my Skoda Octavia's brakes squeal when I apply them, is that normal?

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is on a flat surface and securely lifted with jack stands.
• Disconnect the battery to avoid electronic issues during repair.

2. Remove Wheel

• Use a socket set to remove the lug nuts.
• Take off the wheel to access the brake assembly.

3. Inspect Brake Components

• Remove the caliper bolts using a socket.
• Carefully lift the caliper off the rotor; support it with a bungee cord or similar to avoid straining the brake line.
• Inspect brake pads for thickness; replace if less than 3mm.
• Check rotors for scoring or excessive wear; replace if necessary.

4. Replace Brake Pads

• If pads are worn, slide new brake pads into the caliper bracket.
• Apply brake grease to the back of the pads to prevent squealing.
• Ensure that shims and clips are in place.

5. Reassemble Brake System

• Reattach the caliper over the new pads and tighten caliper bolts to manufacturer specifications (typically around 25-30 Nm).
• Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

• Lower the vehicle from jack stands.
• Torque the lug nuts to the manufacturer's specifications (usually around 90-120 Nm).
• Reconnect the battery and perform a test drive to ensure brakes function properly.
