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 components.

Tools Required:

Jack and jack stands
Lug wrench
Brake caliper tool
Torque wrench
Pliers

2. Inspect and Replace Brake Pads

Remove the Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully lift the caliper off the rotor and secure it with a bungee cord or rope to avoid straining the brake line.
Inspect Brake Pads and Rotors:
- Check the brake pads for uneven wear and measure thickness.
- Inspect the rotors for grooves or warping; replace if necessary.
Install New Brake Pads:
- If pads are worn unevenly, replace them with high-quality pads from a reputable manufacturer.
- Ensure pads are fitted correctly in the caliper bracket.

3. Inspect and Replace Calipers (if necessary)

Check Caliper Operation:
- Manually compress the caliper piston using a brake caliper tool.
- Ensure it moves freely in and out; replace if it shows signs of sticking.
Install New Caliper:
- If replacement is needed, remove the brake line from the caliper.
- Install the new caliper and reconnect the brake line, ensuring no leaks.

4. Brake Fluid Service

Replace the brake fluid if contaminated or if the fluid level was low.
Bleed the brake system to remove any air pockets using a brake bleeder kit.

5. Reassemble and Torque

Reattach the brake caliper and ensure bolts are tightened to the manufacturer’s specified torque settings.
Reinstall the wheel and lower the vehicle.
