Solution
1. Preparation
  • Gather tools and parts needed.
  • Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
  • Disconnect the battery to prevent electrical issues.
2. Remove Wheel Assembly
  1. Loosen the lug nuts on the wheel corresponding to the affected brake assembly while the wheel is still on the ground.
  2. Jack up the vehicle and secure it on jack stands.
  3. Remove the lug nuts completely and take off the wheel.
3. Inspect and Replace Brake Components
  1. Inspect Brake Pads:

    • Check for uneven wear. Replace if thickness difference exceeds 1mm.
    • Tools: Brake pad gauge, torque wrench.
  2. Inspect Brake Calipers:

    • Verify caliper movement; remove caliper bolts and slide the caliper off the rotor.
    • Clean and lubricate the caliper slide pins. Replace caliper if it’s seized.
    • Tools: Socket set, brake cleaner, grease.
  3. Inspect Brake Rotors:

    • Measure rotor thickness with a micrometer. Replace if below the manufacturer’s minimum spec.
    • Check for warping or damage. Resurface or replace as necessary.
    • Tools: Micrometer, rotor gauge.
  4. Inspect Suspension and Steering Components:

    • Check for worn bushings or ball joints. Replace any damaged parts.
    • Tools: Wrench set, torque wrench.
4. Reassemble Brake System
  1. Install new or refurbished brake pads into the caliper.
  2. Reattach the caliper to the bracket and torque bolts to manufacturer specifications.
  3. Reinstall the wheel and torque lug nuts in a star pattern.
  4. Reconnect the battery.
5. Final Checks
  • Pump the brake pedal to ensure proper caliper engagement.
  • Check brake fluid level and add fluid if necessary.
