how to fix my Skoda Octavia's rear brakes grinding noise

Solution

1. Preparation

• Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, and a micrometer.
• Safety Warnings: Ensure the vehicle is on a flat surface and secure it with wheel chocks. Always wear safety glasses and gloves.

2. Raise the Vehicle

• Loosen the lug nuts of the rear wheels slightly while the car is on the ground.
• Use a jack to lift the rear of the vehicle and secure it with jack stands.
• Remove the rear wheels completely.

3. Remove Brake Components

• Brake Pads:

  • Remove the caliper bolts using a socket wrench.
  • Slide the caliper off the rotor and support it with a bungee cord or suitable method to avoid straining the brake line.
  • Remove the old brake pads from the caliper bracket.

• Brake Rotor:

  • If necessary, remove the caliper bracket by unscrewing its mounting bolts.
  • Slide the rotor off the wheel hub. If it is stuck, tap gently with a rubber mallet.

4. Inspect and Replace

• Inspect: Check the brake pads and rotors for wear; replace if below specifications.
• Replace:
  • Install new brake pads into the caliper bracket.
  • If the rotor is worn or damaged, replace it with a new rotor.
  • Apply brake grease to the back of the brake pads and on the caliper bracket contact points.

5. Reassemble

• Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications (usually around 25-35 Nm).
• Reinstall the wheel and torque the lug nuts in a crisscross pattern to the manufacturer's specifications (commonly around 100 Nm).

6. Final Checks

• Lower the vehicle safely off the jack stands.
• Pump the brake pedal several times to seat the brake pads against the rotor.
• Check brake fluid levels and top off if necessary.
