First check you have correct pedal free travel @ the master cylinder.
Then you have only a few possibilities if only the RHF is troublesome.
Adjustment, sticking wheel cylinder, faulty flex hose @ RH steering knuckle.
When the problem is apparent releasing the brake bleeder will allow any pressure build up caused by a faulty flex hose to escape & the wheel should turn freely.
You don't need to be on the road just jack up the vehicle on the RHF & pump the pedal a few times....if the hose is faulty nothing needs to be hot to duplicate the fault which will be apparent with the wheel locking up or brakes dragging.

One needs a basic understanding of how system parts interact with one another. GOOD parts can then be systematically established & the NOT GOOD problem/s part/s isolated for repair or replacement.
