my Skoda Octavia's rear brakes are squeaking, what could be wrong?

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is on a flat surface, and engage the parking brake.
• Wear safety glasses and gloves.

2. Lift the Vehicle

• Use a jack to lift the rear of the vehicle and secure it with jack stands.
• Remove the rear wheels using a socket set.

3. Remove Brake Components

• 3.1 Remove the brake caliper:
  • Use a socket to remove the caliper mounting bolts.
  • Carefully slide the caliper off the rotor and support it using a hook or bungee cord.
• 3.2 Remove the brake pads:
  • Slide the pads out of the caliper bracket.
• 3.3 Remove the rotor (if necessary):
  • If the rotor is stuck, tap it gently with a hammer to loosen it.

4. Inspect and Replace Parts

• 4.1 Inspect brake pads:
  • Replace if the material is below the minimum thickness (usually 3mm).
• 4.2 Inspect brake rotors:
  • Replace if they are worn beyond service limits or have deep grooves.
• 4.3 Replace hardware:
  • Replace any damaged or worn shims, clips, or caliper bushings.

5. Reassemble Components

• 5.1 Install new brake pads:
  • Slide the new pads into the caliper bracket.
• 5.2 Reinstall the brake caliper:
  • Position the caliper over the new pads and secure it with the mounting bolts. Torque to manufacturer specifications (typically around 30 Nm).
• 5.3 Reinstall the rotor (if removed):
  • Place the rotor back onto the hub.

6. Final Checks

• Reinstall the wheels and lower the vehicle.
• Tighten the lug nuts to the specified torque (usually around 100 Nm).
• Pump the brake pedal a few times to ensure proper pad seating.
