    Brake lights sometimes stay on after car is turned off.
    Initially assumed that the problem might be related to switch, so tried jiggling brake pedal, also pressed pedal on/off many times, but all three brake lights stay on. Then, pulled ground battery cable, reattached, and this immediately resolves the issue. This has ...

      See this FIG : Indicators and Stop Lamp Switch(c) (2003).
      The stop lamp ABS switch is connected to the electronic brake control module ( EBCM ), that may be the problem.

      Unhook the negative connection to the battery and leave it off for 15 minutes. The reconnect it. You will need to fix the time and radio channels but normally the computer is reset.

    My speedometer quit working the same day i had my front rotors and disc brakes replaced. rightaway it started squeeking
    could it be my speedometer sensor bad or not adjusted right

      There is nothing at the front rotors that can cause the speedometer to fail. The only thing there is a wheel speed sensor for the abs brakes. There is no relationship between the speedometer and the front wheels. there is also no adjustment at all. if your brakes squeak some, give it a few days for the pads and rotors to break in and seat. The speedometer is controlled by the vehicle speed sensor located on the transmission and generally not even within easy reach.

    If i am pressing down, almost to the floor to stop, does that mean i need new brake pads? I have put in new brake fluid.
    It feels like something is scraping

      You should check the thinkness and it is possible that the scrapping sound is from your brake pad wear indicator.

      A broken brake booster may be the cause of the brake pedal get hard when pressed.


      POWER BOOSTERS
      Virtually all modern vehicles use a vacuum assisted power brake system to multiply the braking force and reduce pedal effort. Since vacuum is always available when the engine is operating, the system is simple and efficient. A vacuum diaphragm is located on the front of the master cylinder and assists the driver in applying the brakes, reducing both the effort and travel he must put into moving the brake pedal.
      The vacuum diaphragm housing is normally connected to the intake manifold by a vacuum hose. A check valve is placed at the point where the hose enters the diaphragm housing, so that during periods of low manifold vacuums brakes assist will not be lost.
      Depressing the brake pedal closes off the vacuum source and allows atmospheric pressure to enter on one side of the diaphragm. This causes the master cylinder pistons to move and apply the brakes. When the brake pedal is released, vacuum is applied to both sides of the diaphragm and springs return the diaphragm and master cylinder pistons to the released position.
      If the vacuum supply fails, the brake pedal rod will contact the end of the master cylinder actuator rod and the system will apply the brakes without any power assistance. The driver will notice that much higher pedal effort is needed to stop the car and that the pedal feels harder than usual.

    How long should it take a shop to change the rear brake lines?
    The brake light came on in the car and I went to change the brakes but they were not too low. I checked the brake fluid level which was low so I added some fluid. The brake light went out for a while but came back on later that day. I noticed a trail of fluid ...

      I agree with that estimate. Your bill will be about $300 to replace the rusted line or lines. Give or take $75

      If your rear window brake light works then I would suspect the wiring harness connector. You will need to pul back the carpeting on the inside fire wals to look at.

      CHECKED THE WIRING HARNESS CONNECTOR AND THAT WAS NOT THE PROBLEM. I WAS TOLD IT COULD BE THE TURN SIGNAL SWITCH. NOT UNDERSTANDING HOW THAT COULD BE THE PROBLEM WITH THE BRAKE LIGHTS NOT WORKING(TURN SIGNAL SWITCH). .

      Try grounding metal part (or bulb sockets) tail light assembly to a known grounded part of the frame with a jumper wire and see what that gives you.

    The ABS and Traction control lights come on once in awhile. What should I look for to repair?
    70,000 miles Happens when vehicle cold or wet; most often after backing up

      Have your vehicle put on an obd2 scanner that has the cabability to test abs as well. You'll probably find that a wheel sensor is your problem. If it shows a wheel sensor it will require a hub assembly replacement as the wheel speed sensor is integrated in the hub assembly.

      You have to diagnose your vehicle with a scan tool/code reader capable of reading ABS troublecode to determine what the stored troublecode is. The extracted troublecode will help you identify the fault of your warning lights.

      Bad master cylinder or you are not bleeding it correctly or there is a crushed steel line going to the rear brakes or both rear wheel bleeder screws are clogged.

    Not all of my brake lights work
    For some reason only the passengers side brake lights work on my car, not the left side or the cyclops in the middle. Does anyone know how to fix this? Thanks in adavnce for any information.

      Try this, press the brake pedal and check for battery voltage and ground at the brake light bulb socket. And if present, replace the bulb. If either battery voltage or ground is not present.

    Having trouble getting front brake caliper piston back into place. Have loosed the bleeder valve screw.
    Have applied prying force with screwdriver and pressure force with c-clamp type. Doesn't seem to be moving at all.

      Using a large C-clamp, bottom the piston in the caliper bore by positioning the C-clamp on the outboard pad and on the round portion of the brake caliper where the piston is housed.

      sounds like you need a new brake caliper to me unless its a screw type piston but I've only ran into those on the rear of a car once

      did you loosen the top of the master cylinder to allow the fluid to run back into the reservoir?

      A dirty or faulty ABS sensor can cause it. But you have to diagnose your vehicle with a scan tool/code reader capable of reading ABS troublecode to determine what the stored troublecode is.
