The past several times I engaged the Parking/Emergency Brake handle; on an incline the Jeep would move slowly until I applied the last click on the EB handle.
Today before I became TOO hot (projected to be >100* today) I chocked the front tires, jacked up the rear of the Jeep, placed the transmission in neutral and adjusted the BMB disc brake star adjuster two clicks then tested the tire drag/movement with the EB disengaged and engaged.
With the EB engaged; the tire would not move and with the EB disengaged I did not hear any drag.
Placed the Jeep back on the ground, placed transmission in reverse to remove chocks, set the EB, placed in neutral and tested the Jeep on an incline; no more moving slowly.
Connected gauges to the A/C and tested with outside temperature at 91*, added approximately 1-2 oz to trim the charge and the DAT is very nice.
I will need this cooler temperature later today with the projected >100* temperatures.
