    Brake lights not activating when brake pedal is applied.
    I own a 95 Supercharged Riviera and my brake lights are not being activated when appling the brake pedal. The light in the rear windshield does work. I have checked the fuse beneath the rear seat and its okay....

      check the brake light switch which under the dash just above the brake pedal arm, it has two wires on it might need adjustment or replacement , use a meter.

      Use this as a reference to access in the wiring diagrams 1995\GC\GCWR95RIVI011c

      Check the turn hazard switch assembly, it connected to the "Tail- Stop-Turn Lamp".
      The stop lamp brake switch is connected directly to Center High Mounted Stop Lamp, so it was using different circuitry and it's still functional.

      Thanks to all that provided infromation toward resolving my problem...It turned out that the problem was the
      turn signal switch . Located one in the savage yard $14.00 vs. a new one $378.00-$450.00.

      You have a faulty turn signal switch in the column. The brake light in the rear window has a separate wired circuit that bypasses the TSS. That detail is the smoking gun here. The brake light switch is working just fine otherwise the light in the rear window would also be out like the rear brake lights. Replace the TSS and use ACDELCO brand only or you may wish you did. Do not shop this particular part by price. Probability here is 99.9999%
  • TMAC
    TMAC - 1998 Buick LeSabre - Brakes - 7/19/2012
    What's length of brake lines will I need for my 98 Buick LeSabre?
    I don't have a double flaring kit so exact measurements would be best so I have to use the least amount of compression fittings.
     
    • Jimm

      You'll need to apply the double-flare at the fitting for sake of safety. Try the local auto parts store for the flare kit or tool. Try thes auto parts sources for the rigid brake line - best to purchase in bulk lengths - such as 25'.
      http://www.jcwhitney.com/.../buick-lesabre-1998, www.rockauto.com - to name just two sources.

      You cannot use compression fittings. Completely illegal to repair brake lines with compression fittings. Requires double flares. There is no database that tells the length of brake lines. You have to remove the old one or cut the old one at the point where it is still usable and fabricate new lines from a 25 foot roll.

      There's a good chance it's a wheel speed sensor, but you should check the ABS trouble code.

    AWD ENABLE LIGHT COMES ON ALSO THE ANTI LOCK LIGHT
    2002 Buick Rendezvous It has over a 120000. miles.-The AWD ENABLE LIGHT COMES ON ALSO AT THE SAME TIME THE ANTI LOCK LIGHT COMES ON. This happens sometimes when your just driving. Sometimes when your turning and braking, or backing and turning the wheel. Just once ...

      I have been having the same problem with mine for over two years now... Recently I was told that the Rotors need replacing and spee dee oil said they were going to put it on a lift to see more but could not that day... It was intermitten at first now the AWD lights come on every time and it's a blessing cause I don't get the growling noise when they're on...feels like it don't want to stop when it does that... scary they can't find the problem for almost 2 yrs now for me...If it is the front rotors that is and wheel barring on drivers side...I'm just dealing with it for now as I have been bc I can't afford to fix it! If you have a spee dee oil have them put it on a lift to check your rotors Good Luck

    Replaced leaking wheel cylinder bled brakes and still no brakes. Could it be master cylinder or power brake booster?

      Either you have a rusted through brake line which you would see dripping when pumping pedal or you are bleeding the brakes wrong. Your description of feeling like you have brakes with the car off - Do not let this confuse you, this is normal when the brake booster is not assisting with the pedal effort. the brake booster absolutely cannot cause this condition you have so do not replace it. Could be a master but my gut says no. Bleed all 4 wheels until each one emits a nice steady stream like a water fountain. I assume that you have the rear brake adjustment close.

    Justin H - 2002 Buick Century - Brakes - 6/14/2012
    I pressed hard on brakes and heard a hissing sound. now the brake peddle goes all the way in but doesn't work. Help me!
    I was able to get home but it took some time because i had to push the brakes in all the way to slow down to a stop. The brake light on the dash board is on. please help me figure this out before I spend a lot of money for someone else to figure it out. Thanks

      First check the fluid level at the master cylinder.
      If brake pedal goes all the way down most likely u lost the brake fluid due to a leak.
      Check the brake lines from the master cylinder for leaks.
      Check at each wheel the brake lines and the flexible hoses to the calipers,if something leaks should be wet.
      Check under the car for leaks in the brake lines.
      If all that looks ok the leak may be from the master cylinder,brake fluid leaks past the master cylinder seals into the brake booster.
      Hissing sound upon pedal application may be caused by a faulty brake booster diaphragm.

      Did you replace the front brakes? The front brake rotors need to be machined or replaced.

    Why does my car jerk, sputter, and sometimes go dead when i apply the brakes, but run ok the rest of the time?
    car has 196000 miles on it. runs ok up until i apply the brakes, then will jerk, sputter, and sometimes go dead. it will crank right back up after it does this. does not do it ALL the time, just sometimes. car runs ok except for this.

      Need more information - are you refering to the brake caliper bracket bolts? If yes, then the torque specification is; 129 ft / lbs. The brake guide pin bolts are; 64 nM or 30 ft / lbs torque.

      You should 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 your identify the fault of your warning lights.

      turns out it was loose wires on a speed sensor in the ABS/antilock brake system. Cost $18.50 labor to fix after the diagnose code fee.All the lights went off - yea!

    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.
