Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Brake cleaner
Torque wrench
C-clamp or brake caliper tool

Parts Required:

New brake pads
New brake rotors (if necessary)
Brake fluid (if needed)

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Remove Brake Components

Inspect Brake Pads: Check for wear; if they are less than 1/4 inch thick, they should be replaced.
Remove Brake Caliper:
- Locate the caliper mounting bolts and remove them using a socket.
- Carefully slide the caliper off the rotor and support it with a bungee cord or hang it to avoid stressing the brake line.
Remove Brake Pads: Slide the old brake pads out of the caliper bracket.

4. Replace Brake Pads and Rotors (if necessary)

Install New Brake Pads:
- Place the new pads into the caliper bracket in the same position as the old ones.
Replace Rotors (if required):
- Remove the rotor by unscrewing any retaining screws and then sliding it off the hub.
- Install the new rotor, ensuring it is seated properly.

5. Reassemble Brake Components

Reattach Caliper:
- Use the C-clamp or brake caliper tool to compress the caliper piston, allowing it to fit over the new pads.
- Slide the caliper back into position and torque the mounting bolts to the manufacturer’s specifications (usually around 20-25 ft-lbs).
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 100-150 ft-lbs).

6. Final Checks

Check brake fluid level and add fluid if necessary.
Pump the brake pedal a few times to ensure proper brake engagement.
