    Auto Doc estimates
    I see your estimates for auto shop work. Why are they way more $$$ when i go to the shops. Where are the savings @

      Keep in mind these are only estimates with no guaranteed savings - and they will have variance, just like if you went to any two or more repair shops in your location for the same work on the same vehicle. Each repair shop is free to charge labor repair rates based on the market conditions and competition - among other factors in order to make a profit and stay in business.

      Check the connector on the LF wheel. It may be damaged, loose or the connection corroded. Removing the wheel would be best to see the wires and connector. The wires and the connector will be very obvious as they are the only things going toward the back of the spindle. The connector may be damaged, loose or the connection point could be corroded. Disconnect the connector and look at the contact surfaces. The same type of connector is at each wheel and senses the speed of the wheel to be fed back to the PCM.

      C1245 = Tire Pressure Monitor, simply reset the tire pressure monitor, once all four tires air pressures are adjusted to within the specified range.

    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.

      Since the brakes have vacuum assist (vacuum booster) supplied and actuated by the engine vacuum - start with the power brake booster vacuum hose and hose connection - work backward towards the engine connection point.
      Look or cracks / damaged hose and inspect the hose connection at the booster. Replace as necessary.

      Hook up a fuel pressure gauge to the schrader valve on the fuel rail and watch the fuel pressure closely when you step on the brake pedal. if the pressure drops off as soon as you apply the brake then check the ground wire in the trunk behind the left wheel housing for a possible poor connection or corrosion. Repair as necessary.

    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".

      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

      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

      The abs wheel speed sensors are integral with the hub and bearing assemblies and cannot be serviced separate from the hub.
