Common Brake Problems with the 2020 Ford Explorer

The 2020 Ford Explorer, part of the sixth generation (U625), may experience several common brake problems. Below are the common symptoms, diagnostic steps, tools required, and repair instructions for addressing these issues.

1. Symptoms of Brake Problems

• Squeaking or Grinding Noises: Sounds coming from the brakes when applying pressure.
• Reduced Brake Performance: Longer stopping distances or a spongy brake pedal feel.
• Brake Warning Light: Illuminated brake warning light on the dashboard.
• Vibration or Pulsation: Feeling vibrations through the brake pedal when braking.
• Uneven Brake Wear: Noticeable wear on brake pads or rotors.

2. Common Brake Problems

• Worn brake pads
• Warped brake rotors
• Brake fluid leaks
• Faulty brake calipers
• Malfunctioning brake master cylinder

3. Diagnostic Steps

1. Visual Inspection:

   • Inspect the brake pads for wear. Minimum thickness is typically around 3mm.
   • Check the rotors for scoring, warping, or discoloration.
   • Look for any signs of fluid leaks around brake lines, calipers, and the master cylinder.

2. Listen for Noises:

   • While driving slowly, listen for any squeaking or grinding noises when applying brakes.

3. Brake Fluid Check:

   • Check the brake fluid level in the reservoir. If low, inspect for leaks.

4. Brake Pedal Feel:

   • Test the brake pedal for firmness. A spongy feel may indicate air in the brake lines or a failing master cylinder.

5. Test Drive:

   • Perform a test drive to assess braking performance and listen for any abnormal sounds or vibrations.

4. Tools Required

• Socket set
• Torque wrench
• Brake cleaner
• C-clamp or brake caliper tool
• Brake pad spreader
• Screwdriver set
• Pliers
• Brake fluid
• Diagnostic scanner (optional for electronic issues)
• Safety glasses and gloves

5. Repair Instructions

A. Replacing Worn Brake Pads

1. Lift the Vehicle:

   • Use a jack to lift the front or rear of the vehicle and secure it on jack stands.

2. Remove the Wheel:

   • Use a socket wrench to remove the lug nuts and take off the wheel.

3. Remove Brake Caliper:

   • Use a socket to remove the caliper bolts. Carefully lift the caliper off the rotor and support it with a bungee cord or rope. Do not let it hang by the brake line.

4. Remove Old Brake Pads:

   • Slide the old brake pads out of the caliper bracket.

5. Compress the Caliper Piston:

   • Use a C-clamp or brake caliper tool to gently push the piston back into the caliper housing to make space for the new pads.

6. Install New Brake Pads:

   • Insert the new brake pads into the caliper bracket.

7. Reattach Brake Caliper:

   • Position the caliper back over the new pads and secure it with the caliper bolts.

8. Reinstall Wheel:

   • Place the wheel back on and hand-tighten the lug nuts. Lower the vehicle and torque the lug nuts to manufacturer specifications.

B. Replacing Warped Brake Rotors

1. Follow Steps 1-3 Above.

2. Remove Old Rotor:

   • If the rotor is held by retaining screws, remove them. Slide the rotor off the hub.

3. Install New Rotor:

   • Clean the new rotor with brake cleaner to remove any protective coating. Mount the new rotor onto the hub.

4. Follow Steps 5-8 Above.

C. Brake Fluid Leak Repair

1. Identify Leak Source:

   • Inspect brake lines, calipers, and the master cylinder for any visible leaks.

2. Replace Damaged Components:

   • If a line is damaged, replace it with a new brake line. For calipers or the master cylinder, follow the removal and installation procedures for those components.

3. Bleed the Brake System:

   • After any brake component replacement, bleed the brake lines to remove air. Start at the wheel farthest from the master cylinder and work your way to the closest.

6. Final Checks

• After repairs, perform another test drive to ensure the brakes are functioning properly.
• Check for any warning lights on the dashboard after the repair.

Conclusion

Regular maintenance and prompt attention to brake issues are crucial for safety and performance. If you are unsure or uncomfortable with any of the repair steps, it is advisable to seek professional assistance.
