Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted using jack stands.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Remove the caliper mounting bolts using a socket set.
3. Carefully slide the caliper off the rotor and support it using a bungee cord (do not let it hang on the brake line).
4. Remove the old brake pads from the caliper bracket.
5. Inspect the backing plate of the pads for wear; replace if necessary.
6. Apply brake grease to the back of the new pads to reduce noise.
7. Install new brake pads into the caliper bracket.

3. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Check the rotor for any signs of scoring or uneven wear.
2. If the rotor is within specifications, it can be resurfaced; otherwise, replace it.
3. If replacing, remove the rotor by taking out the retaining screws and sliding it off the hub.
4. Install the new or resurfaced rotor onto the hub, ensuring it is flush against the surface.

4. Reassemble Brake Components

Sub-steps:
1. Slide the caliper back onto the rotor over the new pads.
2. Reinstall the caliper mounting bolts to the specified torque (usually 20-30 ft-lbs, check manufacturer specifications).
3. Reattach the wheel and hand-tighten the lug nuts.

5. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Pump the brake pedal to ensure proper pad seating and restore brake fluid pressure.
3. Perform a test drive to confirm the absence of the squealing noise.

Tools Required:
