My 1070 has slow lift with remotes when engine is hot but has a problem with brakes and steering at any temp. If i step on brakes i lose my steering. I dont have flow meter but was hoping that someone would know if maybe i had problem with a diverter valve or pressure relief valve. thanks Don

Don;
I'm taking you to mean a 1070 Case farm tractor, not a compact, about 100+ HP. If so I did own two of them when we farmed. They were good reliable tractors but they did have one of the problems you describe. They would often lose braking when other hydraulic things needs were being seved. I'm being of little help other than to say yours isn't the first 1070 with that issue, we never did resolve that problem, just learned to live with it.
I never had the other problems like lack of pressure when fully warmed up, for that I would suggest a complete change of filters and the proper fluid. The first thought allways is a worn pump, but i'd sure try a fluid and filter change first. The two transmission/hydraulic filter housings that hang side by side look identical but do take different filter elements, it's easy to get the elements mixed up. If it is still attached there should be a decal on each filter housing telling which filter goes in which housing, otherwise your owners manual will tell you. I'm pretty sure the elements will fit either housing but the difference is the micron rating of the elements, If I remember correctly one is a 25 and the othermis a 10. Not everyone will agree with me on this but I've always insuisted on using for example CaseIH HyTran fliod and CaseIH filters. Some universal fluids will interchange but most will not mainly because of the additives that are specific for the type of wet clutches for example that a tractor may use. The 1070's for example had dry brakes but most all other tractors have wet brakes, almost always brake chatter can be traced to the wrong fluid being used.

With out testing we will never know! All of the older tractors had the diverter valves between steering and brakes as well as pulling from the rear hydraulic unless they were a two pump system. You definitely need to get it fixed as no brakes or steering is a no use issue! ....
