Emergency Brakes

Discussion in 'Off Topic [BG]' started by gottawalk, Nov 2, 2005.


  1. Why is it that an emergency brake will keep a car from moving forward real good, but not as well backwards?

    First of all, it's a parking brake. Not an Emergency Brake. If you rely on it in an emergency, you may find yourself sorely dissapointed. Second, usuallly, it only brakes the rear wheels. Third, in most designs, they will apply the same braking force going forwards or backwards.
     
  4. I often see the term parking and emergency brake used interchangeably. I was of the understanding that the purpose of this brake was two-fold, as a parking brake and as a means of stopping if there was a total failure of the hydraulic brakes (hence it is a mechanical brake).

    I usually use it when I am speeding and see a Constable of
    the Law. Then I pull the handbrake so I am not seen
    slamming the brakes on while I am going by at a higher than
    legal rate of speed and unduly awakening him or her from
    whatever porn he or she is surfing on the cockpit computer of
    his or her cruiser with my rear brake lights.

    This usually gets a scathing remark from my spouse, whose
    confidence in my driving skills somehow does not meet my
    own high opinion. The big CLUNK she hears when I do this
    does not reinforce her already low opinion of me for
    endangering her life and limb in this juvenile and
    irresponsible way. Additional remarks then fly from the back
    seat 'peanut gallery' to reinforce my already sadly threatened
    machismo and add to her unnecessarily dim view of my
    actions.


    I know, flame away. :p

    I ram into those waterfilled trashcans. That usually curtails any suspicions.

    Your e-brake needs repair, that's why.

    What if its located by the pedals?
     
  14. Then its a much less usefull foot pedal.

    I hate parking brakes. All cars need real emergency brakes. My parking brake wouldn't stop a shoping car propelled by the wind.

  16. First of all, it's either/or. Go to Howstuffworks on the internet and this diagram clearly calls it an "Emergency Brake"
    http://auto.howstuffworks.com/brake.htm
    Obviously, since it's not part of the hydraulic system, it's to be used both to park, and also in the unlikely event of an "emergency" when the hydraulics fail. :eek:

    Second, (and I may be incorrect about this...), the reason you can go into quite a skid if you pull on the "P"/"E" brake, is because it locks up all 4 wheels. I'll look into that one. ;)

    Third, "most", doesn't cover all, and I have yet to have a vehicle have the same "staying" power facing up a hill with the brake applied, than facing down the hill with the same amount of force applied to the brake. That's why I'm asking... :confused:

    Thanks for the input. Got me thinking..

    Wrong, IME the parking/E brake only applies to the rear wheels, and they lock up quite easily.

    If going about 80mph and you pull it too hard, the release button can be VERY hard to get to disengage when spinning down the road in panic mode.

    Not that I would know.

    :bag:
     
  18. COL (Chuckle out loud...) I stand, (or sit...) corrected. Maybe that aspect was before disc brakes... :(

    That "release button" problem sort of makes for a good reason to bring back the foot applied "P/E" brake. Just pull the lever to disengage! Thanks for the info.

    Yeah, I thought about the 4 wheel disc brakes and how that would work, so I added the IME. The cars I've owned with 4 wheel disc never got a high speed "test" since I was grown up and valued my life a little more lol.

    PS, reaching under a dash to pull a release isn't any easier....while the car is spinning down the road while in panic mode. Again, not that I would know. :D
     
  20. Actually, I found it quite easy, once centrifugal force positioned me under the dash with my face pressed up against the......

    Uh,...forget I said anything... :bag:
