Hi guys I have question, I received triumph recall on rear brake master cylinder replacement and some caliper spacers!! I never have problem with my rear brake and it’s working fine! Main question would you do free upgrade from old standard 12mm to new upgraded 14mm master cylinder for free by dealership or i should live it as is?? Kind not broken don’t fix? In my head 14 is bigger and better and will be advantage and maybe true couple years off trying to fix problem who has it, they finally accomplishes research and do have correct way to bleed the brake and make them work?? Any feedback who did and have good or positive feedback apprecs testediate! English is not my first language so don’t judge strongly grammar!
