| Service Brakes problems |
The front passenger-side 6-piston brembo caliper's (part no. 20. A989. 63) external steel crossover tube failed due to corrosion, specifically where the tubing was covered by a protective rubber sleeve, which trapped moisture and road salt. This led to a catastrophic loss of brake fluid and braking capability. This appears to be a systemic corrosion defect.
