Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lift it using jack stands.
Disconnect the battery to ensure safety while working on the braking system.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake cleaner
Socket set
OBD-II scanner (if needed)

2. Inspect Brake Components

Brake Pads:
- Remove the wheel using a lug wrench.
- Inspect the brake pads for uneven wear; replace if they are worn down unevenly.
Brake Rotors:
- Check the rotors for warping by measuring with a dial indicator or visual inspection.
- If warped, remove the rotors and either resurface them or replace with new rotors.

3. Examine Brake Calipers

Remove the caliper bolts using a socket set.
Inspect caliper movement; ensure it slides freely on the guide pins.
Clean and lubricate the caliper pins if they are sticking.
Replace calipers if there is significant damage or wear.

4. Check Wheel Alignment and Suspension

Inspect the suspension components (control arms, ball joints, tie rods) for wear.
If any components are worn, replace them to ensure proper alignment.
After repairs, it is recommended to have a professional alignment performed.

5. Reassemble and Test

Reinstall the brake components in reverse order, ensuring all bolts are torqued to manufacturer specifications.
Reconnect the battery.
Test drive the vehicle to confirm the issue has been resolved.
