Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual check.
2
Check brake rotors for scoring or damage by removing the wheel.
3
Inspect brake calipers for proper operation and signs of leakage.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, safety goggles, gloves.
Sub-steps:
1. Park the vehicle on a flat surface and engage the parking brake.
2. Loosen the lug nuts on the front wheels slightly while the vehicle is still on the ground.
3. Jack up the vehicle and secure it with jack stands.
4. Remove the front wheels.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper off the rotor and support it using a bungee cord or similar device (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pad backing for wear indicators; replace pads if they are worn down to the indicator.
5. Apply brake grease to the back of the new pads to prevent noise, then install them in the caliper bracket.

3. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Check the surface of the rotors for scoring or damage.
2. If the rotors are scored, consider having them resurfaced or replaced as needed.
3. Clean the rotor surfaces with brake cleaner to remove dust and debris before reassembly.
4. Install the rotor back onto the hub if resurfacing is not required.

4. Reassemble Brake Components

Sub-steps:
1. Reposition the caliper over the new brake pads.
2. Tighten the caliper bolts to manufacturer specifications (typically around 25-35 ft-lbs).
3. Reinstall the wheels and tighten the lug nuts in a star pattern to ensure even pressure.
4. Lower the vehicle and torque the lug nuts to the specified value.

5. Final Checks

Sub-steps:
1. Pump the brake pedal several times to seat the pads against the rotors.
2. Check brake fluid level in the master cylinder and top off if necessary.
3. Test drive to ensure the grinding noise is resolved and brakes function correctly.
