What NHTSA recorded
The hydraulic brake pressure reduction valve causes the rate of hydraulic pressure reduction to slow down, which may result in the rear wheels locking-up even with the anti-lock brake system in operation.
Possible consequence
Rear wheel lock-up may result in loss of vehiclecontrol and an accident.
Remedy
Porsche dealers will install a modified hydraulic brake pressure reduction valve.
