Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual inspection tool.
2
Check brake rotors for scoring or warping.
3
Measure brake pad thickness using a caliper or ruler.
4
Inspect brake calipers for proper operation and any signs of seizing.

Solution

1. Preparation

Tools Required: Wheel chocks, jack, jack stands, lug wrench
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Using the lug wrench, remove the lug nuts and take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
2. Carefully suspend the caliper using a hanger or bungee cord to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Check the thickness of the old pads; if they are below the manufacturer's specification (usually 3mm), replace them.
5. Install new brake pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotors for any grooves or warping using a straightedge or feeler gauge.
2. If the rotor surface is damaged, remove it by unbolting the rotor from the hub.
3. Install new rotors, ensuring they are correctly seated and torqued to manufacturer specifications.

6. Reassemble Brake Components

Reattach the caliper over the new brake pads and torque the caliper bolts to the specified torque (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground and fully tighten the lug nuts in a star pattern to ensure even pressure.

8. Test the Brakes

Pump the brake pedal a few times to seat the new pads against the rotor before driving.
