Repeat this new duration up until ten decelerations were made
S5.4.2 Brake energy. Whenever attached with an enthusiastic inertia dynamometer, for every braking system would be able to make ten consecutive decelerations at the typical price of nine f.p.s.p.s. of 50 yards.p.h. so you’re able to 15 m.p.h., within equal durations regarding 72 seconds, and you can are going to be with the capacity of decelerating so you’re able to a stop out-of 20 yards.p.h. in the the common deceleration speed off fourteen f.p.s.p.s. one minute following tenth deceleration.
S5.cuatro.dos.1 With a primary brake temperature between 150 °F. and you may 200 °F. on basic brake app, and also the instrument or disk spinning at a rate equal to fifty meters.p.h., implement this new brake and you can slow down within an average deceleration speed away from 9 f.p.s.p.s. so you’re able to fifteen m.p.h. Up on interacting with fifteen yards.p.h., speed to 50 meters.p.h. and apply the fresh brake to possess the second go out 72 seconds after the start of the original software. The service range air tension should not go beyond a hundred psi through the one deceleration.
S5.4.2.dos The second adopting the stop of one’s past deceleration called for because of the S5.cuatro.2.step 1 along with the instrument or disk spinning in the a speeds off 20 m.p.h., decelerate so you can a stop at the average deceleration rate out-of fourteen f.p.s.p.s.
Particularly circuits can be enough to let the antilock program to your for each towed automobile is completely operable
S5.4.3 Brake data recovery. But because offered inside the S5.4.3(a) and (b), carrying out a couple times shortly after finishing brand new evaluating necessary for S5.cuatro.dos, a beneficial car’s brake should be capable of making 20 straight finishes from 30 miles per hour at the an average deceleration speed out-of twelve f.p.s.p.s., within equal intervals of one moment counted right away away from for each brake application.
