Brakes - Aston Martin DB11 Owner's Handbook Manual

Brakes

Footbrake
The footbrake uses a vacuum boosted, dual (diagonal split) circuit
hydraulic system with Anti-lock Brake System (ABS).
Warning: In the event of a brake failure, bring the vehicle
to a stop as soon as it is safe to do so. Do not continue to
drive the vehicle. To do so could result in an accident or
collision resulting in death or serious injury.
Warning: Greater care may be necessary after a long drive
over salted or gritted roads or if driving in heavy rain,
through water or a vehicle wash. Brake action may be
delayed and increased braking pressure may be required.
Warning: Aston Martin recommend that the brake fluid is
replaced before and after the vehicle is used for high
performance driving such as a track day. Failure to do so
may result in greatly reduced brake performance. Contact
your Aston Martin Dealer.
If vacuum boost or a brake circuit fails, the footbrake will
still operate, but with greater pedal pressure, increased pedal
travel and longer stopping distances. Contact your Aston
Martin Dealer.
(V12 Engine Only)
Vacuum boost is only available with ignition at position II or while
the engine is running.
The high performance brake system used on this vehicle is
designed to provide optimal braking under all operating
conditions. However, an inherent characteristic of this braking
system is some brake noise. Certain combinations of speed,
braking forces and ambient conditions may also cause the brakes
to squeal.
Brake Throttle Override
If the throttle and brake pedals are both pressed at the same time
for over 3 seconds, the engine will restrict available torque.
Normal functionality will return when the throttle pedal is
pressed without the brake pedal.
