Brake System - Jeep GLADIATOR 2020 Owner's Manual

If frequent engine coolant (antifreeze) addi-

tions are required, the cooling system should
be pressure tested for leaks.
Maintain engine coolant (antifreeze) concen-

tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled
water for proper corrosion protection of your
engine which contains aluminum compo-
nents.
Make sure that the coolant expansion bottle

overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your

vehicle is equipped 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 coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.

In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the
"Maintenance Plan" located in "Scheduled
Servicing" in "Servicing And Maintenance" for
the proper maintenance intervals.
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.
SERVICING AND MAINTENANCE
Refer to "Fluids And Lubricants" in "Technical
Specifications" for further information.
WARNING!
Use only manufacturer's recommended

brake fluid. Refer to "Fluids And Lubri-
cants" in "Technical Specifications" for
further information. 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 reser-
voir.
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.
