SMT ABS Rear Brake Failure

Post by motoyoyo » Tue Nov 12, 2019 4:25 pm

I have a 2013 SMT with ABS brakes. I bought the bike used at 3k miles in basically new condition. Lately I have been riding hard on tight canyon roads trying to keep up with my son on his 690 Duke. I have had to use both brakes heavily to haul the bike down on super tight turns. The front brake has always worked flawlessly, but the rear brake will fail and disappear if I'm hard on both brakes. I mean, it will go away completely with one big "Clack" and it's freewheeling. Pretty disturbing to say the least, when I have to either stand the bike up mid corner or hit the front brake even harder. I tried shutting the bike down and restarting by holding the ABS button in, which I assume will turn off the ABS. Same result.

I have bled the rear brake caliper by removing the rear wheel and tilting the bleed screw up, on the caliper to get all the air out. Pumped a ton of new brake fluid through it until it came out clean and fresh. No help. I have never experienced this situation with any bike before, and just wondered if this is something that is unique to the ABS on this bike. I had a 2010 SMT without ABS and both brakes worked great all the time.

I figured out a solution to my rear brake problem. I parked the 990SMT and brought out the 990SDR instead. Much easier to keep up now. Fantastic non abs brakes, lighter weight, more power, sharper handling. The SMT will remain the bike of choice for sport touring duties, but the SDR is much better suited for tight canyon blasting.

By the way, this photo was crafted from two separate pictures by a pro photographer that hangs out here on the weekends. We weren't actually riding this close together, more like about 30 feet apart. Cool picture though.
