Problem Statement

Learn how to diagnose and repair the grinding noise when braking on a 2020 Ford Explorer. Step-by-step guide with symptoms, diagnostic steps, and tools required.

Affected Component

brake system

Estimated Time

2-3 hours

Symptoms

•A noticeable grinding noise when applying the brakes.
•Noise may increase with speed or pressure on the brake pedal.
•Possible vibrations felt in the brake pedal.
•Reduced braking performance or responsiveness.

Diagnostic Steps

1
Perform a thorough inspection of the brake components.
2
Measure the thickness of the brake pads using a caliper.
3
Check the rotors for scoring, grooves, or warping.
4
While the vehicle is stationary, apply the brake pedal gently and listen for grinding.
5
Inspect shims and clips for proper installation and condition.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Socket set and ratchet
•Torque wrench
•Brake caliper tool (if necessary)
•Caliper gauge or micrometer
•Dial indicator (for rotor inspection)
•Brake cleaner
•Safety goggles and gloves
•Jack and jack stands
•Lug wrench

Solution

Problem: Grinding Noise When Braking on a 2020 Ford Explorer

Possible Causes:

Worn brake pads.
Metal-to-metal contact between the brake pad and rotor.
Contaminated brake components (dirt, debris, or moisture).
Faulty brake hardware (shims, clips, or calipers).
Warped or damaged brake rotors.

Tools Required

Socket set and ratchet
Torque wrench
Brake caliper tool (if necessary)
Caliper gauge or micrometer
Dial indicator (for rotor inspection)
Brake cleaner
Safety goggles and gloves
Jack and jack stands
Lug wrench

Repair Instructions

Step 1: Safety Precautions

Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves during the repair.

Step 2: Raise the Vehicle

Loosen the lug nuts on the front wheels slightly while the vehicle is on the ground.
Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using the lug wrench.

Step 3: Inspect Brake Pads and Rotors

Remove the brake caliper bolts using the socket set and ratchet.
Carefully slide the caliper off the brake rotor (support it to avoid damaging the brake line).
Inspect the brake pads for wear. Replace if they are worn below 3mm.
Check the rotors for any visible damage or wear. Measure thickness and check for warping using the dial indicator.

Step 4: Replace Worn Parts

If brake pads are worn, remove them from the caliper bracket.
Install new brake pads, ensuring they are oriented correctly.
If rotors are damaged or worn, remove the old rotor by unbolting it from the hub.
Install new rotors, ensuring they are clean and free of debris.

Step 5: Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specifications using a torque wrench.
Reinstall the wheels and hand-tighten the lug nuts.

Step 6: Lower the Vehicle

Carefully lower the vehicle back to the ground.
Use the torque wrench to tighten the lug nuts to the specified torque setting (usually around 100-120 ft-lbs for most vehicles).

Step 7: Test the Brake System

Before driving, pump the brake pedal a few times to seat the brake pads against the rotors.
Test drive the vehicle at low speeds to ensure the noise has been resolved and brakes are functioning properly.

Conclusion

If the grinding noise persists after following these steps, further investigation may be necessary. Possible issues could involve the brake calipers, brake lines, or even the master cylinder. If unsure, consult a professional technician for a comprehensive diagnosis.
