The hydraulic brake pressure reduction valve causes the rate of hydraulic pressure reduction to slow down, which may result in the rear wheel locking-up even with the anti-lock brake system in operation. Rear wheel lock-up may result in loss of vehicle control and an accident.

Porsche dealers will install a modified hydraulic brake pressure reduction
valve.
