    Why does ABS seem to activate at very slow speed and almost at complete stop.when not on slippery surface?
    mileage 95,000. ABS activation is intermitant. No warning lights are on. Calipers replaced. Some rusted brake lines replaced.

      One of the front hub bearings is junk. There *might* be a stored abs code but if you can't read GM abs codes then that won't work as a direction. That leaves you with jacking up each front wheel and spinning and wiggling each and basically going with a hunch on whether the left or right hub bearing should be replaced. the wheel speed sensor is integral with the hub bearing and when the bearing gets play in it it causes false abs activation.

      Scan the engine for codes to be sure but a stuck caliper will not directly cause light. Your engine would have to work extra hard to move the vehicle with dragging brakes. You should check then erase code then fix brakes road test vehicle and recheck code if light returns. If you post the code I could help more.

      Generally speaking, no.

      If the rotors are scored or warped, they need to be replaced. If there is no "pulsing" they are probably not warped. If they are scored they will shorten the life of the new pads and reduce the braking ability of the vehicle.

    Left front brake pulls to left and overheats when the weather is hot! What causes this?

      Several possibilities; faulty / collapsed flexible brake hose at the caliper, dirty / contaminated brake fluid in the system, faulty / sticking left front brake caliper and piston.

      First of all, make sure the rear brakes are properly adjusted. The adjustment is made with a brake adjuster tool through backing plate. Driver side access below axle isn't too hard, but the pass side adjuster is above axle and the access is harder.
      Lift rear wheels off ground, spin wheels and tighten adjuster until resistance felt and heard, and back off slightly.
      To tighten driver side rear parking brake, turn star-wheel adjuster down.
      To tighten passenger side rear parking brake, turn star-wheel adjuster up.

      The only thing you can do other than getting new brake shoes would be to see if the cable has some slack in it. The place to do this is under the cab on the drivers side. the cable runs on the out side of the frame rails, there will be one cable coming from the left front wheel area. There is a bracket on the end of it with two more cables attached to it that go back to the wheels. If there is slack in the cables you can try and tighten the nut on the center cable.

    Why does only my front left wheel squeak when driving, gets louder while braking?
    Mileage is around 70,000. Pretty sure it only happens in warm weather, although with windows up and freezing temps in winter climate I can't hear it. I just started noticing it, while windows are down. No warning lights are on.

      Check the brake pads thickness. The noise could come from the brake wear indicator, it's touching the disc rotors.

      What thickness of pads am I looking for to know they should be replaced? I can't exactly see them but the space between caliper and rotor is roughly 1/8 inch to 1/4 inch.

      try beading your breaks, if they havent been serviced in a while, they could have water or air in them.

      Brake Light Switch
      REMOVAL & INSTALLATION


      Disconnect the negative battery cable.
      Disable the SIR system (if equipped).
      Remove the clip (R/V Series) or unclip the switch (C/K Series) and unplug the electrical connector from the brake light switch.
      Remove the switch.
      Installation is the reverse of removal.

      Or

      To replace a stoplight switch, first determine what type of switch you have.
      If you have an electrical switch mounted to the brake pedal in the passenger compartment:
      Unscrew the switch.
      Unplug the wires.
      Replace with a new switch. Adjust as needed.
      Plug the wires back in.
      If you have a hydraulic pressure switch that is mounted in the brake master cylinder:
      Mark and disconnect the wires.
      Unscrew the switch.
      Screw the replacement switch in.
      Reconnect the wires.

      Usually, the sudden grabbing is related to a sticking / faulty / seized brake caliper, or faulty / worn wheel bearing. Try the many on-line auto parts sources, such as; www.autopartswarehouse.com, www.partsgeek.com and www.rockauto.com for the replacement parts.

    When replacing front brake pads do brakes need to be bleeded after?
    N/a
     
    • CVO

      Replacing the front brake pads won't need to bleed the brakes because there is no air is leaked in the repair process.
