cuatro.dos Brake fuel. When attached to an inertia dynamometer, for each brake will be able to make 10 successive decelerations at the an average speed from 9 f.p.s.p.s. from fifty meters.p.h. to 15 meters.p.h., in the equivalent durations from 72 moments, and can be effective at decelerating in order to a halt from 20 yards.p.h. at the the typical deceleration speed of fourteen f.p.s.p.s. one-minute adopting the tenth deceleration.

4.dos.step 1 Which have an initial braking system heat between 150 °F. and you will two hundred °F. on the basic brake app, therefore the musical instrument otherwise disc spinning in the a performance comparable to fifty m.p.h., implement the newest braking system and decrease at the average deceleration rate away from nine f.p.s.p.s. to fifteen yards.p.h. Abreast of reaching fifteen meters.p.h., speed to fifty meters.p.h. thereby applying this new braking system to own the next big date 72 moments just after the start of the original app. Recite the fresh new cycle up until ten decelerations were made. The service range sky tension will perhaps not meet or exceed a hundred psi throughout the any deceleration.
This service membership range sky tension must receive a performance away from twelve f
4.dos.2 A moment following avoid of your own past deceleration requisite from the cuatro.2.step one along with the instrument or disk spinning on an increase out of 20 meters.p.h., impede to a stop on an average deceleration price out-of fourteen f.p.s.p.s.
4.3 Brake healing. Except due to the fact provided into the 4.3(a) and you will (b), creating two minutes just after doing new examination necessary for 4.dos, a beneficial vehicle’s brake might be capable of making 20 successive comes to an end away from 30 miles per hour on the average deceleration rates from several f.p.s.p.s., during the equal durations of just one second measured right away away from per brake software. Continue reading Brand new a number of decelerations are going to be used as follows:
