'14 TE310R weird voodoo: brakes & wheels

If I had to guess what happened: I'd say that your clamp that holds the brake line to the fork guard was slightly loose, so that every time you compressed the forks (from bumps, hitting the brakes) the slack in the brake line ratcheted down, and was now rubbing on the rotor. Eventually, the rotor wore through the line- and, voilà, no brakes.

Well, bought a used brake line from a Yamaha DT 125 but a week later crashed the bike in traffic. Some car pulled out in front of, wrecked the front end and sent me flying. Hit the windshield head first and a another parked car. Went to hospital. I was pretty much fine but couldn't walk. I'm all good now but still waiting for the insurance to buy the bike from me. They offered 3000€ but that's way too low in my opinion because of all the aftermarket parts I had on it (Akrapovic, Excel rims, new magura clutch etc.) so we're still negotiating. Got a killer-deal on a 2008 SMR 510 and picked it up. I also think it's better than the 450 for the type of riding I use it for.
