That's the big brake pedal.

I wonder why when you grab that handle on the floor console or between bucket seats and pull on it real hard and the car's rear wheels lock for a moment, then the car spins 180 degrees they call it an "E-brake turn".....................just saying Maybe before the 1966 Federal Motor Vehicle Safety Standards (FMVSS) and the dual chamber master cylinders it was sometimes termed and actually used as an "emergency" brake/braking method but not today. A lot of this is now the Kleenex vs tissue, Xerox vs photo copy, "dialing" a phone number vs pushing buttons to call someone, and a hundred other "genericizations". At one time it was on some vehicles an "emergency" and parking brake but there ain't no way (yep ain't and a double negative ) that cable device is going to stop a vehicle, maybe it will slow it down like a fly on an elephants butt would create wind resistance

From Wiki and "Parking Brake" : The parking brake in most vehicles is still completely mechanical. Traditionally engaged by pulling a lever, the cables manually engage part of the car's braking system, usually the rear disk or drum brakes.[12] The mechanical nature allows the driver to apply the brake even if the main hydraulic brake system fails.[7] Good luck with that

I am not used to the term service brake either.

On a couple of the bigger trucks I have driven they had a brake button on the dash. I didn't drive a lot of bigger trucks so I am not sure what it was called but you set it when you parked.

While in high school I had a Mustang II. The pull handle between the seats identified as a drift enabling lever.

I also had a 66 Charger pop a wheel cylinder. While going down a slight incline the brake pedal decided to identify as an accelerator.

YES, happened on two separate vehicles, my 64 4 speed plymouth and a 62 dodge auto. Now both times I was going 30 mph and getting ready to make turn, both times the rear rubber line to axel broke. A little understanding here, with drums in the back the cable acts the same as pushing the brake pedal (it has a LONG arm for better leverage force). When disc brakes are used there’s a tiny set of shoes inside the disc, real good for holding a vehicle at rest, not to good for emergency situations. The mechanic next door just replaced the complete assembly on 2001 Dodge mini van where the guys daughter left the emergency brake on. Only one side was engaged, she said she had to keep the gas pedal flooded to get back home, NO CLUE what the problem was. Fried the drum, burnt the linings off the shoes, smoked the wheel cylinder and warped the backing plate. She did add it got easier to get up some speed after awhile (linings gone).
BUT even in the new cars your ‘parking brake’ WILL STOP YOUR CAR IN AN EMERGENCY.
One more thing, not sure of back in the day if the car companies were lawyered up like today for lawsuits but saying it’s a parking brake let’s them off the hook if said device were used in an ‘emergency’ situation that didn’t end well. It’s all about correct ‘wording’

I have never heard of a brake pedal being called a "service brake"

If you refer to my first two posts, using the "SERVICE BRAKE" in conjunction with the "PARKING/EMERGENCY brake" was one of the suggestions I made. Might not have worked so well with the detached cable But it is something I has done for years especially with a stick trans on a steep grade
Glad you got it sorted and thanks for the update

Way to go Guitar, start a huge fight on Moparts with riots likely to follow, and all over the parkmergency brake.

That's Emergencypark break (yeah "break" is deliberate )

Well I’ve heard some good arguments before but this one isn’t one of them. The hand brake/E brake park brake what ever you decide to call it of all of them the hand brake was the fist braking system used on a vehicle. When the hydraulic brakes came along the hand brake was left to use as an emergency brake if the hydraulic brakes failed.

I wonder how many will read this?

I don't plan on it but "fist braking" sounds painful

Service brakes is the term the factory uses to describe the main braking system, in other words, the big brake pedal. Just funnin' with ya.
The cable that came off was for the self adjuster mechanism, had no effect on the operation of either (service or parking) brake operation.

I know right?

he's (maybe she's. or "it's") the same on every forum they post on. my post was to illustrate the fact, for the rest of the people in the thread, the facts on the emergency brake, as posted by an insurance company.

Yes, gloss right over the fact that your insurance company quote, lol, contains a glaring and factually incorrect claim that it reduces engine wear in the very first paragraph. You uncritically accept it because it supports your equally incorrect opinion of how the parking brake system functions.

And you obviously have no clue how an emergency system works.

Parking brake or emergency brake??? Me, I think parking brake because it always took the Lone Ranger and Tonto to stop this when it was a runaway, especially with all of that horsepower. That little hand parking brake was not going to do anything, and I never saw it stop it when I was a kid so I knew not to count on it when I got my Road Runner in 1969. back to:

Save the arguments for the important stuff, like proper pinion angle.

Yea what he said
