Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / April 2008Lincoln LS Parking Brake - Principle?
My curious mind just wants to know.... I recently aquired a 2004 LS and it's the first car I've ever owned where the parking brake wasn't applied "mechanically" through pulling on a lever pivoted near the floor or pulled out from under the dash or stepped on with my left foot. What's the operating mechanism which responds to the finger operated parking brake switch located on the console? Is it as foolproof as the older style mechanically operated "emergency brakes"? Thanks guys, Jeff  SignatureJeffry Wisnia (W1BSV + Brass Rat '57 EE) The speed of light is 1.98*10^14 fathoms per fortnight. > My curious mind just wants to know.... > [quoted text clipped - 16 lines] > (W1BSV + Brass Rat '57 EE) > The speed of light is 1.98*10^14 fathoms per fortnight. I would imagine it operates on the same principle as the push button transfer cases for folks who can't move a transfer case lever, nothing more than a gear motor and position encoder to do the work. > My curious mind just wants to know.... > [quoted text clipped - 5 lines] > What's the operating mechanism which responds to the finger operated > parking brake switch located on the console? The actual brake mechism is the same as you are used to, but instead of being operated by a cable, it is operated by an electric motor. The 2002-2005 Ford Thunderbird shared the actual rear brakes with the LS, except they used a traditional cable to operated the parking brakes instead of an electric motor. > Is it as foolproof as the older style mechanically operated > "emergency brakes"? No, not in my opinion. But it probably works OK.

Of course sine few people these days know how to do that it probably doesn't matter.
