Brake Test
Brake tests can only be carried out on roller-type test stands or plate test stands.
The ignition must be switched off on the 911 Turbo! This is necessary because of the controlled four-wheel drive function - Porsche Traction Management (PTM).
If no four-wheel drive test stand (roller-type test stand) is available, the following limit values must not be exceeded for conventional roller-type test stands:
- Test speed: max. 8.0 km/h.
- Test duration: max. 20 seconds.
