I'll suggest just installed a new brake light switch and i got the switch from dealer. First adjust the switch so as soon as touch the brakes, the lights come on.

However realized that the gear lock light newer comes on because the brake pedal cannot pushes the switch enough to make it on. That is why transmission throws brake light switch error. Then readjusted switch that when the brakes released the gear lock is on and as soon as touch the brakes the gear lock goes off. So it is working OK.

However because of the adjustment, the the brake lights do no come on as soon as i touch the brakes. I am assuming that because of this it throws the error above because the sensor detects pressure even if the brake lights are not on.

P.S. Here is a guide from ross-tech's wiki.

2010 Dodge Grand Caravan break light stays on in dash.


Check the level of your brake fluid or your brake pads may be worn down and time to have them checked out.

1989 FORD F250 BRAKES LOCK UP WAIT 30 MINUTES BRAKES UNLOCK


There may be dirt in the lines or the calipers. When you press the pedal it forces fluid into all 4 brake calipers. If a line has dirt in it, it might get stuck in one of the orifices, causing them to stay in the locked position. Over time, the pressure in the caliper leaks back out and they release.
Have a mechanic do a brake fluid flush, preferable a "reverse" flush to push everything up and out through the brake fluid reservoir. Total cost should be about $30 for the fluid and 1 hour of shop time.

NO BRAKES


First check the brake fluid. If low, add to the full mark and check for leaks- fluid should never normally need adding. If the brake reservoir was dry, you will have to bleed all four brakes.
If the fluid is not low, then probably the brake master cylinder has gone bad. The internal seals can give out and won't make pressure.

How do I bleed brakes on a dodge stratus 1998


  • PRESSURE BLEEDING
  • MANUAL BLEEDING
  • Print
    For vehicles equipped with an Anti-lock Brake System (ABS), please refer to the ABS bleeding procedure at the end of this section.
    The purpose of bleeding the brakes is to expel air trapped in the hydraulic system. The system must be bled whenever the pedal feels spongy, indicating that compressible air has entered the system. It must also be bled whenever the system has been opened or repaired. If you are not using a pressure bleeder, you will need a helper for this job.

    WARNING Never reuse brake fluid which has been bled from the brake system.


    MASTER CYLINDER

    See Figure 1
    If the master cylinder is off the vehicle, it can be bench bled.

    1. Secure the master cylinder in a bench vise.
    2. Connect 2 short pieces of brake line to the outlet fittings, bend them until the free end is below the fluid level in the master cylinder reservoirs.
    3. Fill the reservoir with fresh DOT 3 type brake fluid.
    4. Using a wooden dowel, or equivalent, pump the piston slowly several times until no more air bubbles appear in the reservoirs.



    0900c15280089cdc.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. Fig. 1: Attach bleeding tubes to the master cylinder and position them as shown

    1. Disconnect the 2 short lines, refill the master cylinder and securely install the cylinder cap.
    2. If the master cylinder is on the vehicle, it can still be bled, using a flare nut wrench.
    3. Open the brake lines slightly with the flare nut wrench, while pressure is applied to the brake pedal by a helper inside the vehicle.
    4. Be sure to tighten the line before the brake pedal is released.
    5. Repeat the process with both lines until no air bubbles come out.
    6. Bleed the complete brake system, if necessary.

    If the master cylinder has been thoroughly bled and filled to the proper level upon installation into the vehicle, it is not necessary to bleed the entire hydraulic system.


    PRESSURE BLEEDING

    When bleeding the brakes, air may be trapped in the brake lines or valves far upstream, as much as 10 feet from the bleeder screw. Therefore, it is very important to have a fast flow of a large volume of brake fluid when bleeding the brakes, to make sure all of the air is expelled from the system.
    On Cirrus, Stratus, Sebring convertible and Breeze models, the following wheel sequence should be used to ensure that all the air is removed from the system:


    Left rear wheel Right front wheel Right rear wheel Left front wheel
    On Sebring coupe and Avenger models, the following wheel sequence should be used to ensure that all the air is removed from the system:


    Right rear wheel Left front wheel Left rear wheel Right front wheel

    1. You should use bleeder tank tool C-3496-B or equivalent, with the required adapter for the master cylinder reservoir to pressurize the hydraulic system for bleeding. Make sure to follow the manufacturer's directions for using a pressure bleeder.
    2. Attach a clear plastic hose to the bleeder screw located at the right rear wheel, then place the hose into a clean jar that has enough fresh brake fluid to submerge the end of the hose.
    3. Open the bleeder screw at least one full turn or more to get a steady stream of fluid.
    4. After about 4-8 oz. of fluid has been bled through the brake system and an air-free flow is maintained in the hose and jar, close the bleeder screw.
    5. Repeat the procedure at all the other remaining bleeder screws. Then, check the pedal for travel. If pedal travel is excessive or has not improved, enough fluid has not passed through the system to expel all of the trapped air. Be sure to monitor the fluid level in the pressure bleeder. It must stay at the proper level so air will not be allowed to re-enter the brake system through the master cylinder reservoir.
    6. Once the bleeding procedure is complete, remove the pressure bleeding equipment from the master cylinder.


    MANUAL BLEEDING

    See Figure 2
    Proper manual bleeding of the hydraulic brake system will require the use of an assistant.
    On Cirrus, Stratus, Sebring convertible and Breeze models, the following wheel sequence should be used to ensure that all the air is removed from the system:


    Left rear wheel Right front wheel Right rear wheel Left front wheel
    On Sebring coupe and Avenger models, the following wheel sequence should be used to ensure that all the air is removed from the system:


    Right rear wheel Left front wheel Left rear wheel Right front wheel

    Fig. Fig. 2: With a clear plastic hose in a container of clean brake fluid, open the bleeder screw at least one full turn

    1. Attach a clear plastic hose to the bleeder screw located at the right rear wheel, then place the hose into a clean jar that has enough fresh brake fluid to submerge the end of the hose.
    2. Have an assistant pump the brake pedal 3-4 times, and hold it down before the bleeder screw is opened.
    3. Open the bleeder screw at least one full turn. When the bleeder screw opens, the brake pedal will drop.
    4. Close the bleeder screw. Release the brake pedal only AFTER the bleeder screw is closed.
    5. Repeat the procedure 4 or 5 times at each bleeder screw, then check the pedal for travel. If the pedal travel is not excessive, or has not been improved, enough fluid has not passed through the system to expel all of the trapped air. Make sure to watch the fluid level in the master cylinder reservoir. It must stay at the proper level so air will not re-enter the brake system.
    6. Test drive the vehicle to be sure the brakes are operating correctly and that the pedal is solid.

    Just the other day my brake pedal starting going almost to the floor before the brakes activated... checked brake fluids and its full but i boticed that if the car wasn't on that the brake pedal acted...


    Given the age of your vehicle and that you do not see any fluid loss, the most likely reason for the brake peddle act this way is because of an internal leak in the master cylinder.
    The master cylinder has a piston the operates the brakes when pressure is applied from the peddle. Basically, this piston provides and maintains the fluid pressure because of rubber "O" rings or seals. If the seals are going bad (due to age and wear) the fluid will bypass the piston but still stay in the cylinder and reservoir.
    The master cylinder can be rebuilt or new one cost $65-$120 depending on if you have anti-lock brakes. Here is a link to a supplier (with part photos) (Click Here) Labor about 2-3 hours.

    The "BRAKE" light on the


    I would check the brake fluid level. It is under the hood on the drivers side up near the windshield. There will be a white/clear reservoir with a black cap(Might mention DOT3 only on it). Open that up and check the fluid level, it should be at least 1/2 full to full. (there is marks on the reservoir that show what full is).

    Red brake light flashing periodically - ??


    Often this is because the brake fluid level is low. There is a sensor in the brake fluid reservoir that turns on the dash warning light when it does not sense enough fluid. You can visually check the brake fluid reservoir by looking at the reservoir under the hood. There are marks on the reservoir to show the correct level. If the fluid is low, this means that one of your brake system components is leaking fluid and needs to be replaced or repaired. If the fluid level is ok, possibly there could be air bubbles in the system, and it needs to be bled. If bleeding does not solve the problem, it could mean that the master cylinder is not holding pressure. If the brake pedal is spongy but it becomes firm after a few pumps, usually this means air in the system. If it stays spongy after pumping, and sinks continually when you press it, probably the master cylinder needs to be checked.

    It means you have to add fluid to the reservoir If you don't, you will get air into your brake lines and your brakes will fail.
