Please save the invoice. Once I decide to move with the legal letter, could I get an invoice copy with your personal info redacted, if you don't mind? I would use it as evidence of what Triumph is doing and their crazy request for me to returning to OEM.Well I got my '17 Thruxton R back from the dealership on Saturday. They rebuilt the front calipers and replaced the master cylinder after replicating the issue (stated on the invoice). The parts listed on the invoice were Triumph parts, and the pistons were the standard OEM grey pistons. The brake feel was marginally improved, but I can tell it was more from having put new pistons and seals in and 'resetting' the piston position than an actual fix - similar to what would have happened if I'd just moved the pistons out, cleaned and lubed them. I'm guessing a few miles down the road and some brake pad wear and I'll be right back where I started.
My initial squeeze on the brake did not go as far to the handlebar as when I dropped it off, but still travelled more than I would expect. A second quick squeeze (that double pump we're all talking about) was marginally firmer, so the symptoms are still there.
Not like I had anything to lose, I don't ride it much in the winter and they covered everything on warranty. Not overly upset with the dealer or service department, they did what they could. I made it clear when I dropped it off that replacing the original pistons with new OEM wasn't going to work. But the service department is limited by what they are allowed to do. They're only going to replace OEM with OEM when doing warranty work. Until an actual recall is issued for a defective design, this is what we're getting from Triumph.
Time to rebuild it right myself with the proper parts. Thanks to everyone on here who has contributed to finding the true root cause and proper fix to the brake issue. Looking forward to having the premium brake system that I paid for when I bought the bike new. Hopefully one day the guys at Triumph or Brembo will figure it out.
