I have wasted hours and liters of brake fluid and cannot get working brakes on my 2800 CS. So, I need a master cylinder. Or a rebuild kit. Using a NOS master but it must be bad. I have wasted so much time on this and am very frustrated.
Hi Steve. Should be the 23.81 if I understand correctly. I can take apart the old one that was on the car and measure the bore. It also has that residual pressure valve for the rear drums, but I can work around that.What is the diameter you need? I think I have a new one that i mistakenly bought for 3L that is wrong size for mine. I’ll gratis it to you if it’s a match.
