how to diagnose uneven brake pad wear on Tesla Model 3 Highland (2024-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Secure the vehicle on a flat surface and engage the parking brake.
• Wear appropriate safety gear (gloves, goggles).

2. Lift the Vehicle

• Use a jack to lift the vehicle and secure it with jack stands.
• Remove the wheel to access the brake assembly.

3. Remove Brake Components

• Remove Brake Caliper:
  • Use a socket set to unbolt the caliper from the bracket.
  • Carefully hang the caliper using a bungee cord to avoid straining the brake line.
• Remove Brake Pads:
  • Slide the brake pads out of the caliper bracket.

4. Inspect and Replace

• Inspect Brake Pads:
  • Check for uneven wear; replace any worn pads with new ones.
• Inspect Brake Rotors:
  • Measure rotor thickness; replace if below manufacturer specifications.
  • Check for signs of warping or scoring; replace if necessary.
• Inspect Calipers:
  • Check for proper operation; replace if calipers are sticking or damaged.

5. Reassemble

• Install New Brake Pads:
  • Apply anti-squeal lubrication to the back of the pads and install new pads into the caliper bracket.
• Reattach Brake Caliper:
  • Position the caliper over the new pads and secure with bolts.
  • Torque bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).

6. Final Checks

• Reinstall the wheel and lower the vehicle.
• Pump the brake pedal to ensure proper pad seating.
