They make one-I just got one from Cruiserdan for a trail spare. However, for your uses, I would install a new master. They are not that expensive, and your brakes are pretty important. A new master will last another 20 years, a rebuilt master will last about 2 weeks.WckedMidas said:Like me asked above do they make a rebuild kit for the master cylender on a 89 fj-62? mine i got to pump the brakes twice to get any real pressure. and in four low i cant hardly stop the big pig?
