Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety gear, including gloves and eye protection.

2. Inspect and Replace Brake Rotors

Lift the Vehicle: Use a jack to lift the front of the car and support it with jack stands.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect Rotors: Measure rotor thickness and check for warping using a dial indicator.
- If warped or below minimum thickness, proceed to replace.
Remove Brake Caliper: Unscrew the caliper mounting bolts and carefully hang it using a bungee cord (do not let it hang by the brake line).
Remove Rotor: Unscrew the rotor retaining screws (if present), then slide the rotor off the hub.
Install New Rotor: Position the new rotor onto the hub, securing it with retaining screws.

3. Replace Brake Pads

Remove Old Pads: Slide out the old pads from the caliper bracket.
Compress Caliper Piston: Use a C-clamp to compress the caliper piston back into the housing.
Install New Pads: Place new pads into the caliper bracket, ensuring they are aligned correctly.

4. Reassemble Components

Reattach Caliper: Position the caliper over the new pads and secure it with the caliper mounting bolts. Torque to manufacturer's specifications (usually around 25-35 Nm).
Reinstall Wheel: Place the wheel back on, securing it with lug nuts. Torque to specifications (generally 90-120 Nm).
Lower Vehicle: Remove jack stands and lower the vehicle to the ground.

5. Brake Fluid Check

Inspect Brake Fluid Level: Check the brake fluid reservoir and top off with the recommended fluid (DOT 4 for most Volkswagen models).
Bleed Brakes: If necessary, bleed the brake lines to ensure no air is present.
