[s-cars] occasional brake light on start and sometimesdifficult steering

[Wylie Bean]

Yes,  first check fluid. It should always be done with the engine running and up to normal temp. 
If it's ok, purge any air from the system. Then look at parts if those two fail to solve the issue.

So my potential problems:
Air in the hydraulic system
Hydraulic (Power Steering?) pump
Brake Accumulator
