    Brakes locked up, pedal went hard; what is the cause?
    Car has@ 137K miles and is fairly reliable. Brakes locked up once before and we had calipers and pads serviced. Repair lasted several weeks and reoccurred while driving and engine warm. No code info available and the engine light is on.

    2004 Hyundai ELANTRA Fuel Delivery question
    After replacing the fuel pump/assembly on a 2004 Hyundai ELANTRA it still seems fueled starved after sitting over night. Is it bleeding off pressure because of a fuel line leak between pump and engine?

      Possibly - have you checked for the fuel line leak - from the fuel tank to the engine? If not, then start with this step.

    Grinding noise when moving and feels like slowing quickly when coasting / foot off gas
    Hi, my car is making a grinding noise when in motion (particularly noticeable during acceleration) and also feels as though the vehicle slows quickly when coasting or my foot isn't on the gas. This happens all the time.

      Your brake calipers may be worn out, causing the the pads to not retract properly. Hydraulic pressure is holding the pads against the rotors, rapidly wearing the pad lining down (and you've probably already got the lining worn out--down to the pad backing). The metal to metal grinding sound is the metal pad backing contacting and dragging against the metal rotor surface. Check for deep grooves on the rotor surface.

      The other possibility is that the wheel bearings are bad.

    Brake Problems No Brake Pressure!!!!!
    I had the same exact problem happen to me twice in my 2013 GLS Hyundai Sonata. When i went to press the brakes it went all the way to the floor!! I took it to my local Hyundai dealer and they couldn't find any problems. So they called the Hyundai headquarters and ...

      Since the vehicle is still under warranty - have the local dealership repair / replace the brake master cylinder, in addition to inspection and repairs of any brake fluid leaks in the system. Make sure the dealership provides you with written records for all repairs that clearly indicate the: exact issue, finding and repairs in detail.

      All the repairs will be done at the dealership / manufacturer expense - not at your expense nor cost.

    Have to top up brake resevoir, but no leak otherwise brake are ok
    60000 miles. in good condition.but still have to up brake reservoif, no sign of leaks on the wheels or on the ground

      OK - is there any question with the information provided? First question - how often does the brake master cylinder need refilling?

      Aside from the obvious and usual external leaks, there may be an internal leak of brake fluid from the master cylinder to inside the brake power booster unit - mounted just behind the master cylinder.

      Probably needs to have the rear brakes lokked at. I'm sure it is nothing very serious or unsafe.

      Your Hyundai has what is called false abs activation and the cause is a bad wheel speed sensor. Since there are 4 sensors you cannot know whichj one is bad unless someone reads the abs codes with a scan tool that is Hyundai ABS capable. You could buy one of these scan tools for around $200 if you are a DIY mechanic on your own vehicles because most shops will bill you too much to check the codes for you unless you have a good relationship with a local shop and he does it for you. Otherwise, if you bring it into a shop and tell them you are getting false abs activation they will know what to do.

      Not sure about the safety either - as there is no way to tell / or inspect via the internet. Have the vehicle inspected by a trusted local auto repair shop. To locate one; use the best method - inquire by word-of-mouth - and use the 'Find-A-Shop' efeature on the AutoMD website.

    Why does my car hesitate when I step on the gas? This is after catalytic converter was done.
    The check engine light is on and happens afer stopping.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

      It could be just the brake pads being noisy from being glazed pretty common when people do a lot of stop and go driving .

      Have the brake system inspected, particularly the brake pads - ideally by the same repair shop or gagrage which performed the work last time.
      Make sure the anti-squeal gel and anti-squeal pads are installed on the backing plates of the brake pads - where the caliper pistons contact the brake pads, on both front and rear wheels.

      Be careful - often it is not recommended to turn (machine) rotor surfaces. Much less expensive in most cases simply to replace the brake rotors. One question - why was the recommendation made to turn the brake rotors in the first place?

      Check the many on-line auto parts sources, such as; www.autopartswarehouse, or for the replacement parts. For example, they (RockAuto) list the front brake rotor from around $28.00 each for your vehicle; Bendix part # PRT5831 or Raybestos part # 980419R - just two examples for the various brands available.

      I paid $23.00 for Midis to provide me with a brake inspection, because they are sqealing and the mechanic told me I needed to get the rotors turned, and purchase a new set of pads for the front end of my vehicle. They want to charge me around 170.00 to complete the job.
    • Jimm

      The squealing noise can usually be corrected by applying some anti-squeal gel to the brake disc metal backing plate on the inboard position brake pad. This would cost you less than $10.00.
      Generally, the front disc brake replacement (new brake rotors and new disc brake pads) should cost less than $100.00 - total for all the parts needed.

      Is the Midas repair shop going to apply the initial $23.00 charge for the brake inspection (at most shops this is free) to the cost of the repair? If yes, then it would make the costs somewhat more acceptable - still no new / replacement rotors either.

      Second, how much disc brake pad material remains - how thick is the brake pad friction material? Typically, the brake pads are replaced when the friction material thickness is around 1/8' to 1/4" remaining.

      Check the many on-line auto parts sources, such as; www.autopartswarehouse, or for the replacement parts. For example, they (RockAuto) list the front brake pads from around $18.00 for your vehicle, such as; Monroe part # GX924 or Raybestos part # SGD924C (ceramic pads). So, with the various on-line parts sources; you have $18.00 for the front brake pads and around $56.00 for both front rotors - total parts cost = $74.00 for new brakes on the front of your vehicle. Much different than the quoted $170.00 price - and this higher cost does even include the new rotors! WOW!

      Check the 'How-To-Guides' feature on the AutoMD website for the specific steps to replace the front disc brakes; pads and rotors.
