Good Day, All,
Just returned from an almost great 5 hr ride on my '10 GSA. About 3 hrs into the ride, noticed the rear brake starting to feel a bit spongy. At about hour 4, rear brake completely gone. Immediately pulled over. An inspection reveals the rear brake fluid reservoir completely empty. Rear brake pedal goes all the way to the stop with no resistance. There appears to be some seepage in the area of the bolt, pc 7 on fiche drawing 34-1649. I searched the forum as best I could but have not seen a similar issue noted. Before I put the bike up on the lift, I thought I would ask if anyone knows of anything to look for specifically or of any cautions I should know about.
My plan is to first attempt to tighten the subject bolt. If movement is noted, refill and bleed the brakes and watch it/test it/ride it to see if this fixes things. If no movement is noted, plan is to disassemble the joint, inspect for wear/imperfections, replace any needed parts and try her again.
