    Why am I having a problem with brake lights?
    When the lights are on both tail lights function properly. When I apply the brakes one goes out and the other does not brighten. When lights are off one brake light works. The third brake light functions properly all the time.

      Are you saying, when the lites are off, the brake lites work properly? If so, check the ground circuits at the lower rear. Otherwise, I'd have to use wiring diagram to check voltage and ground circuit for lower brake lamps.

    Why won't the brake lights and warnings go off?
    The service elec brake system and traction control light came on. The outside brake lights won't turn off either. The diagnostic computer said the brake switch was stuck. Replaced it still has same problem. Brake lights stay on with the switch removed.

      It is vital to check and adjust the push rod on the booster before mounting the new master. If it is too far out, it will apply the brakes but will not retract enough to release them.

      i dont think the brakes are being applied at all because when i press the pedal it is hard and at the top but the tires can still be spun also i am not getting any fluid at the master cylinder when pumping the brakes and cracking the lines at the master

      try this build brake pressure open the line at the master cylinder if fluid flows out and caliper release then everything from the open line to the caliper is open and working fine. then open at the proportion valve line.

      I have already tried both suggestions and I have gotten flow at both locations. The only thing I haven't changed is the proportal valve. Would you have done that as well. Next question is is there an adjustment to the valve or just replace it?

    There is a leak on the driver side near the rear door. The brakes are going to the floor when pressed. What is this?
    The fluid leak appears to be brake fluid. It is leaking out of a channel that runs under the Jeep to the back end.

    Long brake pedal travel after brake lines were replaced.
    It has about 125,000 miles. I had the rear caliper hose replaced because it was locking up the caliper. A few days later I also had the main metal line replaced for the rear brakes. Ever since the lines were replaced it feels like the brake pedal travels very far ...

    How do I replace the valve stem for my tire?
    I realized the front tire had no air so I tried to fill the air but the valve is broken. Any suggestions or advice ?

      Place the spare on the front tire, take the front tire with the faulty valve stem to a local tire store for a replacement valve stem - should cost no more than a few dollars.

    Odor and heat from left rear wheel.
    255,000 miles. After driving highway speeds for an hour or so, I detected an odor similar to hot rubber or electrical. I tracked it to the left rear wheel/tire. Strong odor in wheel well and the wheel itself was very warm to the touch. My mechanic suspected a ...

      Use an infrared thermometer to read actual temperature of the suspected problem wheel and compare it to the right rear temperature. You can get one of these cheap from harbor freight for like $15 . You may be right but if your mechanic did not see any evidence of something wrong upon inspection of said problem wheel, then maybe the cause lies elsewhere, like maybe a plastic trash bag that has been caught on and then melted in place on a hot component of the exhaust system. Seen this many times and there is always a delay in smelling it because it takes time to heat up and begin to give off the odor.

      check your axle shaft and the u-joint it could cause the same problem. and your brakes could be locking i would check the brake lines may need to be bled.
