Aero Z Posted November 17, 2014 Share Posted November 17, 2014 (edited) After having my 1" Wilwood master on the shelf for about 2 years I finally did this swap about a week ago. I have the modern motorsports rear disc package with the Toyota fronts and had the 7/8 OEM master. It seemed like it worked pretty good that way so wasn't in rush. Followed the procedure here and it worked with no surprises. Just had to adjust my brake rod out a bit. My Wilwood 1" master had check valves in both ports so removed them. My OEM master did have the check valve in the rear port (never seemed to drag at all though). I don't think its a major difference but is definitely noticeable. Pedal effort is about the same but it wants to grab harder. Seems to make the rear discs work better at first impression. Certainly looks better with the rest of the new parts under the hood. I now have a Nabco 7/8 master in the parts pile. Edited November 18, 2014 by Aero Z Quote Link to comment Share on other sites More sharing options...
