Brake Caliper rebuild kit

[countrypyhysician]

My Bronco has the power front disc brake minor kit, which is part number 7502 from Tom's Offroad. I have posted the link below. My driver's side caliper is stuck. I am going to rebuild the seals, and I was hoping you could lead me in the right direction as to which caliper it is so I can buy the right seals. Also, my master cylinder has a very slow brake fluid leak. Is there a new O-ring or gasket that works?

I got a reply from Tom's already. They were very responsive.
The front calipers are based off a 1977 Chevy Half Ton 4x4.
He recommended a universal o-ring kit possibly to fix the leaking master cylinder.

Tom's is great to work with. As for the master cylinder, how old is it? Seals fail for various reasons, of which age and corrosion can often be a factor, so while you may be able to rebuild the MC, putting new seals in a corroded bore doesn't generally yield the best results. Given the relatively low cost and high importance of a brake master cylinder, I would suggest replacing it with a new one myself.
