Has anyone fitted a Wilwood master cylinder as part of their braking upgrade at all?
I am fitting one to replace my MC (early 280ZX unit) as it’s leaking. Good original units are hard to come by and the seals sets are now unobtainable. Had two ‘good‘ second hand units fail, so now is a good time to do a little upgrading.
The question I have is to do with the check valves. The Wilwood unit has one in the rear circuit and the advice from the company is to remove it if the car does not have rear drums. The check valves are so say not needed for disks as they keep pressure in the lines and cause the pads to drag. However, the original MC had check valves in both front and rear circuits with no adverse issues. Having read a bit online in the various z forums there is a difference of opinion as to whether you leave them in or should remove them.
So long story short, has anyone got experience of doing this and if so what did you do with regard to the check valves? I’m of a mind to install them, if it was good enough for Nissan should be good for me?
Any comments from actual experience gratefully received
