    Front brake discs

    Hi guys, it's been a while, I've just had my 15,000 mile service done, prior to that I had noticed the front end pulsing a little under breaking, low and behold, it turns out the discs were warped, so I had them replaced, OUCH, but I did retain the old ones and was interested to know if I could have them re calibrated or trued at a cost preferable to the one I've just incurred,  should it happen again, I've been informed that it is a common occurrence in the bike world, any info would be greatly recieved.
    I'm in Yorkshire England, if any one knows of any one
    Cheers all

    I think there is a slight warp in mine as well.........only really noticable under hard braking.

    Is there aftermarket available or do the have to be Honda??
    (I'm thinking EBC or Brembo)

    Preventing that is simpel.
    DON'T ever hold your front brake at traffic lights, intersections or where-ever when standing still.
    When the brakes getting hot due to braking and you hold the brake on while standing still the place where the pads touch cool different than the rest of the disc causing them to deform.

    If the bike rolls and you cannot hold him with your leg(s) you have to use the rear brake. When rolling back it's also the better brake for get going again.
    The rear brake disc doesn't get as hot, is smaller so less likely to bend end when it does you hardly notice it because you rarely use it.

    Thanks Ray, I'll bear that in mind.........

    Any idea about the brake disc question, with regards to aftermarket availability??

    Straitening is possible but you have to check locally. I think it cam be expensive anyway.
    Aftermarket is often cheaper and can even be better while cheaper. OEM is not holy and even OEM is in the wear and tear parts mostly just a regular brand in a very expensive Honda box or blisterpackage.
    The OEM discs and pads are mostly Nissin for Honda.
    Especially Honda made a bad deal for the packaging because repacking makes it double the price.
    For my Ténéré the OEM discs where cheaper than the aftermarket product available.
    For the CT they where replaced under warranty. Was already bad on the testride but at first the vibration seemed to be caused by the square and cupped front tyre. That was at almost 24k/km and after the change a have them over 60k/k in use without any warping but i am very strict in not holding the front brake in while standing still.
    Also do a lot of mountains, even had some fading due to the hard riding on steep roads. When you hold the brakes at the end of those mountain roads you can throw them away.
    I have uploaded some video's from my last trip on my YouTube channel, also the Stelvio.

    I honestly never considered holding the brake on could be causing problems. I will try and stop the habit.

    What is your YouTube channel called??

    This is the Stelvio but not the first part of the series.

    Morning. I’ve had a few ST1100’s over the years and one of those had warped front discs exactly as you described, and a 1200 Triumph now I come to think of it I just put up with it but as already said holding the front brake on while stationary I never do, same in the car actually. We don’t see it but they get extremely hot and are relatively thin.
