket, and into the caliper
-
-
Install the third long bolt into the next lower hole to the right:
-
This one will use a nut on the back
-
-
The last two holes will use the shorter M6 bolts with nuts on the back
-
Tighten all five bolts to 75 in-lb of torque
4. Install the Rotor
-
Let the air out of the tire
-
Split the wheel by removing the four Allen head bolts
-
Replace the side without the sprocket using the new rotor half from your kit
5. Reassemble
-
Reinstall the wheel, carefully slipping the rotor into the caliper
-
Reinstall the fork onto the Crazy Cart
6. Cable and Brake Handle
-
Route the brake cable over to the drift bar
-
Install the brake handle on the bar
7. Fine-Tuning
-
Adjust the cable tension at the caliper first, then at the handle for fine-tuning
-
If needed, adjust the outer caliper pad using the small Allen set screw
