Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and securely lift it using a jack and jack stands.
Disconnect the battery if working on the electronic brake components.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake caliper tool, dial indicator.
Remove the wheel to access the brake assembly.
Inspect the brake rotors using a dial indicator to check for warping. If warping exceeds specifications, proceed to replace.
If replacing, remove the brake caliper bolts and the caliper itself, securing it away from the rotor.
Remove the old rotor by unscrewing any retaining screws if applicable.
Install the new rotor, ensuring it is properly seated and aligned.
Reinstall the brake caliper and torque the bolts to the manufacturer's specifications.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader.
While the caliper is removed, inspect the brake pads for thickness and uneven wear.
If worn down or damaged, remove the old brake pads from the caliper bracket.
Install new pads, ensuring they are correctly positioned.
Reassemble the caliper over the new pads and torque the bolts to the specified values.

4. Inspect Suspension Components

Tools Required: Wrench set, visual inspection tools.
Check control arms, bushings, and other suspension components for signs of wear or damage.
Replace any worn components as necessary, ensuring all bolts are torqued to specifications.
