what does it mean if my Ford Mustang S550 (2015-2023) has uneven brake pad wear

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery to ensure safety while working on the brake system.

2. Remove Wheel

• Use a socket set to loosen the lug nuts.
• Elevate the vehicle with a jack and secure it on jack stands.
• Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

• Inspect Brake Pads:

  • Remove the caliper bolts with a socket wrench.
  • Carefully lift the caliper off the rotor and support it (do not let it hang by the brake line).
  • Remove the old brake pads and inspect for uneven wear.

• Replace Brake Pads:

  • If uneven wear is confirmed, replace all brake pads on the affected axle.
  • Apply brake grease to the backing plates of the new pads to reduce noise.
  • Install the new pads into the caliper bracket.

4. Check and Replace Calipers (if needed)

• If calipers are found to be sticking:
  • Remove the caliper from the bracket.
  • Disconnect the brake line and replace with a new caliper.
  • Reconnect the brake line, ensuring no leaks.

5. Reassemble and Test

• Reattach the caliper to the bracket and torque bolts to manufacturer specifications (typically around 20-30 ft-lbs).
• Reinstall the wheel and torque lug nuts to manufacturer specifications (usually around 100-120 ft-lbs).
• Lower the vehicle and reconnect the battery.
