parking brake on MDX

I have noticed the parking brake on my MDX to be very insufficient. Most of the time, when I park the car on a slight slanted road, and then put the car in P and put on the parking brake, the car will still move a little bit. So it looks like the parking brake isn't doing the job at all and the car is simply locked by the transmission. Usually it's not really a problem. However, sometimes I do launch a boat using my MDX. Even on a not-so-steep launch ramp, the parking brake can't really hold the car still and I would never leave my foot off the regular brake unless I have shifted the gear to P. Now here comes the problem. When I want to move the car again (upramp), since the car was locked by the transmission, as I shift out of P to D, I can feel the car shake as the gear moves. That doesn't sound good to the transmission. I think the sole problem is the weakness of the parking brake. I'm sure the parking brake works, but it just has so little holding power. Is it because the car is heavy? Is that a common problem, or is it just my car's problem? For example, if you stop your car on a not-so-steep road, put the gear to N, and put on the parking brake, would the car not move? I expect that to be the case (since it's like that for my other cars). Any suggestion?

I have not used my parking break but I will and see what happens with mine.

However I have noticed that if I am on a steep hill, in drive, and let my foot off the pedal, I roll back until I push the gas, like driving a stick shift. I do not like that! It only happens on steep hills, but I still don't think it should happen at all... first vehicle I have had that has ever done it :eek:

Completely normal, all of ours do this.

I know it is "normal" for Mdx, and possibly all Acuras, but this is the first vehicle I have that ever did this and I am not a fan of it, thats all :4:

If the vehicle is on a steep hill and it holds its position without accelerator input, or putting your foot on the brake, then the idle is probably set too high. Will it move on level ground with your feel off of the brake and accelerator?

I notice the same parking brake weakness on my Mazda Protege.

As for the hard shake to get to D, here is my solution for shifting to D or R after parking on inclines:
  • Press the regular brake.
  • Shift to N.
  • Depress the brake a little to let the car moves a little bit.
  • Press the Brake again.
  • Shift to D or R.

eRaul, I don't quite understand your suggestion. I get the hard shake (after parking on steep ramp) whenever I shift out of P (whether to D, R, or N). So stopping at N for a while and releasing the brake slightly doesn't really help.

carguy1234, I know your method should protect the tranny. However, my problem is if the parking brake is not strong enough, then the car still moves a bit when you shift to P. Then ultimately the tranny is still doing the job to lock the car.

May be the wire on my parking brake needs to be adjusted?

Sounds like you need an andustment. My parking brake will hold the MDX, though I've never pulled a boat so I can't say what would happen with that much extra weight.

I was trying to describe the reverse of what carguy1234 described.
Basically, put the car in N while pressing regular brake before applying or releasing P-Brake.

First off read your manual. It addresses this same issue. When parking on a incline up or down. First put your foot on the brake pedal, put your X in "Netural", step down on the emergency brake pedal, then put your X in P. THIS AVOIDS THE CLASSIC "BOOM" WHEN YOU release it into R or what ever.....
Hope this helps !

When it was new, my parking brake refused to hold the vehicle on my driveway too. Then I figured the trick is to keep stepping until it clicked about a dozen times and then it works great!! ie. gotta step on it like how we wanna choke someone:D You guys tried this?? (the dozen click thing... not choke someone... today is Sunday:))

Greetings from Muzaffrabad, we are on redeployment from Okinawa, to assist in the Earthquake relief effort, it's been so long since I drove the X that I have forgotten how poor the park'n brakes are, but we love our X so we adopt and come up with effective ways to manage our pride and joy. Thanks for the memories, I should be home for X-Mas.

Does that boom hurt anything ? What exactly is happening to cause that petrifying sound ?

BTW, I had the parking brake adjusted too but to no avail. It wont hold it even on my driveway.
Yes, it can and does hurt something--the transmission. Seems like a lot of people need a refresher in how to use a parking brake with an automatic.

The concept of using a parking brake with an automatic is simple--when parking on a hill you want the parking brake to hold the weight of the vehicle, not the transmission pawl. The transmission is not designed to hold this kind of weight. To properly use the brake, you should do the following:

1. Park the vehicle on the hill/slope as needed and keep your foot on the regular brake
2. If the vehicle is nose up, the vehicle should be in drive; if the vehicle is nose down, the vehicle should be in reverse
3. While it is still in drive or reverse, set the parking brake
4. Release the foot brake. You will feel the vehicle's weight "load" the parking brake.
5. Once any motion has stopped (and it should only be slight motion or the parking brake needs adjustment), put the vehicle in Park. There will be no clunking or additional movement when you shift into park.

This is the correct way to use a parking brake. When you are ready to drive away, you just about reverse the procedure:

1. Put your foot on the regular brake
2. Put vehicle in gear
3. Release parking brake

You will not get any clunking nor have difficulty shifting into gear.

Your transmission will thank you for it. :D

This classic "BOOM" is happening on my new Acura 2006 MDX.
I have a steep incline in my driveway. One thing I tried and seems to work is do as follows:
1. Engage the regular brake, shift x to P
2. Press the parking brake pedal and while keeping pressed, release the regular brake.
3. Release the foot of the parking brake pedal.
