Downshifting is always good for slowing, but not much good for stopping. The two-speed Powerflite3 in our ?55 300 will certainly slow you down when the ?dagger-on-the-dash? is dropped into low?if you have time. Old Buicks with Dynaflows had the reverse position in the lowest position of the selector lever. A friend said his kid reached over and yanked the selector down while he was driving and the old Buick flat stopped. I?d heard similar other stories about Dynaflows. Moving the gear selection to the left hand pillar of the ?56 Chryslers kept the passengers out of the driving game. There has been lots of healthy and respectful chatter on the old problem of stopping a moving vehicle. And, it is interesting to note that the very ?highest? technology in current cars can have the same basic problem when computers take over throttling, braking and so many other tasks. That said, braking systems have been evolving for years and are responsible for a good portion of the reduction in the highway death rate. Chrysler, of course, was an early leader in the use of hydraulic brakes across the line and the wide use of disc brakes on Imperials was also early on the scene. I think I read where they were installed on the racing hemi Saratoga's of the early '50's, including "Adam"--the predecessor of the 300. Regretfully, Chrysler did not follow through with these on the early 300's. But the early 300's could be converted to Imperial brakes as I understand it. Anyone heard or experienced how those old disc-brake Imperials stopped? No one has mentioned the old problem of a ?road pop? can or other junk rolling out from under the front seat and lodging itself under the brake pedal. I expect this thread will encourage some to review the braking systems on their 300's and take any actions to preserve car and carcass. Moving "road pop" cans, flashlights, Kleenex boxes, gloves, rags and tools out from under the front seat is a recommended action.

Strikes me that downshifting the car into first or second would have a better effect than having it in reverse with an automatic kick out into neutral.

He would gently push the reverse button to engage the back-up lights. Worked like a charm. The transmission has a safety default in that pushing the reverse button when in drive at speeds 15 mph or greater will move the manual control lever to the neutral position and when the vehicle drops to less than 15 mph it will be necessary to reposition the R button.

Suppose your brakes went out and all you now had was your parking brake to save you from certain mayhem. Would you pull the brake just a little to slow down gradually and risk having it fade and become useless? Or would you pull it decisively so as to lock it up before it has a chance to fade from overheat? Would pulling it too hard at speed bust up the brake and leave you with nothing? >>> I seem to remember that the California Hi-way patrol tested cars every year for suitability for use by them. Mopars failed the "Emergency stop" test regularly. I remember photos of the Driveshaft being snapped off, either leaving the car with nothing or actually dropping to the road and causing more problems. I also think that this was the reason Mopar went to standard rear drum emergency brakes, loss of sales of fleet cars. I think there is a Hot Rod mag article on this test. Or how about hitting the "R" button at road speed? Is there a lockout to keep it from going to reverse at certain speeds? That maneuver may possibly throw your car in a spin, but prudently done it might be better than coasting a half mile looking for a soft tree to stop you. >>> Won't work. My buddy had a new '57 Fury and he would push the "R" button if someone was too close. He also did this once at over 100 with some Bad Bikers chasing us and they faded fast when those back-up lights came on!
