    Rear brake sticking.
    I have been experiencing that the rear passenger side brakes smell warm/hot. Has anyone else experienced sticking brakes and if so any remedies?

      Check the hose brake from the rear passenger side, it must have plugged with residue and hold the return pressure back to the brake lines.

    Having brake problems,
    I have a brake problem on a 1996 Buick Century Custom with ABS anti-lock brakes. Engine 3.1 Liter V6. (New pads) Right front brake pads wear out in about two months down to metal to metal. The other side is still like new. Replaced with new brake rotor, new ...

      Several possibilities; sticking brake caliper piston (replace the caliper), contaminated brake fluid (change / flush the brake fluid) in the system which causes the sticking brake caliper piston, collapsed front flexible brake hose (replace the hose).
      Check the many on-line auto parts sources, such as; www.autopartswarehouse.com, wwwpartsgeek.com, www.autoanything.com and www.rockauto.com - to list only a few sources. For example, they (Rock Auto) list the front brake caliper from around $12.50, and the front disc brake pads from around $8.20 (per axle set) for your vehicle.

      Realize that brake fluid is hygroscopic - meaning that the fluid is designed to absorb / suspend moisture. In the mositure is contamination from; the air, and particles from the brake system components, and dirt. Over time and mileage accumulated, and if the brake fluid becomes contaminated to the point it cannot absorb more impurities, then these impurities are deposited in the brake system; inside the brake calipers (disc brakes), wheel cylinders (drum brakes), and the flexible brake hoses - to name only a few areas.

      The build up of the dirt will then cause the caliper pistons to bind, the wheel cylinder pistons to stick - and the brake wear is accelerated as the brake pads and / or shoes cannot fully retract. This is the condition you have experienced.
      Going forward, keep the system maintained and clean with regular brake fluid changes, and start with new / remanufactured brake calipers for safety sake.

    We have replaced the brake pads on the right front twice. They only last a few short months and wear.
    They begin to grind and ruin the rotor Auto Zone will no longer warranty them because they feel something else is causing the problem. Any suggestions?

      Rotor, caliper, and brake pads have been replaced on the right side. They only last 2 months and are metal to metal. The left side was replaced over a year ago and is still like new. Brake fluid and hose have been checked. Any other suggestions?

      Do not assume that the side that is going metal to metal is the side with the problem. Most times the side that shows less wear is the side with the bad caliper or bad hose. Moral of this advice is make sure both calipers and both hoses are replaced and not "checked".
    • Jimm

      House Call Auto is correct - replace the brake calipers as well as the brake fluid in the system.

      Realize that brake fluid is hygroscopic - meaning that the fluid is designed to absorb / suspend moisture. In the mositure is contamination from; the air, and particles from the brake system components, and dirt. Over time and mileage accumulated, and if the brake fluid becomes contaminated to the point it cannot absorb more impurities, then these impurities are deposited in the brake system; inside the brake calipers (disc brakes), wheel cylinders (drum brakes), and the flexible brake hoses - to name only a few areas.

      The build up of the dirt will then cause the caliper pistons to bind, the wheel cylinder pistons to stick - and the brake wear is accelerated as the brake pads and / or shoes cannot fully retract. This is the condition you have experienced.

      In the future, keep the system maintained and clean with regular brake fluid changes, and start with new / remanufactured brake calipers for safety sake - of you and your passengers.

    We replaced brake drums on right front. They wear in a few short months.
    They grind and ruin the rotor. Auto Zone will not longer warranty them because they think something else is causing the problem. Any suggestions?

      If the right front brake pads are wearing out that fast you likely have a caliper not releasing. This can be caused by a bad brake hose or bad caliper. If you open the bleeder screw when you push back the piston it should go in easy if it binds replace caliper. You should start by inspecting all 4 brakes for proper condition and operation. Jack up each wheel tire should spin freely then apply brakes and make sure tire does not turn then release brake and see if spins free again. That should show which brakes work and if the calipers are releasing. Non-functioning rear brakes can cause the fronts to wear out fast. Check all 4 brakes for cracked hoses leaks premature or uneven pad wear and condition of rotors. You most likely need a new caliper. Calipers should always be replaced in pairs. I would recommend 2 front loaded calipers 2 rotors replace any bad hoses or lines and bleed all 4 brakes. If you change brakes only on one side you may cause uneven wear and brake pull.

      The caliper is new and the rotor.

      Is the brake dragging or wheel heating up while driving. Does vehicle pull right or left when brakes applied. If its not dragging and getting hot then you should check operation of the other three brakes. The side wearing out may be the only one operating correctly. If you bleed all four they should have the same pressure fluid stream out of each bleeder. You may have no pressure going to left front and right rear.

    Do I have a brake problem or a motor mount problem
    Car vibrates wildly when applying brakes when going downhill. Gets worse as car warms up.

      Does the brake pedal pulsate really bad when braking?If so,it means you need to get front rotors turned or replaced if they cant be turned.Put new pads on too so you wont put grooves in the new rotors.Brakes always get worse,the warmer they get or the more they're used in rapid succession.Broken motor mounts will normally make clunking or banging noises when accelerating and deaccelerating or when putting car in gear.

    What is the best pads, metallic or ceramic
    Should rotors be different for different pad material?
     
    • Jimm
      7/30/2013 Jimm
      The 'best' brake pads are the ones formulated for and equipped with your vehicle from the factory. For example, for the front disc pads, for the 2004 Buick Century with the 3.1L engine - the brake pads should be; semi-metallic.
      Stick with the proven and known name brands for all brake parts; Akebono, Bendix, Wagner, Raybestos, Beck-Arnley, AC Delco, Monroe - these manufacturers also supply direct to the vehicle manufacturers as original equipment (OEM) suppliers.

      Is it loosing any brake fluid (master)? Any kind of leak could cause a soft pedal. Also, the pads may not have been adjusted corrected when replacing.
    • John's Auto Repair
      Master cylinder could be leaking internally. Which pads did you replace, front or rear? If no leaks are
      found try replacing master cylinder and bench bleed it before installing

    Brake light on suddenly. no prior warning of any brake problems (pads and rotors 8/2012). pedal goes to floor.
    i don't think this could be pads or rotor since both replaced not long ago. no grinding, just pulls to left and barely stops. was fine one minute and barely stopping the next. wondering what else this could be. checked fluid, seems to be ok.

      A bad brake master cylinder. The master cylinder is where brake fluid gets compressed. Pressure on the brake fluid cases the brakes to be applied to the wheels. If your master cylinder doesn't work properly, or only works sometimes, you're going to lose braking power, and occasionally your brake pedal will go all the way to the floor.

      A bad brake booster. The booster is a mechanism that uses vacuum pressure to take the force being applied to the brake pedal and amplify it. If the booster is bad, then the full amount of force needed to activate the master cylinder and pressurize the brake fluid isn't going to be there. The pedal will go all the way to the floor and the car will be harder to stop.

      thanks for the info. don't know which i should wish for. they both sound like very expensive problems to fix.

      Have an assistant to pump the brake pedal while you're looking in the brake reservoir. If there is a jet of brake fluid flows back to the surface instead it's going to the brake lines to stop the car, then the master cylinder ( primary and secondary ) seals are broken. Use safety glass.

      If it is a bad brake booster, then there is no air escaped through the air intake vacuum hose when the brake pedal is applied ( the air intake vacuum hose to the brake booster has to remove prior to do the test)

      when i pump the brake pedal i hear what sounds like air coming out. i have no ability to mess with any parts - would probably make it worse. i'm just wondering if the "air sound" indicates hose mentioned above
      CVO
      5/12/2013 CVO
      If there is an air escaped sound, either that vacuum hose is broken or loose.

      No mystery, you need new brake pads. Look at the pads again. There s nothing else that would cause that symptom.

      one of the tunnels from your side or passenger side would be engorged and it prevents the air passing.. that gives the air blowing from this side to another exits .right now that you can do just check it if is okey (you can poke with a cable or wire. the problems come out cause of the ac's distiribitor.make a visit an expert. there is nothing doing from you.. have a nice day..

      Cool on the driver side and hot on the pass side is almost always caused by a faulty pass side blend door actuator. If it were the reverse (cool on pass side and hot on driver side the cause is always that the system is low on refrigerant.). Hope this helps.

      This is caused by a low refrigerant charge.

    Why does my brak pedal go to the floor after replacing front pads?
    I thought it might be the master cylinder so i replaced it also and bench bled it and then the lines and still no pedal and barely any brakes
     
    • Jimm

      Check the brake bleeding procedure; start with the wheel furthest from the master cylinder - usually the left rear, then right rear - and so on. Be sure to use clean, fresh brake fluid.

      From your description, the lack of pedal pressure would indicate there is still residual air in the brake system at some point.
