Pull some wheels off and the drums / calipers...check for leaks...

Biggest issue when it gets to this stage are the rubber hoses between chassis points to each wheel and chassis to rear axle...they swell internally and can either balloon or develop internal issues that prevent full release...

GOLDEN RULE ....never shortcut on Brake Systems
The top seal sinks into the master reservoirs when the fluid disappears, right? Such as into the calipers to take of the wear volume of the pads.
