Brake System - Jeep Gladiator 2021 Owner's Manual

Keep the front of the radiator clean. With air

conditioning, keep the front of the condenser
clean.
Do not change the thermostat for Summer or

Winter operation. If replacement is ever
necessary, install ONLY the correct type ther-
mostat. Other designs may result in unsatis-
factory engine system performance, poor gas
mileage, and increased emissions.

In order to ensure brake system performance,
all brake system components should be
inspected periodically. For the proper
maintenance intervals Ú page 384.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked whenever the vehicle is serviced, or
immediately if the brake system warning light is
on. If necessary, add fluid to bring level within
the designated marks on the side of the
reservoir of the brake master cylinder. Be sure
to clean the top of the master cylinder area
before removing cap. With disc brakes, fluid
level can be expected to fall as the brake pads
wear. Brake fluid level should be checked when
pads are replaced. If the brake fluid is
abnormally low, check the system for leaks.
For further information Ú page 462.
WARNING!
Use only FCA recommended brake fluid

Ú page 462. Using the wrong type of brake
fluid can severely damage your brake system
and/or impair its performance. The proper
type of brake fluid for your vehicle is also
identified on the original factory installed
hydraulic master cylinder reservoir.
SERVICING AND MAINTENANCE
WARNING! (Continued)
To avoid contamination from foreign matter

or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser-
voir cap secured at all times. Brake fluid in
a open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can

result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to

contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
