why does my Volkswagen Passat B8 (2015-2022) smell like burning when I brake?

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Gather necessary tools and parts.

2. Inspect and Replace Brake Pads

• Sub-steps:
  • Remove the wheel using a lug wrench.
  • Use a socket set to unbolt the caliper and slide it off the rotor.
  • Remove the old brake pads from the caliper bracket.
  • Inspect the caliper for any signs of damage or fluid leaks.
  • Install new brake pads, ensuring proper orientation.
  • Reinstall the caliper and torque the bolts to manufacturer specifications (typically 25-35 Nm).
  • Repeat for the opposite wheel if necessary.

3. Check and Replace Brake Rotors (if required)

• Sub-steps:
  • If rotors show signs of scoring or warping, remove them using appropriate socket tools.
  • Clean the hub surface to ensure proper rotor seating.
  • Install new rotors, making sure they are oriented correctly.
  • Torque the rotor bolts to spec (usually 100-120 Nm).

4. Replace Brake Fluid (if contaminated)

• Sub-steps:
  • Locate the brake fluid reservoir and remove the cap.
  • Using a brake bleeder kit, bleed each brake line starting from the furthest wheel.
  • Replace with fresh brake fluid as specified by the manufacturer (usually DOT 4).
  • Check for proper brake function after bleeding.

5. Reassemble and Test

• Sub-steps:
  • Reinstall the wheel and hand-tighten the lug nuts.
  • Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 100-120 Nm).
  • Conduct a test drive to ensure proper braking performance and check for any remaining odors.

Tools Required:

• Lug wrench
• Socket set
• Torque wrench
• Brake bleeder kit
• Screwdriver set

Parts Required:

• Brake pads
• Brake rotors (if necessary)
• Brake fluid (DOT 4)

Estimated Repair Time: 2-4 hours

Safety Warnings:

• Always wear safety glasses and gloves when working on the braking system.
• Allow the vehicle to cool down if brakes have been used extensively before starting work.
