14b disc brake
I used 85 3/4 ton rotors and calipers, because I wanted
everything front and rear to interchange. If you go that route
they will probably ask you if you have JB5 or JB7 calipers. The
difference is piston dia. I went with JB7 the bigger of the two.
If I had to do it over, I might try the Jb5 to get better line
pressure. I have 1 1/4 Dia. 3/4 ton master cyl. and adj.
proportion valve.
For the emergency brake I used seperate Fr and Rr line locks.
Have used this setup for over a year with no problems. Also
with the Sky brackets and this caliper the bleeder will be at the top.
Hope this helps.
