    Brakes siezed while on the move.

    Hi everyone, I currently up the North West of Scotland and I was riding part of the NC500 heading towards Drumbeg on a single track road. I thought my bike was loosing power and got to a slow part of the road, I throttled off and my bike dived down and stopped me dead in my tracks . My pal behind was lucky not to run in to me. Both wheels were jammed solid  I poured water on the rear caliper and it was red hot and I discovered that the front right caliper was the same. The water done the trick and the brakes released. My mate who also has a Trophy said that the rear brake is linked to the right hand front caliper. I do use my back usually but for the rest of the day I never touched for the rest of the day and ot seems to be fine. Does or has anyone else had this happen. Thanks.

    As I said in previous days in another post, yes, on one occasion, the same thing happened to me.

    It is necessary to do a complete revision of the calipers, since it is possible that some seal is defective, piston is stuck etc.

    You should also check the two front discs and the rear one, especially the front one on the right side which is the one linked to the rear brake, it is possible that due to overheating, some of the brake discs are oval.

    @ Digital: Yes you are correct. But if you poured water on hot disc, i am sure you have to renew them now too.

    No, I did not put water on the disc, the truth is that at that time I did not think about that, I waited half an hour for it to cool down but when that happened I was in Norway and when I returned home, I replaced the brake discs. front by some Brembo brand brake discs. First of all, I worry about my safety and my wife if she travels with me.

    I had the same problem on my little scooter with the rear wheel almost locked on and brake lever firmed up.  Someone in a scooter group suggested changing the brake fluid (not done for four years). Problem immediately sorted.  It turns out the brake fluid absorbed water to a level where it boiled at a much lower temperature.  When I changed the brake fluid, what came out first actually looked more like water than brake fluid.

    Hi, just an update on my brake issue. I took the bike to Edinburgh Triumph who advised that the problem had been a seized real caliper. They overhauled the caliper, fitted new pads, bled the whole system with new fluid and cleaned the discs up. All for a very reasonable 135. I was pretty pleased with that. Cheers everyone.

    Couldn't have done it much cheaper myself, All new parts alone would be over 80.  :028:
