Wheel Clearance Check: CRITICAL! This kit is designed to fit most factory wheels. However, some 11-inch or 12-inch wheels may have tight clearance. Ensure your wheels have enough room to house the new calipers before final assembly.
Clean the Spindle: Before mounting the new caliper brackets, use a wire brush to remove all rust and debris from the original steering knuckles/spindles. A flat surface is essential for proper alignment.
Bleeding the Air: Converting from a drum system to a disc system means there is a lot of air in the lines. Use a vacuum bleeder if possible. Start with the caliper furthest from the master cylinder and be patient—disc brakes require a high-pressure, air-free line to feel firm.
Master Cylinder Compatibility: Your original drum brake master cylinder will work, but for the best performance and "feel," we recommend inspecting your master cylinder's condition. If it's old, this is the best time to refresh it.
Torque Specs: Use Blue Threadlocker (Loctite) on all mounting bolts. The vibrations from off-road riding can loosen brake components, so safety is paramount.

Notice:

Only fit for 12" and above wheel.

Not applicable with OEM aluminum wheel.

🔍 Troubleshooting Guide:

Issue	Possible Cause	Solution
Spongy Brake Lever	Air trapped in the lines or caliper.	Re-bleed the brakes. Ensure the bleeder valve is facing UP while bleeding. If it's facing down, air cannot escape.
Brake Rubbing/Dragging	Improperly seated caliper or pads.	Check the mounting bracket alignment. Ensure the wheel hub is fully seated and the axle nut is torqued to spec.
Reduced Braking Power	Pads not "bedded in" or greasy rotors.	New pads need a few stops to mate with the rotors. Clean the rotors with Brake Cleaner to remove any oily fingerprints from installation.
Wheel Won't Rotate	Caliper hitting the inside of the wheel.	You may need wheel spacers or different offset wheels. Check for interference between the caliper and the wheel weights.
Lever Goes to the Grip	Major leak or master cylinder bypass.	Check all banjo bolts and copper washers. If no leaks are found, the internal seals of your old master cylinder may be failing.
