  1. Prepare the Vehicle:

    • Park your Tiguan on a level surface and engage the parking brake. This prevents the vehicle from rolling while you are working on the brakes.
    • Loosen the lug nuts on the wheel you'll be working on. Don't remove them completely yet! Loosening the lug nuts before lifting the vehicle makes it easier to remove the wheel once it's in the air.
    • Place wheel chocks behind the rear wheels to prevent any accidental rolling.

  2. Lift and Secure the Vehicle:

    • Consult your owner's manual for the correct jacking points. Using the correct jacking points prevents damage to the vehicle's frame or undercarriage.
    • Lift the vehicle with the jack and securely place jack stands under the frame. Never work under a vehicle supported only by a jack! Jack stands provide a stable and secure support, ensuring your safety while working underneath the vehicle.
    • Carefully lower the vehicle onto the jack stands, ensuring they are properly positioned.
    • Remove the wheel.

  3. Remove the Old Brake Pads:

    • Locate the brake caliper. The brake caliper houses the brake pads and presses them against the rotor to stop the vehicle.
    • Remove the brake caliper bolts. These bolts hold the caliper in place. Note their position for reassembly. Knowing the exact position of the bolts will simplify the reassembly process.
    • Carefully slide the caliper off the rotor. Be careful not to damage the brake line.
    • If your Tiguan has a brake pad wear sensor, disconnect it from the old brake pad. Gently disconnect the sensor to avoid damaging the connector or wiring.
    • Remove the old brake pads from the caliper bracket. The brake pads slide into the caliper bracket. Note their orientation for installing the new pads.

  4. Compress the Caliper Piston:

    • Use the brake caliper tool to compress the piston back into the caliper. This creates space for the new, thicker brake pads. Compressing the piston is essential for installing the new brake pads without difficulty.
    • Follow the tool's instructions carefully to avoid damaging the piston. Do not force it! Forcing the piston can cause internal damage and compromise the braking system.

  5. Clean and Lubricate:

    • Clean the brake caliper bracket and rotor with brake cleaner. This removes dirt, grease, and brake dust, ensuring optimal braking performance.
    • Apply brake grease to the caliper slides. Lubricating the caliper slides allows the caliper to move freely, ensuring even brake pad wear and preventing noise.

  6. Install the New Brake Pads:

    • Install the new brake pads into the caliper bracket. Ensure they are properly seated and aligned. Correctly installing the brake pads ensures proper contact with the rotor and prevents uneven wear.
    • If your Tiguan has a brake pad wear sensor, attach it to the new brake pad. Properly connecting the wear sensor is crucial for it to function correctly and alert you when the brake pads are nearing replacement.

  7. Reassemble the Caliper:

    • Carefully slide the caliper back onto the rotor, aligning it with the bracket. Be careful not to damage the brake line during reassembly.

    • Repeat the entire process for the other front wheel.

  10. Break-In the New Brakes:

    • After installing new brake pads, it’s crucial to break them in properly. This involves a series of controlled stops that gradually heat up the pads and rotors, optimizing their performance and lifespan. Find a safe, open area where you can perform these steps without endangering yourself or others.
    • Start by driving at a moderate speed, around 30 mph (50 km/h), and gently apply the brakes to slow down to about 10 mph (15 km/h). Repeat this process about five to six times. This initial phase helps to seat the pads against the rotors.
    • Next, increase your speed to around 45 mph (70 km/h) and apply the brakes more firmly, slowing down to about 15 mph (25 km/h). Repeat this step approximately four to five times. Applying the brakes more firmly helps to transfer friction material from the pads to the rotors, which is essential for optimal braking performance.
    • Allow the brakes to cool down for a few minutes after completing these steps. You can do this by driving at a steady speed without using the brakes excessively.
    • Avoid hard or abrupt stops during the first 200 miles (320 kilometers) after replacing your brake pads. This allows the pads and rotors to fully mate and ensures even wear.
    • Be aware that you might notice a slight burning smell or some noise from the brakes during the break-in period. This is normal and should dissipate as the pads and rotors settle in.
    • Following the break-in procedure ensures that your new brake pads will deliver consistent and reliable braking performance, extending their lifespan and enhancing your safety on the road.
