Have a 1987 B2000 that runs great.
Problem is it seems to leak brake fluid in the cab. I changed the clutch master cylinder because it was bad thinking that was it. Still getting a coating on everything under the dash and after a few weeks a puddle on the floor mat.
I did change the power brake booster a yr or so ago is it possible for fluid to leak from the master cylinder they the booster into the cab?
Thing is neither fluid is ever really low even after months.
