Having a hyd cyl act as a parking brake is not ideal. Many have used line locks wich work ok for short duration. I know mine would bleed off withing about 30 min which would be bad if you expect you car to be parked where you left it.

Bleed back is one problem but change in temp as mentioned is another.

In the airplanes we have hydraulic line lock parking brakes. These are intended only for deplaning and starting the engines. They give you enough time to shut down and block the wheels on the jet.

At the same time setting the parking brake allows you to pull the wheel blocks and get the engines fired up. They are not to be left on continuously and in fact they have a relieve valve should a temperature change exceed maximum pressure.
