Vehicles without integral braking systems are required to be chocked when parked on an airfield.
mechanical and hydraulic are two different power transmission medium. in mechanical brakes solid links or levers are used to achieve the required braking. in hydraulic brakes there are no links, here the braking is achieved by the hydraulic fluid, the hydraulic system in which the force applied at the brake pedal is multiplied several times to achieve the requied braking.
Vehicles that do not have an integral braking system are required to be chocked when parked on the flight line.
I'll give a nice simple answer here. Braking efficiency is used to describe how effective your vehicle's braking system is at reducing your vehicles speed as needed and halting it when required. I would use the term as follows - Towing a trailer that is too large for your vehicle to tow will severely compromise your vehicles braking efficiency making it very difficult and/or impossible to reduce your speed when required.

There are as yet no plans to send a manned mission to Mars. It is likely that parachute braking will be employed in addition to retrorockets to facilitate any landing.
Three different letters.
The brakes will remain on, air pressure is required to release the brakes
