    Grinding noise from left front wheel when turning left
    Started hearing a grinding noise when only turning left from my front left tire region. Only has 50k kilometres on it. Just got a new bumper put on it after I hit a snow bank at very slow speed. It did not make the noise until a week after I got the bumper fixed. ...

      Take your car to a brake and suspension shop. A visual inspection should reveal what's going on. It is possible a pebble got lodged between splash shield and rotor. Could be bearing noise depending on severity of grinding.

      Took it in to the dealership I bought it from. Ended up being the wheel bearing on the front right side eventhough I could of swore the noise was coming from the drivers side. Luckily for me I had purchased the extended warranty and only cost me a $100 deductible. Gt500knights thank you for answering me. Really appreciate it.

      Better do both sides at the same time

      The other side will fail eventually

      May as well have two new Hub Ass'y both the same
      age & miles

      I will only do both sides of any suspension part
      at one time

      You hit something & damaged a front suspension component (common sense)
      Why else would the alignment seem off & why was that not addressed when the new hub went on?

    Changed brakes, rotors and calipers bleed the brakes and when started the car there was no brake
    Went to bleed them again and can not get any fluid. The cylinder is full of fluid.

    Why did my brakes stop working
    there is no fluid leaks but emergency brake is not working and now both front and back brakes do not work
    • GT500Knights

      As far as fluid leaks go, did you check the master cylinder? Check where it mounts to up against the booster. Should not be any leaks. And when you say brakes are not working do mean completely no braking at all when stepping on the brake pedal? Or do you have some braking power but have to use two feet to stop? If you answered yes to second question, it may be a brake booster issue.

      Did you check the fluid level? Check the reservoir. Even if you have had it topped off, you wil need the brake lines bled free of air.

      If no brake lines are leaking, check into leaky calipers or wheel cylinders. Though you may not have leaky brake lines, the calipers or wheel cylinders can leak enough to drain the master cylinder reservoir empty, and then suck air into the system.

      The parking brake not working can be due to broken or missing hardware in the rear brakes, a broken parking brake cable, or way under-adjusted drum brakes.

    ABS Light and brake light comes on. How difficult to fix?
    Just replaced front brake pads

      You would have to know what the problem was before anyone
      could weigh in on the difficulty part

      If the front pads were replaced I would think someone put the
      problem in there from sloppy work

    Why doesnt my breaks fell spongy after changing rear end and wont let bleed break line

      How are you bleeding the brakes? Need two people to do that

      You have to do all four corners & any abs module

      Not supposed to feel spongy (you got it backwards)

      They can bleed the brakes & resolve that issue
      You can do that yourself as well

      The front drive shaft you remove for now

      Then you rebuild/repair your old axle houseing or switch
      the gears to the new one

      At the moment, I suspect your brake switch. If the position of the brake switch is adjustable, I guess you could try adjusting?

    Why such a violent shaking when going 45mph and hit the brakes
    Changed shoes , calipers and rotors to no avail
    • Wray's Auto Service
      Replace or machine front brake rotors should solve this issue.

      If the front brakes are OK - new pads, brake shoes and rotors, then check the front wheel bearings - be sure the bearing preload (tightness / looseness) when the rotors are installed is OK.
