    What could be causing the constant scraping/grinding from right rear drum brake? Temperature is hot after driving.
    Noticed the back right tire is slight leaning in.

      Most likely, the issue is worn drum brake shoe (friction material). Remove the rear brake drums for a thorough inspection.
      If the brake material is gone and the brake shoe is contacting the drum metal-to-metal, then you have to replace these items; brake drums (both sides), brake shoes (both sides = complete axle set), brake spring hardware (comes in form of a kit).
      The parts are readily available; try these on-line sources;,,, - to list only a few possibilities.
      In fact, they (RockAuto) list the rear brake shoes (axle set) from around $8.25, the rear brake spring / hardware kit from around $4.60, and the rear brake drum from around $16.50 (each) - for your vehicle.

      pedal goes soft as in to the floor? if so that's means there is a leak in one of your lines soft it means there is still air in your lines are you using a self brake bleeder system or having a friend help you?

    What went wrong during my oil change?
    I went to wal-mart for the oil change, and that's probably not ideal, but it's never caused problems before. it is having trouble changing gears, the brakes are less responsive at low speeds than they were, and it shudders at low speeds. And I'm not positive but it ...

      Are you saying that after you engine oil change (not transmission oil) that all these problems began?

      I think the walmart oil change person may have broken/cut or disconnected a vacuum line. Check around the jack points, the oil filter and the oil fill cap for a vacuum leak.

    Why am I losing brake pressure and fluids
    While in gear I use brakes and come to stop but when excessive pressure is applied to the brakes the petal depresses to the floor the picture included is a part covered in brake fluid if that is the problem what is the rough cost to replace it?

      Several possibilities; leaking brake fluid from the system; front brake calipers / hoses, rear wheel cylinders, flexible hoses. May also be loss of fluid from the brake master cylinder. Cannot tell for certain without a thorough inspection.

      The picture you show is a pressure differential valve . Brakes apply about 60% to the front tires and about 40% to the rear . The master cylinder puts 100% to this valve . Then the valve splits it to the front and rear . Can't tell by the picture what or where it is leaking but no matter what it shouldn't leak at all .

      That is a failed part some problem be care not to strip flare nuts and go to andsearch for the brake proportioning valve. Cheaper than dealership and exact fit.

    Why don't any of my brake lights work when I press on them.
    I have 75000miles on my car. All of my lights work except the brakes. I had the bulbs change and lights still don't work.

      Check the components common to both brake lights; the brake light switch (mounted under the instrument panel on the brake pedal arm), the wiring / connections common to both lights, the brake light relay or fuse.

      Check the many on-line auto parts sources, such as;,, and - to list only a few sources. For example, they (Rock Auto) list the brake light switch from around $2.80 for your vehicle. Standard Motor Products part # SLS342 (Same as OEM parts #9381038100, 9381038110)

    Braking problem
    Couple months back I was involved in an accident (front end damage) the vehicle is still functioning however when in gear when brought to a stop there is a grinding sound however when in neutral braking is smooth

      Check and see how far beyond the front grille the damage extends.Jack the wheels place on jack-stands .Remove the wheels and see if the rotors or calipers could have been damaged or if something is rubbing the wheels. Check the trans. shift mechanism to see if something is damaged. If the problem only started after the accident something must have been damaged or pushed out of place by a damaged part.

    Right front brake won't release
    I'm having a problem with my right front caliper not releasing. I drive just a short distance and the right caliper engages but won't release. I have replaced the caliper and the brake line, but the problem still persists.
    • HouseCallAuto

      That would mean that the master cylinder is maintaining residual line pressure going to that wheel. When the caliper is frozen if you loosen the bleeder and the caliper immediately releases then that would prove the master to be the cause most likely.

      Sounds like the rear pads or shoes are worn, and you have metal to metal contact. Inspect the brakes asap

    Brakes and maybe another issue?
    Not only when I back up does it squeal but also when I'm on the freeway and now on surface streets. So pretty much all the time the car is making noises

      Usually, the brake high-pitched sqeal is the disc pad wear sensor contacts the brake rotor - giving an audible warning about the pad thickness - getting thin and time to replace.
      Try the many on-line auto parts sources; such as -, or for the replacement parts.

    Once back calipers are froze how do you unfreeze them
    Changing back brakes and calipers would not retract

      Try a penetrating oil or spray to soak the frozen pistons. In the long run, it may be less expensive simply to replace the frozen calpiers. Try the many on-line auto parts sources, such as; or for the replacement parts.

      Have you checked / replaced the front wheel bearings / hub assemblies - due to wear? The other possibility is the front disc brake rotors are warped - fairly common. If the front rootors are replaced, they are fairly inexpensive; try the many on-line auto parts sources, such as; or They (Rock Auto) list the front brake rotors from around $14.00 each for your vehicle.

      Did you bleed the entire brake system - and not just the left front caliper? Remember that the residual air can migrate into the entire brake system causing the low pedal condition.
      Try bleeding the entire brake system - beginning with the wheel furthest from the master cylinder.
      11/15/2012 Lone_Star_38
      Thanks Jimm. No, I did not try that one yet. I will bleed all wheels and see how that one goes. Thanks again. I will let you know how it turns out this weekend. Joe
