GTB/ G506 Brake master cylinder question

Post by 1943Willysgpw » Tue Oct 31, 2017 11:43 am

Would a master cylinder from a G506 etc. work for a Ford GTB? If anyone knows of a known good replacement option or supplier, please tell me. Rebuild kits also please. Thank you.

The ONLY CORRECT Master Cylinder for your GTB is a WAGNER F-4572. There are a few that look the same, but they are not equal in capacity or spec to the F-4572.

Thank you. Now the search is on for a kit or whole part.

Mr. Leo, since I have you on here, can you tell me which way this rod is suppose to go and how it works? My spare carrier has this latch under it and a rod running out of it. It is frozen up and when I soak it in fluid, I do not want to just "yank" on it in the hopes that I am pulling it in the right direction. Thanks.

And, no, the master cylinders for G-506 are not the same. Will not even bolt up.
