Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Use a jack to lift the vehicle and place jack stands for safety.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Sub-step 1: Check brake pads for thickness. Replace if less than 3mm.
Sub-step 2: Inspect rotors for wear. If they are scored or below the minimum thickness (usually 1mm), replace them.
Sub-step 3: Examine calipers to ensure they are functioning properly. Look for leaks or damage.

4. Replace Brake Pads and Rotors

Sub-step 1: If replacing pads, remove the caliper bolts using a socket set and slide the caliper off.
Sub-step 2: Remove old brake pads and install new ones, ensuring they are correctly positioned.
Sub-step 3: If replacing rotors, remove the rotor by unscrewing the retaining screws, if applicable, and replace it with a new one.
Sub-step 4: Reassemble the caliper over the new pads and torque caliper bolts to manufacturer's specification (usually around 20-30 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and torque lug nuts to the manufacturer's specification (usually around 76 ft-lbs).
Lower the vehicle and reconnect the battery.
Pump the brake pedal a few times to seat the pads before test driving.
