Who Uses the Parking Brake?

[MABachE131]

Does it disengage the brake when you shift out of Park or do you have to press the accelerator?

When shift out of park.

When shift out of park.

Do you have a setting for this?

No.

 

[generaltso]

No.

Well, I have no explanation for this behavior unless it’s unique to GTs. I’d enable it if it was an option.

Thanks for the feedback everybody, looks like I'm going back to using the parking brake at home (until I can clear the garage).

...and get'er out and drive more!

I have some of what you describe. When I park it in garage I’ve taken to not using parking brake as after a few days of no movement it will ‘catch’ and I feel like I have to accelerate to disengage it even when I disengage and engage the switch several times. Seems like just drive it more is a real workaround. Would expect a fix for 60K car but maybe I expect too much

My experience with regular ICE cars is that if it rains, either some rust can form on the brake rotors (if a long enough time), or dirt spatters onto the rotors/pads and it is getting ground off the first few times you brake when driving.

There's a parking brake? *ducks*
LOL

You all realize that the parking brake on a 4-wheel disc braked car is acrtually a small drum brake inside the center of the rear rotors, right?

...Our MME lives outside in our driveway, which is slightly angled / not flat. So when we put it into Park and let our foot off the brake, it rolls back a few inches (not unlike any other car, but it feels more exaggerated than our Subaru, for instance). So we started using the parking brake to reduce that (almost stops it completely). But after not being driven for four days with heavy rain, I went to move it from one side of the driveway to the other, it felt like the parking brake didn't disengage (grindy noises). Later I went to drive it and, when I pulled away, heard "shrrrk - shrrrk - shrrrk" noises that sped up as the car sped up. It quickly dissipated and, less than a mile down the road, was completely gone. I figured it had something to do with the parking brake "sticking" and never looked into it further. And since then, I've avoided using the parking brake and the issue has never come up again. Now we just live with that weird sensation of the car rolling back after putting it in Park and letting off the brake...

So I guess I should update this...the same symptoms happened again after I went back to using the parking brake. So I called the dealer and had them look at it. Of course the first problem was they couldn't replicate it, so they suggested I try to bring it in when I could leave the car overnight and they could park it on a similar slope and see what happens. Of course, we're going into summer now and likely won't be able to replicate the other element in all of this...overnight rain.

The tech did look for anything re: service bulletins, etc. and found nothing for our car. And of course they physically inspected the brakes and pads, etc. As far as they could tell, all was functioning normally. When I inquired about just leaving it in park (i.e. not using the parking brake...does that hurt the car) he kinda looked at me like an idiot...i.e. of course it's fine to just put it in Park and not bother with the brake.

So that's what I'm doing now. Maybe next Fall / Winter I'll see if I can leave it with them for an overnight service appt. But until then it's just more driving and enjoying.

...without using the parking brake...

Most newer cars I've had to deal with, that have electronicly activated parking brakes, have electric motors built into the rear calipers to push out the piston to apply the brakes. Less weight and simpler. Pretty sure thats the system the Mach-e uses but I can't remember and I can't check becuase my wife just stole it on me.

I use the parking brake every time. That’s what I was taught in school some 40+ years ago. And it is on the driver’s test in my state, and probably every state in the US that it should be used.

I had a similar experience with a rear brake locking up after applying the parking brake. It happened after thoroughly washing the bright red calipers and wheels then parking for a day inside the garage. I released the parking brake then tried backing up, but the car would not move. I added more electrons, and it released. However, as I drove I heard a repetitious sound from the right rear wheel area. I am assuming that I broke a small piece of the brake pad off which had welded onto the disc. After a mile or so the noise went away. (With my 1993 Explorer, I just used the volume control for strange noises.)

I took my Mach E in for the 10,000-mile service and told the service department about the stuck right rear brake. I found TSB21-2206 https://static.nhtsa.gov/odi/tsbs/2022/MC-10209201-0001.pdf and printed a copy and showed it to them. They ordered new pads for the rear brakes and machined the rotors. No cost for the repair.

I use the parking brake when parking in my garage since the space is tight. The Mach E tends to roll slightly if I just use park.

Thanks, I'll have to try them again with this TSB. When they checked, they couldn't find one for my car. So first trip with the service dept. is not giving me great confidence...

This should be a poll. I use it 100% when I am out. I do not use it when I park at home in my driveway. My garage queen gets the garage...
So out of my 4 cars, we all use the parking brake when not parking overnight or long term.
