I took the Z out for some exercise yesterday and had a problem. After 20 minutes on the road it started to bog down in 5th gear at 60 mph, I down shifted and still bogged down, power key on. I pulled off the road clutch in and when I applied the brake the pedal was all the way up and stiff with no cushion, rock hard. I backed up about 50' and everything seemed normal. The brake pedal felt normal also. No stored codes in any system.
I drove about another 10 miles gassed up and was on the way home and the same thing happened again. I backed up with the same results. Either time it did not pull to either side. I spent the rest of the afternoon reading up in the service manual. The only thing I could figure out is that the master cyclinder is failing or the proportioning valve is going bad and appyling pressure to the rear.
This is probably just a C4 issue
Any thoughts.
Thanks!
