[QUOTE="Brodie, post: 1320741, member: 3372"] First things first, wash the splashed brake fluid off your body work. Looks to me that your dirty brake fluid went into a hydraulic lock from the usage. Dot 3 & Dot 4 is hydroscopic - it absorbs water. If it hasn't been flushed out for several years it must have been quite dark, which means it was saturated. When you used it extensively on that long downhill grade called Interstate 80, it got hot enough to boil the water in the brake fluid, causing the caliper to grip the rotors. From the looks of it it was your front brake circuit that failed as the spray came from your left front caliper. Sounds like it's time for a brake job - flush, clean, possibly replace the overheated / warped rotor, and new brake pads. These pads have been overheated and are most likely cooked. Hopefully you can find parts easily, the nice thing is there are several salvage yards in the area (Rancho Cordova) that might be able to help you out on a rotor or two. Good luck, the good thing is your bike is among friends, who will help get your bike straightened out. Keep us posted.
