Solution

1. Preparation

Tools Required: Socket set, jack stands, lug wrench, brake cleaner, safety goggles, gloves.
Jack up the vehicle and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Take out the old brake pads from the caliper bracket.
Inspect the old pads for uneven wear or damage; replace them if necessary.
Clean the caliper bracket with brake cleaner to remove any debris.

3. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for any deep grooves or warping.
If the rotor is damaged, remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
Install new rotors by aligning them with the hub and securing them with screws.
Ensure they are properly torqued to the manufacturer specifications (usually around 70-80 ft-lbs).

4. Reassemble Braking System

Reinstall the new brake pads into the caliper bracket.
Slide the caliper back over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
Pump the brake pedal several times to seat the brake pads against the rotors before driving.
