    How do I install the drivers side brake light assembly?

      Open the trunk of the Buick LeSabre.

      Locate 7 nuts underneath the trunk lid (3 on each end of the trunk lid and 1 in the middle). Remove each one using a nut driver.

      Manipulate the trunk lid at chest level and gently pull the rear taillight assembly slightly away from the trunk lid.

      Locate the burned out bulb sockets and then remove the bulbs. Insert the new bulbs into the socket and test by turning on the lights before reassembling.

      Replace the tail light assembly by aligning the studs inside the predrilled holes in the trunk lid. Refasten the 7 nuts.

      Remove the cargo net if applicable to replace the brake and/or turn signal light.

      Unscrew the plastic wingnut that the cargo net is attached to. Pull back the trunk liner.

      Remove the 2 plastic wingnuts under the trunk liner.

      Pull the brake light assembly outward from the back of the LeSabre.

      Locate the socket of the burned out bulb and then turn counter clockwise 1/4-inch to release it from the assembly.

      Remove the old bulb from the socket and replace with a new one. Test the light before reassembling.

      "I have noticed that it would seam that the pedal travel level is a bit lower but once the brakes are applied it would seam that the pedal is at full mast again could this be a vacume problem perhaps the assist booster ? " - I believe what you are doing is double pumping the brakes to activate, i can visualize it based on your description. ABS module is probably dead. Maybe air in line, but my guess is the earlier. Could be the brake booster, but doubt master break cylinder.

      Thanks I am thinking its not the ABS based on the fact the ABS light is out after startup diagnostics I am leaning towards the booster

      Are you saying that you want to "eliminate" the right rear brake line and the function of the right rear brake instead of repairing the leak? If that is what you are saying then you know I would never give that a thumbs up. If I am misunderstanding you please explain what you mean.

    I'm having problems with my front end (brakes) heating up on occasion, especially on steep grade of hill.
    Problem is intermintent. One side will be fine but other side will heat up then the other way around. Ive changed calipers ,pads, rear cylinders , bearings, booster , .master cylinder but it does what i said above overheats on steep grade of hill.

      if just front dude...check your rubber hoses or just replace..they will eventually clog up....if it doesn't solve your problem..proportioning valve.

      Proportional or combination valve was thought of but cant find part at auto parts houses.Hoses were change awhile back . I rebleed calipers with brake hand vacuum pump (cold brake fluid) and it did help. If you know of anyone who has proportiong valve I would like to update brake system jimmy

      1. Inspect the light bulb.
      2. Inspect the bulb socket, it could be rusted or contaminated and diminished the current flow to the bulb.

      Short answer = yes. The brakes can fail suddenly for a number of reasons; loss of brake fluid (leak in the brake system), loss of engine vacuum = loss of power brake boost, faulty brake master cylinder, leaking power brake booster (failed diaphragm) - to name a few possibilities.

      Does it make any sound? Check your brake fluid reservoir first and see if low.

      Try to have the vehicle raised to remove the wheel and inspect the brakes and wheel hub for any missing parts / bolts. Several possibilities; fastener not properly torqued or tightened, fastener not secured correctly with cotter pin - if equipped. Best advise is to take the vehicle to a trusted and reputable technician to inspect the condition and issue you are having. To locate a repair shop in your area - try the 'Find-A-Shop feature on this website.

      Get the engine scanned and post the codes here. The problem could be that the idle control valve is clogged of the TPS sensor or its circuit is defective.

    I installed new front brake pads and now they are rubbing
     
    • Jimm
      7/9/2011 Jimm
      The new front brake pads may have a slight drag - this is considered as normal. Not sure of your 'rubbing' description - is the rubbing observed between the brake and rotor? Recommend to check the caliper and piston to be sure the piston is fully retracted. Also, make sure the brake pad has the anti-squeal pad and lubricant applied to the metal backing plate where the pad contacts the piston.

      I have found on some late model GM applications that aftermarket brake pads (as opposed to the genuine original ACDELCO $140 pads) that many brands are noisy, at least initially after doing the job.

      Make sure that you did not bend the dust shield slightly while changing the pads and now the metal shield is slightly "rubbing" on the edge of the rotor.

      Only one way to solve this problem, while these blinking light might mean your wheel speed sensor or ABS might be faulty, a scan will be able to verify this. Its easy really...

      1. Get it scanned
      2. Post the code here in this forum
      3. Get your answer including ways on how to change a particular part.

      sounds like your brake light switch is stuck. look under dash at top of brake pedal and find the switch. it has a push pin(plunger) that may be stuck in. Pull it out and check your lights. they should be off now. spray it lightly with a lube like wd40 and work it a few times to loosen. should do the trick, if not replace the switch usually about $8 - $12.
