why is my Skoda Octavia making a grinding noise when I brake

Solution

1. Preparation

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

2. Remove Wheel

• Sub-steps:
  1. Loosen the lug nuts on the wheel using a lug wrench.
  2. Raise the vehicle with a hydraulic jack and secure with jack stands.
  3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

• Sub-steps:
  1. Remove the brake caliper by unscrewing the caliper bolts with a socket set.
  2. Carefully slide the caliper off the brake rotor and support it with a hanger to avoid straining the brake line.
  3. Remove the old brake pads from the caliper bracket.
  4. Inspect the brake pads; if they are worn below the manufacturer’s specifications, replace them.
  5. Install new brake pads, ensuring they are positioned correctly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

• Sub-steps:
  1. Check the rotors for wear, scoring, or warping.
  2. If rotors are damaged, remove the caliper bracket bolts and slide off the bracket.
  3. Remove the old rotor by unscrewing any retaining screws if present.
  4. Install the new rotor, securing it in place with screws if applicable.

5. Reassemble Braking Components

• Sub-steps:
  1. Reattach the caliper over the new brake pads.
  2. Tighten the caliper bolts to the manufacturer’s torque specifications.
  3. Replace the wheel and hand-tighten the lug nuts.
  4. Lower the vehicle and tighten the lug nuts to the specified torque.

6. Final Checks

• Sub-steps:
  1. Pump the brake pedal a few times to seat the brake pads.
  2. Check brake fluid level and add as necessary.
