Some of this will be redundant, but I just R&Red a rear caliper this afternoon, so sizes are pretty fresh in my memory:
Caliper to knuckle: T50, 30ft-lbf.
Ebrake bracket to caliper: T40, or some rebuilt calipers used 14mm hex bolt. (FWIW, reinstalled with antiseize, as this particular one was a bear to remove).
Ebrake actuator lever attach: 18mm.
Ogre taught me this...
To install Ebrake actuator lever:
Install seal, antifriction washer, then lever, then self-locking 18mm nut...
All manuals I have (including Helms factory manual) show seal and antifriction washer swapped... don't do it that way! Use lots of caliper grease on this area. Key thing is: the lever must move freely, w/o binding.
Hex on Ebrake shaft: 14mm.
Flexible brake line to strut: 13mm.
Suggest you read brake articles in Ogre's Cave thoroughly. They are a great help to me. Obviously, if there's one thing that needs to be done right, it's brakes. Good luck,
!
