Me too. Just been into dealership for no back brake. Told me special brake fluid from Triumph. 300 miles on and back brake going spongy. Sometimes "kicks back" which I assume is ABS related. Will be calling them on Monday to find out what to do. I've been proud of this British success, I only hope I continue this opinion.
Mine is now laid up, out of use. Triumph no use, dealer no use. Not in any rush to ride it again unfortunately. Think I’ll buy something that works in the meantime, possibly with brakes that work.
It’s weird, you’d think they’d either all have the issue or none have the issue. Given Triumph clearly have no clue what causes it, I’m at a bit of a loss to understand what’s going on as well.I’m very disappointed to hear of brake issues on the new Rockets. I must have dodged the bullet since I have 6k on the TFC and no issues ,YET.
That's how I change my rear brake fluid. Bleed the rear brakes, then go for a ride hammering the rear brakes several times to get the ABS to cycle. Bleed the brakes again. This will purge the ABS of the old brake fluid and any air sitting in the module.
Dealership replaced standard fluid with race fluid, 400 miles on and the problem seems to have been solved.
Race fluid? (5.1)
High heat fluid which in time will not work.
