Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working on the braking system.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner
Remove the wheel using a socket set.
Inspect the brake pads for uneven wear or thickness below the manufacturer's specification.
If worn, remove the caliper bolts and slide the caliper off the rotor.
Replace the brake pads with new ones, ensuring they are properly seated.
Reinstall the caliper and torque the bolts to manufacturer specifications.

3. Inspect and Resurface/Replace Brake Rotors

Tools Required: Dial indicator, brake rotor tool, torque wrench
Check the brake rotors for warping using a dial indicator.
If the warping exceeds specifications, either resurface or replace the rotors.
To replace, remove caliper and caliper bracket, then remove the rotor.
Install the new or resurfaced rotor and reassemble the caliper and bracket, torquing to specifications.

4. Wheel Alignment Check

Tools Required: Alignment machine (typically performed at a shop)
Take the vehicle to a qualified alignment shop.
Check alignment settings against specifications and make necessary adjustments.

5. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, lug wrench
Inspect all tires for uneven wear or damage.
Ensure tires are inflated to the recommended PSI.
Replace tires if they show significant wear or damage.
