Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly with the lug wrench.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect the brake pads for uneven wear, and measure thickness.
If replacement is needed:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to prevent strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the pad contact points.
- Install new brake pads ensuring they are seated properly.

4. Inspect and Replace Caliper (if necessary)

If the caliper is found to be sticking:
- Remove the caliper from the bracket.
- Inspect the caliper piston for damage or corrosion.
- If needed, replace the caliper with a new one, ensuring proper alignment during installation.

5. Reassemble and Bleed Brakes

Reinstall the caliper and secure it with bolts to the specified torque value (typically around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten lug nuts to the manufacturer’s torque specification (usually 90-110 Nm).
Bleed the brakes using a brake bleeder kit to remove any air from the brake lines.
