Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and safely lifted using jack stands.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, dial indicator.
Remove the wheel to access the brake assembly.
Use a dial indicator to check the rotor for runout; if warped beyond specifications, proceed to replace.
Remove the caliper by unbolting it and support it with a bungee cord to avoid strain on the brake line.
Remove the rotor by unbolting it from the hub.

Sub-steps:

Clean the hub surface with brake cleaner.
Install the new rotor, ensuring it is seated properly.
Reattach the caliper and torque bolts to the manufacturer’s specifications (usually around 25-30 Nm).
Reinstall the wheel and torque lug nuts to specification (typically 110 Nm).

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, socket set, torque wrench.
Check the brake pads for thickness; if they are below specifications, replace them.

Sub-steps:

Remove the caliper bracket if necessary to access the pads.
Use a brake pad spreader to compress the caliper piston.
Replace the old pads with new ones, ensuring they are properly aligned.
Reassemble the caliper and torque bolts to specifications.

4. Inspect Suspension Components

Tools Required: Wrench set, pry bar.
Check control arms and bushings for wear or damage.

Sub-steps:

Use a pry bar to check for play in the bushings.
Replace any worn components as necessary.
Ensure all bolts are tightened to manufacturer specifications.
