hey guys im about to change my diff in my vl from a gay drum brake 1 to a disc 1 out of a vl calais just wondering if i have to use a 1 inch master cylinder and double diaphram booster or will the standard 15/16 master cylinder and booster be fine ?
NA calais came with NA front brakes and disc brakes at the rear as standard and they only used the 15/16" and single diaphram booster.
So yes it will be fine.
if ur keeping the smaller brakes i dont see any problem with it, i brought a complete v8 brakes package, inc diff/ 1" master/ booster/ and rotor's calipers, should be goin in this weekend or next, goodluck mate, should be fine anyway
