Typical Causes of Squeaky Brakes on the 2021 Ford Explorer

Squeaky brakes can be a common issue in vehicles, including the 2021 Ford Explorer. Below are some typical causes of this problem, along with symptoms, diagnostic steps, tools required, and repair instructions.

Common Causes

1. Dust and Debris: Accumulation of dust, dirt, or debris between the brake pads and rotors.
2. Worn Brake Pads: Brake pads that are worn down to their wear indicators may produce a squeaking noise.
3. Moisture: Water or moisture can cause temporary squeaking, especially in humid conditions.
4. Glazed Brake Pads or Rotors: Overheating can cause the brake pads or rotors to become glazed, leading to a squeaking sound.
5. Lack of Lubrication: Insufficient lubrication on brake components can cause noise.
6. Faulty Brake Hardware: Worn or damaged hardware components, such as calipers or shims, can lead to squeaking.

Repair Instructions

Step 1: Raise the Vehicle

1. Park the vehicle on a flat surface, engage the parking brake, and turn off the ignition.
2. Loosen the lug nuts on the front wheels slightly.
3. Use the jack to lift the vehicle and secure it with jack stands.
4. Remove the front wheels.

Step 2: Inspect and Clean

1. Inspection:

   • Inspect the brake pads and rotors. Replace pads if they are less than 3mm thick or if they are glazed.
   • Check for debris and clean the area.

2. Cleaning:

   • Spray brake cleaner on the rotor and pads to remove dust and grime.
   • Use a soft brush if needed to scrub away any remaining particles.

Step 3: Check and Replace Brake Pads

1. If the brake pads are worn or damaged, remove the caliper by unscrewing the caliper bolts.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid stressing the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are seated properly.
5. Reinstall the caliper and torque the bolts to the manufacturer's specifications.

Step 4: Lubrication

1. Apply brake lubricant to the back of the brake pads and any contact points on the caliper and bracket to minimize noise.
2. Ensure that the anti-rattle clips (if equipped) are properly installed.

Step 5: Reassemble

1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.

Step 6: Test Drive

1. After completing the repair, perform a test drive to ensure the squeaking noise is resolved.
2. Monitor the brakes for any additional symptoms, such as grinding or reduced braking performance.
