Brake booster options
 
1 Attachment(s)
Ok so I have been reading for hours about JB3 vs JB5 brake systems and so on. Then I go to summit to try and pick out a booster and MC kit and here are my options, but there is no mention of JB3 or JB5. I have a 1977 c10 stepside shortbed. Which one is the right one?

It usually depends on what size your brakes are.

OK so if my rotors are 1 inch wide, which of the three would I get?

The width of your rotors doesn't matter one bit.

Get the JB5. JB3 was a real light duty system and not many were made. Even if yours is a JB3 wouldn't hurt to upgrade, here is a release of the different brake systems.

Bottom line. Most trucks had JB5, so get JB5.

I believe the rod should be 1" though...

Can anyone else weigh in on the bore size 1 inch vs 1.125 inch?
