"Washboard" feeling during breaking

Discussion in 'General Motoring' started by HyperCube33 \(Life2Death\), Apr 9, 2007.

  1. When I break now my car feels like the front end is going over a washboard
    dirt road. The harder I break the more the feeling is pronounced. it tends
    to feel like its shaking rapidly back and forth quickly between the two
    front wheels, though I have no idea what causes this. Before this got worse,
    my break peddle was quite spongy.

    Much thanks!

    It's "brake", by the way.

    Most likely explanation is that one, or both, of your disc rotors is warped.
    Any tire or brake shop can check this for you, and -- if there's enough
    thickness left -- correct it as well. If the rotors are too thin to be
    machined, they'll need to be replaced.

    IMHE, Saturn OEM rotors are subject to SEVERE corrosion on the inside brake
    surface and are often unserviceable well before the pads wear out. Suggest
    careful inspection.

    I have had MUCH better service from offshore rotors costing a third that of
    the OEM (or other 'brand name') replacements. These offshore rotors cost
    very little more than the normal cost to have rotors turned down (which
    usually leaves them so thin they will be prone to warp)

    Good luck, YMMV.

    Before this got worse,
    And "pedal" also.

    It's more likely uneven deposits of friction material on the disc/drum
    surface (perhaps caused by rust), and not warping. See article here if
    you'd like more info:

    Regardless, having the rotors/drums machined, or replacing them altogether
    has always taken care of it for me.

    Very likely warped or uneven front rotors. Heavy driving/braking habits
    caused this for me so I solved the problem by replacing my rotors with
    Brembos (solid, vented, not slotted for ease of maintainance )and pads with
    Akebonos. Violla! no uneven brake wear and enhanced stopping power! I also
    recommend having the rear drums resurfaced or replaced if needed and replace
    the shoes with Wagner performance. Just about any parts place will sell
    these and they wee less expensive than OEM thru Saturn shops.
