David Godfrey's '94 Ford Thunderbird Master Cylinder Upgrade
David has developed a master cylinder upgrade for the Merkur XR4Ti that utilizes a lighter and less expensive unit from a 94 T-Bird. Regarding the master cylinder, David writes:
"I wanted to find one with a bigger diameter piston bore if possible as well as a lighter one since the XR cylinder is cast iron. Never liked the XR cylinder as it is heavy and expensive. Ended up using a cylinder from a 94 T-bird, non-ABS with a 4.6. The T-Bird cylinder has a 1.062 in bore vs. the XR's 1.00 in. "
Below are some photos highlighting this modification:

"The brake lines need to be changed as the XR had two ports for the front line where the t-bird only has one. This worked out in my favor as I want to install a line lock (for drag race burnouts) and I need one line common to both front wheels to do this. The rear line was going to be changed anyway since the stock proportioning valve was going to be removed."
