Solution

1. Preparation

Tools Required: Jack stands, lug wrench, brake cleaner, torque wrench, OBD-II scanner.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Brake Pads

Remove the wheel using the lug wrench.
Inspect the brake pads for wear. If they are worn unevenly or below the manufacturer's specifications, replace them.
To remove the pads, unbolt the caliper using the appropriate socket.
Slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Remove the old brake pads and clean the caliper bracket with brake cleaner.
Install new brake pads ensuring they are properly seated.

3. Inspect and Replace Brake Rotors

While the wheel is off, check the brake rotors for warping or scoring using a straight edge or rotor gauge.
If rotors are damaged, unbolt them from the hub and remove them.
Install new rotors, ensuring they are torqued to manufacturer specifications (typically 70-100 lb-ft).
Reattach the caliper and ensure all bolts are tightened to specifications.

4. Caliper Inspection

Check the brake caliper for any signs of sticking or corrosion.
If necessary, rebuild or replace the caliper. Use new seals and lubricate the caliper pins.
Reinstall the caliper and ensure proper movement of the caliper during braking.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to specifications (typically 80-100 lb-ft).
Reconnect the battery.
Test the brakes by gently applying pressure to the pedal and checking for smooth engagement.
