Mystery solved. If no fluid is visible, there may be a leak or the
brakes are extremely worn and require replacement. The seals in the
master cylinder may have also been damaged from the lack of fluid. Have
everything examined and serviced before she drives it again.

Something for you to ponder as a FAR more important issue than the
braking system on her Jeep: the need to regularly check vital fluids.

Take her aside for 10 mins, open the hood, and show her how to check all
important fluid levels, then have her do it while you're standing there
to be sure she knows how. This is a very important skill for young
ladies to have, and it is an important lesson that parents should teach
any aspiring driver.

Re: 'GC - Emergency Brake Light always on...
 

She really needs an automotive education.

When the Brake failure warning light comes on, the vehicle is no longer
safe for the road until it has been determined the failure.

When one reservoir goes empty, it puts serious stress on the seal
between the master cylinder chambers which can lead to a 'total' failure
there 'very' soon after one goes dry.

When this happens, the brake pedal goes to the floor and the vehicle has
only the emergency brake left.

Does she know how to stop a vehicle using only the emergency brake?
Does the emergency brake work?

There are other red lights that mean 'stop now' too. One is the oil
light another is the temperature light and the other is the alternator
light.

The oil and temp can mean engine failure if the vehicle is still driven.

I borrowed a niece's vehicle once and the oil light was on. 'oh is that
what that means' was her response as we figured there was only one
quart left in the now destroyed engine. It went to the scrap yard soon
after.

Re: 'GC - Emergency Brake Light always on...
 

Good points all.

We've owned this car since '94. It was OK when she was driving around
our small town (high school was a mile away). She is now 2 hours f/
home and uses this 13 year old car to commute and go on weekend trips.
I have not been comfortable with her driving the car for several
months.

I bought a '99 GC w/ 115k miles last week which we are picking up
tomorrow AM. Mechanically, it seems to be a much better car than the
'94 has been in a long time (if ever). The service and CarFax check
out.

I really appreciate all your input.

Only problem now is that when I pulled the plastic sensor out at the
master cylinder, I stripped the entire end off while reinstalling. So
the metal plunger and plastic thread are in the master cylinder, but
the nut and terminal have torn off. At least I have a few days to get
it out....

Re: 'GC - Emergency Brake Light always on...
 

My CJ5 turns the light on depending on the position of the ignition switch.
I have to physically roll the switch towards OFF (away from START) to turn
the Brake light off.

This light is also used to indicate a problem with the brake fluid level
and/or the brake system in general.
