why does my Volkswagen Golf MK5 (2004-2008) vibrate when I brake?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.
• Disconnect the battery for safety.

2. Inspect Brake Components

• Sub-steps:

  1. Remove the wheel using a lug wrench.
  2. Inspect the brake rotor for any signs of warping (use a dial gauge if available).
  3. Check for any surface rust or grooves on the rotor.

• Tools Required: Lug wrench, dial gauge (optional)

3. Replace or Resurface Rotors

• Sub-steps:

  1. If the rotors are warped, remove the caliper by unbolting it from the mounting bracket.
  2. Remove the rotor from the hub.
  3. If resurfacing is possible, have it done at a machine shop; otherwise, replace with new rotors.
  4. Install the new or resurfaced rotor and reattach the caliper.

• Tools Required: Socket set, torque wrench

• Torque Values: Refer to the vehicle service manual for caliper and wheel nut torque specifications.

4. Inspect and Replace Brake Pads

• Sub-steps:

  1. Check the brake pads for uneven wear and replace if necessary.
  2. Clean the caliper bracket and apply anti-squeal grease on the back of the new pads.
  3. Install the new pads and reassemble the caliper.

• Parts Required: New brake pads if necessary

5. Reassemble and Lower Vehicle

• Sub-steps:
  1. Reinstall the wheel and tighten the lug nuts to the specified torque.
  2. Lower the vehicle from the jack stands.
  3. Reconnect the battery.
