    Default Toyota Echo brake vibration

    Off topic/French stuff I know,but... daughter's Echo auto has slight vibration through steering wheel when brakes
    applied.And first braking after sitting overnight produces pedal vibration and once gave no brakes. Have removed the discs and checked for warping - none.Car does not veer when braking. Hve applied hand brake in neutral - smooth as.Any ideas from the more knowledgeable?

    Lou,
    "Have removed discs ,checked for warping?" Disc run-out or warping is usually done with discs on car. Secure them to the hub with wheel nuts, *tighten to specified torque. Check run-out with dial gauge.
    Handbrake use would indicate front brakes. Can't offer explanation for your "no brakes" report.
    A good look over the front suspension bushes wouldn't go astray.

    * This applies when refitting wheels.

    Hi Lou; if the discs are quite worn, they can have thinner sections where the disc has worn more than elsewhere. It only takes a fraction of a millimetre of difference to make it shudder a bit. Skimming fixes this, of course as long as there's enough thickness in the disc to allow it.

    I'm not sure of the design of the calipers, but worn caliper slides could cause shudder as well.

    Mind you, these wouldn't explain the temporary loss of braking after sitting overnight.

    I have no experience with Toyota's, but one of my cars can have similar symptoms due to front suspension wear eg bushes, poorly balanced wheel etc.

    Wheel bearing possibly, but doesn't explain the no brakes, maybe try front to rear wheel swap or some pagan sacrifice, but you would probably have to consult the great god " GOOGLE " for the appropriate item.
