The 1990 Cadillac Limousine has 2 recalls, both addressing the same brake defect: undersized rear wheel cylinders that can cause dangerously extended stopping distances if the power brake assist fails.
When the power brake assist unit is not operating, the rear wheel cylinders are too small to generate adequate braking force, meaning the vehicle may not stop within the distances required by federal safety standards. This is most relevant in situations where the brake booster loses vacuum, such as when the engine stalls, leaving the driver with significantly reduced stopping ability.
At a glance
What can fail
The rear wheel brake cylinders are undersized, which prevents them from generating enough braking force to stop the vehicle properly.
What the fix does
Replace the original 1-inch rear wheel brake cylinders with larger 1 1/16-inch cylinders to restore proper braking.
