Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Raise the vehicle on a flat surface and secure it with jack stands.
Remove the wheels using the lug wrench.

2. Remove Brake Components

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or wire (do not let it hang by the brake line).
3. Remove the brake pads from the caliper bracket.

3. Inspect and Replace Parts

Sub-steps:
1. Inspect the brake pads; if they are worn down to the metal, replace them with new pads.
2. Check the rotors for any scoring or warping; if damaged, replace or resurface them.
3. Clean the caliper and bracket with brake cleaner to remove dust and debris.
4. If calipers are malfunctioning, consider replacing them.

4. Reassemble Components

Sub-steps:
1. Install new brake pads into the caliper bracket.
2. Reattach the caliper over the new pads and secure it with caliper bolts.
3. Replace the wheel and tighten the lug nuts by hand.

5. Lower Vehicle and Final Checks

Sub-steps:
1. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
2. Pump the brake pedal to seat the new pads before driving.
