Seized rear caliper, boiling brake fluid

Seized pistons in Motorcycles I bet is fairly common. My Suzuki did the same thing. Fortunately I was close to home, and didn't damage the rotor. I just got a replacement caliper from a dude that was parting out his wrecked Suzuki. It's helpful to change the brake fluid every year or two. Keeps the seals pliable, and limits moisture intrusion. Moisture causes rust and that's was seizes the pistons. There are other contaminants of course, but flushing the fluid regularly limits all of that.
 

Shoot..... I got you and alpental confused with one another.... sorry about that.

I fixed my previous post.

Either I have seen a lot of 2014 Roadsters are having problems or I've been seeing alpental's posts about the problems. That sucks either way.

Before buying the Rocket X, I had read in a lot of reviews of 2014 having this same problem. Almost kept me away from buying the bike. I have no idea if Triumph made any changes but have not read anything about the 2015 or later having this issue.

I just went through the bikebandit.com OEM part details for '11, '14, and '16 Roadsters and all parts of the rear brake system have identical part numbers. I guess that doesn't mean Triumph hasn't updated brake system parts with known failures and made them applicable across all Roadsters (I can't see a part number history), but they're all the same.
 
i am responding to this with little researching. i fell like i have the flu. if it helps ok and if it dont say what u want.
i was wondering that the brakes sezing up would be the problem for felling slaps on the foot pedal. my reasoning behind this is when u have a warped rotor it puses the brakes and u could probably fell the pedal or fell it bouncing around. just a thought dont shoot the messenger.
 
"the problem for felling slaps on the foot pedal" What? I think you mean "feel" not "fell". Either way, the rear brakes were just fine immediately leading up to this incident. No pulsing or grabbing of any kind, just smoother operators. And the past 50ish miles were all easy cruising highway miles, nothing very aggressive.
 
The rotor might not actually warp unless and until it cools unevenly, so you wouldn't feel pulsing until it cooled off, and you went out riding without making repairs. When mine seized the brakes just stuck on and the pedal got hard as a rock. Fortunately the rotor did survive. Though recent measuring indicates it is near end of life wear wise.
 
What i was thinking is that truimph used some defective parts back in 2014 and did not become aware of the problem untill it surfaced. Harley did the same with 2012-2014 clutch baskets that were not heat treated properly and refused to acknowledge the problem.
 

HD missed a perfect public relations coup with that! Once it was discovered that the baskets were badly treated, they could announce, "We will replace these defective clutch baskets, and the cost will be borne by the supplier, and no money charged to the customer." That's taking care of your customers and leading people on the fence to believe that HD might take care of them. Such a great way to do business....but they dropped the ball.
 
My HEL Performance stainless steel brake lines arrived today. The carbon black color looks great and the lines seem well made. Waiting on a few more parts before I change the oil and rear tire and then take her in for her 20k mile service, warranty claim on the rear braking system, and installation of upgrade bits (brake lines, coolant hoses).
