Footbrake - Lotus Evora 2011 Owner's Handbook Manual

Footbrake

Ventilated disc brakes are fitted to all four wheels of the Evora.
These are operated by separate front and rear hydraulic circuits,
supplied from a tandem master cylinder with vacuum servo as-
sistance. Anti-lock control is provided by a microprocessor based
electro-hydraulic unit, integrated into the base braking system.
The braking system is designed to provide good pedal feedback,
with efficient disc cooling to inhibit brake fade. With a new car, or
new brake system components, maximum braking efficiency will
be achieved if, for the first few hundred miles, needless heavy
braking is avoided. Allow the brake pads and discs to 'bed in' fully
before using the brakes to their full potential. Pedal effort will
reduce as the brakes are bedded in, and as they are warmed from
cold to normal working temperature. Note that the hard grade
pad material may give rise to a certain amount of brake noise
under some conditions; such noise is not harmful and does not
affect the life or efficiency of the brakes.
After frequent hard use of the brakes, it is beneficial to the
durability of the discs and pads if a cooling down period is allowed
before the car is parked.
WARNING
• After driving through a ford or flood, some loss of braking
response may be experienced until the brakes have dried
out. As soon as it is safe to do so after such an encounter,
apply the brakes until normal operation is restored. Failure
to do so may result in an accident in which you or others may
be killed or seriously injured.
• The brake assistance servo uses vacuum supplied from the
engine intake plenum, such that power assistance is avail
able only when the engine is running. Never coast downhill
with the engine stopped. If this situation should arise ac-
cidently, be aware that repeated application of the brakes
will rapidly exhaust the stored vacuum supply, after which
much greater pedal pressures will be required. This may
adversely affect brake performance which could result in an
accident in which you or others could be killed or seriously
injured.
