NE WI | I would do a pressure check on the low pressure hydraulic circuit. IIRC 155 PSI is the low range at 1000 RPM with warm oil. Need a 300 PSI gauge and 1/8” NPT connections.
Bern would know the exact pressure range as I’m not by my service manual.
I believe (not 100% sure) the TW25 brakes are also run off the low pressure hydraulic circuit which would explain why you lose breaks after warm up and the hydraulic pressure light comes on.
There is the oil line to the dual power control valve that has some seals and o rings. See diagram below.
