How to Change Brake Pad Mio i 125: A Step-by-Step Tutorial for Beginners

Are you looking for a comprehensive guide on how to change brake pads on your Yamaha Mio i 125? Look no further! This detailed guide will walk you through the process, step by step, ensuring a smooth and successful brake pad replacement. Whether you’re a seasoned mechanic or a first-time DIYer, this guide will equip you with the knowledge and confidence to tackle this essential maintenance task.

Why Change Your Brake Pads?

Brake pads are crucial components of your motorcycle’s braking system. They are responsible for slowing down your vehicle by creating friction against the brake rotors. Over time, brake pads wear down due to constant use, eventually reaching a point where they need to be replaced.

Failing to replace worn-out brake pads can lead to several problems, including:

• Reduced braking performance: Worn pads offer less friction, resulting in longer stopping distances and compromised safety.
• Damage to brake rotors: Metal-to-metal contact between the rotor and worn-out pads can cause grooves and damage, requiring costly repairs.
• Excessive noise: Worn pads can produce loud squealing or grinding noises, indicating a critical need for replacement.

Gathering Your Tools and Materials

Before embarking on the brake pad replacement, ensure you have the following tools and materials readily available:

• New brake pads: Purchase a set of brake pads specifically designed for your Yamaha Mio i 125. Ensure they are compatible with your motorcycle model.
• Torque wrench: A torque wrench is essential for tightening bolts to the manufacturer’s specifications, preventing overtightening and damage.
• Socket wrench set: You’ll need sockets of various sizes to loosen and tighten bolts.
• Pliers: Pliers are helpful for removing and installing brake pad retaining clips.
• Cleaning cloth: A clean cloth is necessary for wiping away dirt and debris.
• Brake cleaner: Use brake cleaner to thoroughly clean the brake caliper and rotor surfaces before installing new pads.
• Safety glasses: Protecting your eyes from debris is crucial during the repair process.
• Gloves: Wearing gloves will keep your hands clean and protect them from brake cleaner and grease.

Preparing Your Motorcycle

Before starting the brake pad replacement, it’s important to prepare your motorcycle for the task. Follow these steps:

• Park your motorcycle on a level surface: Ensure your motorcycle is stable and secure to prevent accidental movement during the repair.
• Engage the parking brake: This will help keep the rear wheel from rotating while you work on the brakes.
• Remove the rear wheel: Loosen the rear axle nut and remove the rear wheel to gain access to the brake caliper.

Removing the Old Brake Pads

Once the rear wheel is removed, you can proceed with removing the old brake pads. Follow these steps:

• Locate the brake caliper: The brake caliper is a metal housing that houses the brake pads and pistons.
• Remove the brake pad retaining clips: Use pliers to carefully remove the clips holding the brake pads in place.
• Remove the old brake pads: Gently pull the old brake pads out of the caliper.

Cleaning the Brake Caliper and Rotor

Before installing the new brake pads, it’s essential to thoroughly clean the brake caliper and rotor. Follow these steps:

• Clean the brake caliper: Use brake cleaner to remove any dirt, grease, or debris from the caliper. Pay close attention to the piston and its surrounding area.
• Clean the brake rotor: Use brake cleaner to clean the rotor surface, removing any rust or debris.

Installing the New Brake Pads

With the caliper and rotor clean, you can now install the new brake pads. Follow these steps:

• Insert the new brake pads: Carefully insert the new brake pads into the caliper, ensuring they are properly seated.
• Reinstall the brake pad retaining clips: Secure the new brake pads in place by reinstalling the retaining clips.
• Check for proper brake pad clearance: Ensure there is sufficient clearance between the brake pads and the rotor.

Reassembling the Rear Wheel

Once the new brake pads are installed, you can reassemble the rear wheel. Follow these steps:

• Install the rear wheel: Align the rear wheel with the axle and install the axle nut.
• Tighten the axle nut to the manufacturer’s specifications: Use a torque wrench to ensure the axle nut is properly tightened.
• Remove the parking brake: Release the parking brake to allow the rear wheel to rotate freely.
• Test the brakes: Apply the rear brake lever to ensure the brakes are working properly.

Final Steps and Maintenance Tips

After completing the brake pad replacement, it’s crucial to take a few final steps and follow maintenance tips to ensure optimal brake performance:

• Check for brake fluid level: Ensure the brake fluid level is within the recommended range.
• Lubricate brake caliper pins: Lubricate the caliper pins with brake grease to prevent corrosion and ensure smooth operation.
• Inspect brake components: Regularly inspect the brake pads, rotors, and other components for wear or damage.
• Maintain brake fluid: Flush and replace the brake fluid every two years or as recommended by the manufacturer.

The Importance of Safety

Remember that working on your motorcycle’s braking system requires caution and safety. Always follow these safety precautions:

• Wear safety glasses and gloves: Protect yourself from debris and chemicals.
• Work on a level surface: Ensure your motorcycle is stable and secure.
• Use the appropriate tools: Utilize the correct tools for the task.
• Follow the instructions carefully: Adhere to the steps outlined in this guide.
• Seek professional assistance: If you are unsure about any part of the process, consult a qualified mechanic.
