Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Raise Vehicle

Use a jack to lift the front or rear (depending on the squeaking location) of the vehicle.
Secure with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Keep the lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If less than 3mm, they should be replaced.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and secure it without stressing the brake line.
- Remove the old pads.
- Install new pads, ensuring they are seated properly.

5. Inspect and Replace Brake Rotors (if needed)

Inspect Brake Rotors:
- Look for any grooves or signs of warping on the rotor surface.
Replace Brake Rotors:
- If damaged, remove the rotor by unscrewing the retaining screws (if present) and sliding the rotor off the hub.
- Install the new rotor, ensuring it is flush against the hub.
- Tighten retaining screws to manufacturer's specifications.

6. Reassemble and Test

Reinstall the brake caliper and secure with bolts, ensuring proper torque (usually around 25-30 Nm).
Reinstall the wheel and tighten lug nuts in a crisscross pattern to the specified torque (typically 100-120 Nm).
Lower the vehicle and pump the brake pedal to seat the new pads.

Tools Required:

Socket set
Torque wrench
Brake pad spreader tool
Jack and jack stands
Safety gloves and goggles

Parts Required:

Brake pads
Brake rotors (if necessary)

Estimated Repair Time: 2-4 hours

Safety Warnings:
