    Brake pulsing is usually the result of pad residue on the rotor which causes uneven friction on the swept area of the rotor. This residue is deposited when you hot brake to a stop and keep/retain the front brakes clamped on the hot rotors.

    This practice transfers some of the material in the pad to the rotor resulting in pulsing brakes (especially true for front brakes).

    The rear can also develop this phenomena but not as frequently. The typical fix is to sand the brake rotors to restore a fresh metal surface and remove the offending pad residue.

    When hot stopping, one you are nearly stopped, release the hot front brake and use the cool rear brake to hold your position.

    Motorcycle brake rotors should not be resurfaced. There is not enough material to allow resurfacing.

    New rotors are the safe way to restore reliable braking along with quality pads.

    DO NOT resurface your rotors, if they have either groves or are less than the minimum thickness, replace them, come on guys, they are not that expensive and if you are looking to save a few bucks this is the WRONG place to do it. For years none of the major manufacturers have recommended resurfacing, break systems have become one of the most technically advanced areas of most bikes, this time, do the right thing.

    $650 + shipping to replace the rotors on an 1100gs with oem parts.

    that is pretty damn expensive to me, given what they are ( a steel disk with some holes in it)

    I would not use OE brake parts due to expense.

    I use EBC rotors and pads. Excellent quality and less than 1/2 the price of OE.

    Bike Torque Racing in the UK - extensive selection of Brembo pads and rotors IN STOCK.
    www.biketorqueracing.co.uk.
    My order was shipped almost immediately and arrived in DAYS - shipping from Britain must not be all that difficult any more. And they have the Brembo logo stamped into the metal.

    About $500 plus $50 shipping.

    Cutting corners on the BRAKES??? Maybe not.

    I don't understand ordering brake parts from the UK. There are several reliable dealers here in the US that sell and support excellent aftermarket brake parts such as brake lines, pads and rotors. I have replaced both lines and rotors with aftermarket from these folks...

    There are others, as well.

    My rear replacement EBC rotor was about $130.00.

    One technique to resurface rotors is to use new pads, as in 2 or 3 sets in a row to wear down the high ridges.

    This is of course if you are really in need of using up spare time.
