Braking and Stopping
CAUTION: In the unlikely event that Model X loses
electrical power, you cannot access the
touchscreen and are therefore unable to release
the parking brake. Contact Tesla.
Brake Wear
Model X brake pads are equipped with wear indicators.
A wear indicator is a thin metal strip attached to the
brake pad that squeals as it rubs against the rotor when
the pad wears down. This squealing sound indicates
that the brake pads have reached the end of their
service life and require replacement. To replace the
brake pads, contact Tesla Service.
Brakes must be periodically inspected visually by
removing the tire and wheel. For detailed specifications
and service limits for rotors and brake pads, see
Subsystems on page 199. Additionally, Tesla
recommends cleaning and lubricating the brake calipers
every year or 12,500 miles (20,000 km) if in an area
where roads are salted during winter months.
WARNING: Neglecting to replace worn brake
pads damages the braking system and can result
in a braking hazard.
