Brakes
Footbrake
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.
Warning: Track day use and high speed driving: For track
use or high speed driving new brake pads must be subject to
specific conditioning. Failure to correctly condition the pads
may result in greatly reduced brake performance.
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.
The brakes in this vehicle are not servo assisted, and may have
a different brake feel when first driven.
The footbrake uses a dual (diagonal split) circuit hydraulic system
with Anti-lock Brake System (ABS).
The carbon ceramic brake systems combine low weight with high
performance, offering:
• Reduced unsprung weight (mass of components not
supported by the suspension) to improve vehicle handling,
• Improved rate of wear characteristics,
• Improved braking performance.
The rate of wear of the brake pads and discs will depend on
driving style and usage conditions. Track day usage will increase
the rate of wear of discs and pads.
Brake Throttle Override
If the throttle and brake pedals are both pressed at the same time,
the engine will restrict available torque. Normal functionality will
return when the throttle pedal is pressed without the brake pedal
or the brake pedal is released.
