Who's truck has a parking brake, who has an emergency break?

[d3500ram]

LOL...

When I was in tech school years ago, I had an instructor that would dock our grade on the lab work if we ever called it an emergency brake (because there is no such thing in his mind.) To him, an emergency break was what a student would take when they were about to piss thier pants...LOL :B

Not necessarily true. My off-road (but "street legal") rig has a home-brew disk brake setup in the rear with no parking brake. So I use a line lock as a short-term "parking brake". Normally, though, parking in gear is sufficient to keep it from rolling away.

My off-road (but "street legal") Samurai has a home-brew disk brake setup in the rear which includes the parking brake with the OEM hand lever. I have no line lock.

I should have been more detailed. A line lock cannot be used to replace a Parking brake. The reason being that if the hydraulic brakes fail, you can stop using the parking brake. I can't provide a source for this, but it is a major concern when converting drum brakes to disc.

... brake line locks illegal in california? ...

This beast has a line lock:

The 2018 Dodge Challenger SRT Demon is an absolute beast

Emergency Break = Automatic
Parking Break = Standard

IMO

The first thing you learn with either is not to use it in freezing temps unless you don't want to go any where till they thaw out.

When I was a teenager we used to call it a "U brake"! Get rolling about 30-ish, hit the "U brake" and crank the steering wheel - instant U turn!

The Mechanical brake that is installed on our Motor Home doesn't really seem to be anything but that. I really don't think it would stop the rig, and I certainly would'n depend on it to park on an extreme slope. It is connected behind the transmission on the drive shaft, and not to any of the actual wheel brakes.

That parking brake should hold the RV parked in almost all conditions. I recommend shifting to neutral, set the parking brake and see that it holds before you place it in park. If it does not hold then have it serviced. Same goes for all vehicles.

Mine has both

a park brake on the left side and an emergency brake next to the accelerator pedal

I don't think it's so much that they're illegal as that they don't qualify as a parking brake. To be legal, a parking brake needs to be independent of the service brake system, which a line lock is not. If you were to blow a hydraulic line, for example, a line lock wouldn't help.

There are some disk brake systems that use the same calipers with a mechanical actuator, and there are air-braked vehicles with spring brakes that share the same foundation brakes, and they're obviously legal. So I don't know exactly what the law says, but that's the basics of it.

If you want to look it up, it should all be in the Federal Motor Vehicle Safety Standards.

Illegal?
I guess no Camaros for you then 🙂

Just because speeding is illegal doesn't mean that nobody speeds. Maybe not in California because you have a hard enough time getting up to the speed limit, let alone exceeding it, but if you've ever been outside California, you'd know what I mean...

The term "emergency brake" and "parking brake" are used interchangeably in the US. In the Midwest, most are frozen in the off position within 2-3 years because the are never used.

Parking brake = what modern cars today have as standard equipment.
Emergency break = needing to use the restroom very soon.
Emergency brake = an ancient device used on early automobiles.

Flintstone brake = a device used on cartoon vehicles without shoes (not to be confused with break shoes...LOL
