A braking arrangement adapted for use in connection with a rollable cart employed in commercial airplanes includes a longitudinal base plate, which has relatively narrow end portions of a predetermined width, and two roller pairs mounted on the base plate. At least one brake mechanism is mounted on the base plate, and acts on a corresponding roller pair. The brake mechanism includes a brake rod in parallel with an axle of the roller pair, a mounting plate for the brake rod located between the rollers, which has a recess on its lower side, and a rotary disc mounted within the recess of the mounting plate, which, in turn, has a downwardly projecting portion provided with two entrainment lugs. A guide for the brake rod is mounted on the mounting plate for restraining lateral movement of the brake rod, while permitting a movement of it along a substantially vertical direction. A brake pedal is connected to one entrainment lug downwardly actuatable within the width of one end portion of the base plate, and a brake-release pedal connected to the other entrainment lug is downwardly actuatable within the width of the other end portion of the base plate independently of the brake pedal.
