Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the 12V battery to prevent electrical issues.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner, brake pad spreader.
Remove the wheel to access the brake assembly.
Use a socket set to remove caliper bolts and detach the caliper from the rotor.
Inspect brake pads for wear; if the friction material is below the manufacturer's specification, replace them.
Apply brake cleaner to the caliper and rotor to remove dust and debris.
Install new brake pads, ensuring they are seated properly.

3. Inspect and Replace Rotors (if necessary)

Check the rotor surface for warping or scoring; replace if out of specification.
Tools Required: Rotor puller (if necessary), torque wrench.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor and secure it with the retaining screws.
Torque the screws to the manufacturer’s specifications.

4. Inspect Suspension Components

Tools Required: Jack and jack stands, torque wrench.
Lift the vehicle with a jack and secure it with jack stands.
Visually inspect control arms, tie rods, and bushings for signs of wear and damage.
Replace any worn or damaged components as necessary.

5. Reassemble and Test

Reinstall the brake caliper and wheel.
Use a torque wrench to tighten lug nuts to the manufacturer’s specifications.
Reconnect the battery and lower the vehicle.
Test the brakes at low speeds to ensure proper function and check for vibrations.
