I just purchased a 1989 f600 rollback truck that had been sitting for four years. This truck has Lucas Girling brakes and the parking brake chamber is run with power steering fluid. My problem is the passenger side brake chamber will periodically spew power steering fluid and then will act normal with no leaks. I have put less than 100 miles on this unit, so I don't have much experience with it. My question is why the leak is sporadic? How would I trouble shoot? I can't seem to find any diagrams on the internals of the brake chamber. Is there a way to rebuild the brake chamber or must it be replaced?
Thanks for any input
