Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly before lifting the vehicle.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully loosening and taking off the lug nuts.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, socket set, impact wrench (optional).
Remove the caliper by unbolting it from the mounting bracket.
Suspend the caliper using a bungee cord to avoid straining the brake line.
Remove the brake pads from the caliper bracket.
Unbolt and remove the rotor from the hub; check for warping using a dial indicator.
If warped, replace with new rotors. Torque the rotor bolts to the manufacturer’s specifications.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads. If they are worn down, replace them.
Clean the caliper bracket and apply brake grease to the pad backing and caliper slide points.
Install the new brake pads into the caliper bracket.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Torque the caliper bolts to specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

6. Check Suspension Components

Inspect and replace any worn or damaged suspension components as necessary.
Ensure that all bolts are torqued to specifications.
