Jeep 2004 Wrangler - Manual (Page 244)

WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the BRAKE warning light shows system failure
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. 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. However,
low fluid level may be caused by a leak and a checkup
may be needed.
Use only manufacturer’s recommended brake fluid, refer
to Recommended Fluids, Lubricants, and Genuine Parts
for correct fluid type.
WARNING!
• Use of a brake fluid that may have a lower initial
boiling point or unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
