I agree. BS. I would like it explained how brake fluid can get into the housing...sounds pretty “taking advantage of a greenhorn” sneaky to me. I’d look elsewhere. Wouldn’t it make you think that if the brake fluid is leaking all over, that it would create a lubricating paste that actually retards braking action? Not make it sticky? It did on my old Toyota.
I would still double check your pedal freeplay adjustment. Doyle1950 (pm him for further details) fought with your exact issue and he chased it for a long time. His brakes would pump up, lock, and he’d have to crack a brake line in order to alleviate the pressure/locked drum. It turned out it wasn’t the drums. It wasn’t the the axles. It wasn’t the wheel cylinders. It wasn’t an out of round/bent drum. It was the pedal adjustment. He found an “old boy” shop with an “old boy” mechanic and that guy had him whipped up right in 5 minutes flat.
It was like 1/16” difference or something ridiculously small like that. Check it. Your manual will have that spec.
