It could quite possibly be the gears and bearings in your differential are wearing and it is loose. You will only notice this when you come to a complete stop because the vehicle rocks back and forth and makes that nasty clunking noise that makes you believe it is your brakes or a loose/worn wheel hub assembly. Have someone go a few inches forward and slam on the brakes in your driveway while you look under the truck at the diff. See if it is sloppy when the vehicle is stopping. Do it in reverse as well. My brother in law's truck (a Tahoe) does that and he thought it was the braking system as well.

Where's is the fuse located for my brake lights on my 2007 Pontiac g6 and rear defrost fuse


Stop Lamps
your br
The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The brake pedal position sensor provides an analog voltage signal that will increase as the brake pedal is applied. The body control module (BCM) provides a low reference signal and a 5-volt reference voltage to the brake pedal position sensor. When the variable signal reaches a voltage threshold indicating the brakes have been applied, the BCM will apply battery positive voltage to the stop lamps, transmission control module (TCM), engine control module (ECM), and stop lamp relay coil side. When the stop lamp relay receives battery voltage from the BCM, the relay coil is energized and the stop lamp relay switch contacts close applying battery voltage through the STOP LP fuse to illuminate the center high mounted stop lamp (CHMSL).
I'd say you have more then a bad fuse ,just reading how the brake lights function .You should have it hooked up to a professional grade scan tool ,one that can check for DTC'S - diagnostic trouble codes in the BCM - body control module !
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, observe the Brake Pedal Position Sensor parameter in the data list for the body control module (BCM).
  4. Apply and release the brake pedal.
Does the scan tool display a change in the voltage?

  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
Does the scan tool display DTC C0278 00?
Go to Step 3
Go to Testing for Intermittent Conditions and Poor Connections

Recalibrate the brake position sensor.

Circuit Description
DTC C0870
The body control module (BCM) applies a ground through the brake sensor reference low circuit to the brake pedal position (BPP) sensor. The BCM supplies a 5-volt reference through the brake sensor reference voltage circuit to the brake position sensor. When the brake pedal is being applied, the BPP sensor then sends a variable voltage signal through the brake sensor signal circuit to the BCM.
Circuit/System Verification
  1. Ignition ON, observe the scan tool Brake Lamp Cmd. parameter as you apply and unapply the brake pedal. The parameter should change between OFF and ON as the brake pedal is applied and released.
  2. ?‡'
    If the parameter does not change as the brake pedal is applied and released, refer to Brake Pedal Position Sensor (BPPS) Malfunction.

  3. With a scan tool, command the LR Stop/Turn Signal Lamp ON and OFF. The LR turn signal should turn ON and OFF when changing between the commanded states.
  4. ?‡'
    If the LR stop lamp does not illuminate when commanded, refer to Stop Lamps Malfunction.

  5. With a scan tool, command the RR Stop/Turn Signal Lamp ON and OFF. The RR turn signal should turn ON and OFF when changing between the commanded states.
?‡'
If the RR stop lamp does not illuminate when commanded, refer to Stop Lamps Malfunction.

How to adjust parking brake on 1993 chevy lumina ?




  • Adjustments




  1. Apply service brake pedal three times with a force of approximately 175 lbs.


  2. Fully apply and release parking brake three times. Full application may require two pedal strokes.


  3. Raise and support vehicle, then mark relationship between wheel and axle flange.


  4. Check parking brake pedal assembly for full release as follows:






    1. Turn ignition switch to On position.


    2. If ``Brake\'\' lamp is illuminated, operate manual brake release and pull downward on front parking brake cable to remove slack from pedal assembly.





  1. Remove rear wheel and tire assemblies, then install two lug nuts to retain each rotor assembly.


  2. If two parking brake levers on both calipers are not against lever stops on caliper housings, check for binding in rear cables and/or loosen cables at adjuster until both left and right levers are against their stops.


  3. Tighten parking brake cable at adjuster until either the left or right lever begins to move off the stop, then loosen adjustment until lever moves back barely touching stop.


  4. Operate parking brake several times to check adjustments. A firm pedal feel should be obtained by pumping pedal two full strokes and rear wheels should not rotate forward when parking brake is fully applied.


  5. Install wheel and tire assemblies, aligning marks made in step 3.

Ford Expedition 2001, #rd Brake lamp is not working please help.


At the central junction block, find 20A fuse 13 and check it. This fuse supplies power to the brake pedal position switch and switch output is applied to the three high mount stop lamps. If the regular stop lamps work when the brake pedal is pressed, the switch is OK. All three high mount stop lamps may have burned out

When coming to a stop, the brakes work fine until I get almost stopped, then the pedal will push down further and brakes will come on hard, and stop vehicle hard, what could be the problem?


Sounds like your master cylinder is bad on your brake system. If you are stopped in your driveway(not on the street) leave the vehicle in park. Start the car and place your foot on the brake with light pressure and keep this pressure on the pedal. If the pedal continues to drop slowly to the floorboard your master cylinder is leaking past the primary piston in the master cylinder. If this is the case have this repaired immediately. Your brakes could just all of a sudden not be there the next time you apply them when you need to stop.

How do I adjust the parking brake


Under the car on the drivers side you will see a threaded rod that goes through a saddle that goes off with two cables to the rear wheels, adjust the cable there using the adjustment nut.

1994 mazda cronos 2.00 v6 auto car idles ok drives ok but when i come to a stop it stalls in gear been atuo


This sounds like a problem with the torque converter lockup system. Usually the torque converter lockup solenoid is at fault in your condition. This solenoid usually locks up the torque convertor (which acts like a clutch in an automatic transmission) when you are driving at a certain speed, and unlocks it when you press the brake, and/or come to a stop. When a torque converter stays locked up, and you stop the vehicle, it acts like a vehicle with a manual transmission, if you bring the vehicle to a complete stop without applying the clutch pedal, the brakes stall the engine. Basically, if the torque converter can't unlock, even when you come to a stop, the engine is still locked to the transmission, and even when you apply the brakes, the torque converter doesn't slip and freewheel like it should, but instead stalls the engine.

2008 rav-4 toyota brake pedal continues to go down after you stop while holding the brake pedal at a red light.


If you own a Toyota with (BA) Brake Assist, it may be out of adjustment. It is adjustable on the 2010 Highlander and I would guess that it might be adjustable on your Toyota vehicle as well. (Assuming this is actually your problem, you have had it checked out by your service department and they said there is nothing wrong or that it was normal.) If the brake assist is out of adjustment it may be coming on too soon or when minimal brake pressure is applied. This causes a long brake pedal (brake fade or the pedal travels longer than normal before resistance is felt) and/or jerky brakes. As far as the Hill Climb Assist or DSC, this feature is activated when the brakes are applied after the vehicle has come to a stop and then you continue to press harder on the brakes for a couple more seconds. It also comes on if you drive with two feet. If you have your foot on the brake and you press slightly on the accelerator (when the vehicle is completely stopped), the DSC will come on and you will hear the chirp.
