Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

2. Inspect and Replace Brake Rotors

Remove Brake Caliper
- Use a socket set to unbolt the caliper from the bracket.
- Hang the caliper using a bungee cord to avoid straining the brake line.
Remove Brake Pads
- Slide the brake pads out of the caliper bracket.
Remove Brake Rotor
- If the rotor is secured by retaining screws, remove them using a screwdriver.
- Slide the rotor off the hub. If it’s stuck, tap gently with a rubber mallet.
Install New Brake Rotor
- Clean the hub surface with brake cleaner before installation.
- Slide the new rotor onto the hub and secure it with screws if applicable.

3. Install New Brake Pads

Insert New Brake Pads
- Apply brake grease to the backing of the new pads and install them into the caliper bracket.
Reattach Brake Caliper
- Position the caliper over the new pads and secure it with bolts.
- Torque the caliper bolts to manufacturer's specifications (typically around 25-30 Nm).

4. Brake System Bleeding

Bleed the brakes to remove any air using a brake bleeder kit.
Ensure to maintain proper fluid levels in the master cylinder.
