Service
1. Replace front brake pads with updated brake pads (part number 4G0698151K) according to Elsa.
2. Apply a thin coat of anti-seize (G 052560A2)
lubricant to the guide pins of the front caliper
carriers (Figure 2).

Figure 2. Caliper carrier guide pins with anti-seize (G
052560A2) lubricant applied where the pads make
contact.
3. Check the part number on the front discs. If the
part number is not 4G0615301G, then install
4G0615301G or 4G0615301Q front discs, or any
supersession available in ETKA (Figure 3).

Tip: Replacing front brake discs on cars that
already have part number 4G0615301G installed
will not resolve the noise concern and will not be
covered under warranty.

Brake embedding:
1. Perform 10 stops from approximately 35 mph to 10 mph with medium pedal pressure.
2. Drive for approximately 2 minutes at approximately 40 mph without braking to allow the brakes to cool down.
