Thread: Removing Rear Brake Disc

  1. #1

    Removing Rear Brake Disc

    Thought it would be an easy switch to replace the rear brake pads and disc, but I cannot figure out how to get the rear disc off. There doesn't seem to be a way to get a Torx bit in that confined space. I look on google and youtube with no luck. Am I missing something?
    Any suggestions?

    Thanks - Robert

    Why the disks (rotors)? I can understand the pads, how many km or miles do you have on the scooter.

    I have replaced the pads but not the rotors (disks) I now have close to 48,000 with no worries

    justscootin,

    For reference, at about how many miles did you replace the pads at? front? rear? parking or all?

    Thanks,

    Thanks. I guess I have to look for a really short T-40 Torx bit.

    I have 30,000 miles. This is an aftermarket upgrade. I never been really satisfied with the rear brake, so I thought I would tackle that first and avoid having the dealer do it.

    I ended up using a T40 hex bit and a small adjustable (crescent) wrench. A complete PITA but do'able. Be sure to use anti-seize on the bolts when you re-install them.

    BTW, Did you go with BMW discs ($200 EACH) or the aftermarket Brembo ones? I went with the aftermarket, seem to function identically at 1/3 the cost.

    I went with the Malossi Whoop Discs. I ended up ordering the shortest T-40 I could find on Amazon and will be re-attempting coming up on the weekend.

    Cool, good luck! Can you post the supplier and part number for the Malossi disc?
