Introduction

Maintaining the braking system of your ATV is crucial for ensuring optimal performance and safety on and off the trails. One essential task in this regard is the removal of the rear disk brake, which may become necessary due to worn pads, a damaged rotor, or a leaking caliper. This guide will provide you with a comprehensive, step-by-step approach to removing the ATV's rear disk brake, along with valuable tips and insights to make the process seamless and efficient.

Step-by-Step Approach to ATV Rear Disk Brake Removal

Materials Required:

• ATV service manual
• 12mm and 14mm socket wrenches
• Torque wrench
• Brake cleaner
• Rags
• Safety glasses
• Gloves

Safety Precautions:

• Park the ATV on a level surface and engage the parking brake.
• Allow the brakes to cool down before starting the procedure.
• Wear appropriate safety gear, including gloves and safety glasses.

Step 1: Disconnecting the Brake Line

• Locate the brake line connecting to the caliper and use a 12mm socket wrench to loosen the banjo bolt.
• Carefully disconnect the brake line and allow the remaining fluid to drain into a container.

Step 2: Removing the Caliper Bracket

• Unscrew the two 14mm bolts securing the caliper bracket to the swingarm.
• Carefully lift the caliper bracket and the caliper assembly off the rotor.

Step 3: Removing the Brake Pads

• Inspect the brake pads for any uneven wear or damage.
• Use a flat-head screwdriver or a dedicated brake pad tool to press the caliper piston back into the caliper, creating clearance for removing the brake pads.
• Carefully remove the old brake pads.

Step 4: Removing the Rotor

• If applicable, remove the axle nut using a 17mm socket wrench and slide the axle out of the wheel hub.
• Use a 12mm socket wrench to remove the two bolts securing the rotor to the wheel hub.
• Carefully remove the rotor and inspect it for any damage or excessive wear.

Step 5: Cleaning and Inspecting Components

• Thoroughly clean the caliper, bracket, rotor, and brake pads with brake cleaner and rags.
• Inspect all components for any signs of damage, corrosion, or leaks.

Step 6: Reassembly

• Optional: Lubricate the caliper mounting pins with high-temperature brake grease.
• Install the new brake pads into the caliper and slide the caliper bracket back onto the rotor.
• Secure the caliper bracket with the 14mm bolts and torque them to the specifications provided in the ATV service manual.
• Connect the brake line to the caliper and tighten the banjo bolt using a 12mm socket wrench.
• Do not overtighten the banjo bolt.
• If the axle was removed, insert it back into the wheel hub and secure it with the axle nut, torquing it to the specified value.

Step 7: Bleeding the Brakes

• Use a vacuum bleeder or the traditional "pump and hold" method to bleed the brakes and remove any trapped air from the brake line.
• Refer to your ATV service manual for detailed instructions on bleeding the brakes.

Tips for Success

• Always consult your ATV service manual for accurate torque specifications and specific instructions for your model.
• Use high-quality replacement parts to ensure optimal performance and durability.
• If you encounter any difficulties or damage during the process, seek professional assistance from a qualified mechanic.
• Regularly inspect your ATV's rear disk brake system for any signs of wear or damage to ensure safe and effective braking.
