master cyl.

A bodies manual discs/drums 15/16" on the bore works well.

Smaller bore masters give softer pedal to push and a little more throw. Dropped down a size on the B body too on the manual brakes, drums/drums
15/16" bore much much better !

Willwood discs on the front , unknown on the back / was installed new by the guy I bought the dana 60 from when he built it .
It does have a 15/16 master cyl on it !!
NEW everything , including braided brake lines on front.
