Parking Brake unexpected Release (MT)

[zrk]

Hey! Everyone! We all agree. Leave it in gear. Lots of misreading and other confusion here.

Maybe reading comprehension has dropped sharply over there because it certainly looks to me like Toyota 100% agrees with me. I've circled the offending statement for you.

But keep taking screenshots of manuals without you know.. actually, reading for understanding.

?

LOL OK, this coming from the guy saying not to park in first but second instead. ?‍

There it is. Don't expect Toyota to change the car because of your bad habit! Putting a manual in reverse every time you park isn't right, I don't care how many manual cars you've driven.

First? Umm.. no. Second, sure.

Ok.. let me spell it out for you.. according to your image, like me, Toyota recommends leaving the car in gear "IF ON A HILL" implying that it should not be left so otherwise.

And my other comment about second is taken completely out of context.

You said you drop your gear to first when in a parking lot - I presume while looking for a park. As far as I am concerned, that's not a great way to drive a manual car. First should only be engaged if it absolutely needs to be and for almost all slow speed situations, second is more apt.

Reading comprehension is more than just sounding out the words.

Seriously.. "IF ON A HILL.." But anyway, you keep doing you.

So here's a pro tip: if you're on a hill and you park in second, your car is a lot more likely to roll than if you'd have used first or reverse instead.

I explained why I hold the clutch in: because my habit is normally to set the parking brake, kill the ignition, put in first or reverse (if not already there) and only then let the clutch out.

ok so I guess no one in this thread ever drove a manual with less than ideal drum brake setup aka failing aka you wouldn't bet your life on the PB or heavy trucks...

If the handbrake cable is/got loose (and you didn't get it fixed, just a wrench away) or drum in bad shape or you're on steep hills all the time or bald tires, you made a habit of leaving your vehicle in gear regardless of incline. Also, you'd use the PB as means to assist in hill stop and go traffic [like auto-hold]. This came as second nature to people born pretty much before the millennium. Shitty tires, someone crashing into your car, some pissy rain. Never one to trust, as mentioned in the plane example, one system..

Someone asked, well what'll you do, yes you'd keep a wheel chock. it ain't big. if you keep a full size tire, first aid kit, emergency triangle, you can keep a chock..

Honestly, I never thought about putting it on reverse. always on 1st gear.

Leaving in gear, does/did cause issues with idiot towing companies. For FW vehicle it didn't matter, but if Tow didn't know your car is RW, your car in gear, it grabs the rear tires, then you're F'ed. Many may not understand why you'd be towed, but in some metropolitan parts of the world, people park at every inch they can find, thinking it'll be alright because really the only other option is to park miles away or just leave the car in front of "don't park here" sign because they just need to run to the bank for 2 mins or grab a donut whatever. but in these places a tow truck or two would be making rounds and you'd be towed. Anyhow, only a rookie tow would make this mistake and many places now have, don't know it's name, but grabs both axles almost like a narrow forklift for each axle and tows in 12 seconds.

Also, I hate it, especially on AT, when you put it in park and the car would slide just a smidge, so I always use the PB e- or not. also the foot pedal brake....

Someone suggested e-PB should hold until you manually disengage it, well that's not ideal either. in AT, it auto disengages, but obviously when you give gas pedal a go.

So, MT should really work the same. Not with clutch, but by gas pedal input. well, scratch that. if you only wanted to rev, then it'd disengage.. well ok, in gear and gas pedal should do it. but then you'd also be pressing the clutch and brake and about to disengage both to drive away...
well, you can have clutch and brake engaged and in gear, yet be revving.. so. maybe there is no solution lol. just give the people a mechanical handbrake.
ok, well just put an option in iDrive menu.
Park Brake Disengage with -Clutch, -Gas Pedal, -All, -Never, - n seconds after Pressing X/Y/Z, -just read my mind damn it, I'm revving now, I'll decide to move when I want.

I have the MT and never had this issue, just to add to the statistics here; mine works as intended from factory, and never 'released' by itself. I actually hate that it WON'T disengage whilst pressing the brake pedal but only if the clutch is in, which I always found odd...

I actually switch the car off in neutral with the EPB off so it stays off, I can roll the car a few inches without cold starting in, and avoid the rear brakes seizing and flat spots (I don't drive it much).

BUT, after reading this insane post, from now on when parking in public car parks, I will start using 1st gear as well, to give the benefit of doubt. That's what my dad had taught me since I was a kid anyway.

I think electronics are sketchy on any car. Now add to the fact it’s an electronic parking brake, I’m not a fan. Manual or automatic. There are threads of oil sensor malfunctions, camera malfunctions, you name it. Just give me a damn handle to pull and a dipstick!

There’s a million engineers on this fourm. Can y’all make a car w/out all this crap? ?

Apply it, and then try to drive away as if you had forgotten to release it. Does it self-release then?

Perhaps a silly question and I assume the answer is, 'of course not!' - but is there is there anything wrong with putting the car into first when stopped and the engine is off and then leaving it that way? I have never had this issue in over 3,000 miles and parking on slight inclines once or twice at work per week. I think I'm just working on implicit memory at this point but I believe that I always stop, put the car in neutral, engage parking break, and turn the engine off. I suppose I'm lucky that the brake hasn't disengaged at any point and will now play it safe with the car in 1st but just wanted to check.

Of course not! Lol , but thats what’s actually recommended by most if not all manufacturers.

"Of course not!" - but if you want to get out of the vehicle while leaving it running, what do you do when you can't trust the electronic parking brake that seems to have a mind of its own?

that’s why I hate it! I turn the car on and it immediately dumps the parking brake.

Never to late to learn and you know people can be lucky for years until they aren't. My background is in aviation and engineering and it's just second nature in that world to not rely on one system of safety only especially when there are two readily and easily available. Same as aviation engineering where failsafe structures are the norm. In other words no singular load paths, always design critical structures and systems with multiple load paths and redundancies so a single failure doesn't result in a bad situation.
How silly would you feel if your manual car rolled away when unattended and simply having it parked in gear would have averted the catastrophe.

I learned to live by the rule that "one is none, and two is one" with many things. Never rely on a single potential failure point if a second option is easily available.

I also wanted to mention that when parking on an incline, after setting the parking brake, it's good practice to place the transmission in the opposite direction gear as the potential roll direction. Example, if parking nose-down, leave the transmission in REVERSE gear, and FIRST gear if you're nose-up. That way if the parking brake fails, the load path would be trying to turn the engine backwards, which needless to say, is much more difficult than the direction it's used to rotating in.
