Breaks
I put on new shoes and wheel cylinders all the way around my coach I bought a master cylinder but I think it’s the wrong one I bled the system but it’s not getting a pool pedal so good I bought the wrong master cylinder if so what is the correct one.
Don’t know anything about anything older. Hope that helps and best to verify/ confirm this info, make sure you can return it if somehow you still end up with the wrong one.
