why does my Toyota RAV4 have uneven brake pad wear

Solution

1. Preparation

• Tools Required: Jack and jack stands, lug wrench, brake cleaner, caliper tool, torque wrench, socket set, safety glasses, and gloves.
• Safely lift the vehicle and secure it on jack stands. Remove the wheels to access the brake components.

2. Remove Brake Components

• Sub-steps:
  1. Remove the caliper bolts using the socket set.
  2. Carefully slide the caliper off the rotor and support it with a hanger or bungee cord to avoid straining the brake line.
  3. Remove the brake pads from the caliper bracket.
  4. If the rotor needs replacement, remove the caliper bracket and then the rotor.

3. Inspect and Replace Components

• Sub-steps:
  1. Inspect brake pads for uneven wear; replace any that are significantly worn.
  2. Check the caliper for proper operation; replace caliper if it is sticking or damaged.
  3. Ensure the brake rotor is not warped; replace if necessary.
  4. Clean and lubricate the caliper slide pins and contact points with brake grease to ensure smooth movement.

4. Reassemble Brake System

• Sub-steps:
  1. Reinstall the rotor (if removed) and torque to manufacturer specifications.
  2. Reinstall the caliper bracket and secure with bolts, torquing to specifications.
  3. Reinsert new or inspected brake pads into the caliper bracket.
  4. Reattach the caliper over the pads and secure it with bolts, torquing to specifications.

5. Final Checks

• Sub-steps:
  1. Reinstall the wheels and lower the vehicle.
  2. Pump the brake pedal to seat the pads against the rotors.
  3. Conduct a visual inspection to ensure all components are securely fastened and properly aligned.
