Hi, we nearly had a bit of an issue with our new Prado. My suspicion is that it was caused through my lack of knowledge but wanted to confirm.

We have a reasonably steep driveway, I came home one evening, parked at the top of the driveway, put the car in first, handbrake on, went in for dinner.

My wife came out later that night to go shopping and asked where the car was? It had rolled down the drive stopping as the rear wheels had hit the road, no damage done.

I was taught to always leave the car in 1st or reverse and never rely on a handbrake, it seems this isn't enough. I did some testing and the car will 'bump backwards' slowly even when in first or reverse.

We had only just had the handbrake tightened, but frankly this hasn't had a big effect on its performance.

Can anyone tell me is this sort of behavior normal? Do we need to carry a set of chocks around with us as there are several hills in the area that would be equally steep to our driveway?

Thanks, Sean

Something is wrong somewhere....if you did put in gear when you left then the clutch whould have to go in before it would move

This is what I though, but it doesn't - It' 'Bumps backward' It's a 6 speed so I wonder if gearing vs compression is different??
I tested it - Drove up the driveway, turned engine off, in first handbrake on. After a few seconds the car would bump back slowly. I could have probably cranked the handbrake on harder but it would have been a battle.

Comes back to that old adage, Be safe not sorry, recently I spoke to a guy and he had the CEO of a school where my fiance work's toyota hilux ute/ Now this ute all week he had being parking the car and leaving in it drive and putting the handbrake on, now being an older guy, put on the handbrake as far as he possible could, about 8 notches, and jumping out, the ute proceeded thru a metal gate across the drive and took out the gate the front bar, front drivers guard, drivers door,rear passenger door and the drivers side tray! Testing it later the shear power of the motor over powered the rear drum brakes and this was on like 14 notches and i pulled that handbrake up as far as i could pull and counted them.

So thinking about it if you can park it on the flat to save expensive repair and insurance claims or have the chocks near by or lock the wheel over to the high side of your drive, then that way you save yourself lots of heart ache and dollars.

I am not saying you might be complaycent i was taught the same thing handbrake and either first or reverse. I agree that you did the right thiing.

I agree with Troll. Something definately wrong.

With a manual gearbox in first or reverse, you need to overcome the engine compression for the car to move.

However, better safe than sorry.
Put the handbrake on,
Place the manual shift in first or reverse, or the auto shift in park Turn the steering to full lock. On a downslope in suburbia, the direction should be towards the gutter, usually to the left.

If your still nervous, place a bloody big rock under one of the wheels. That should just about cover it.

Oh, and I have recently checked my handbrake out.
She is working extremely well in keeping me in check:-))

G'day Sean
I don't own a Prado but something's not right. You say it's new - is that new as in still under warranty? If so I suggest you take it back to the dealer for checking, otherwise take it to a mechanic. Being in gear and with the handbrake on it should hold - your driveway can't be that steep. I assume it was in high range. As an interim measure I suggest you put it in low range with handbrake on when it's parked on your driveway. If it still moves off then you have real problems.

Thanks, Yep it's under warranty and we are putting it in next week.
I just wanted to at least make sure that there was something wrong, so that I don't get fobed off.
I think I did try it in low range with the same resault, may have been a little slower to move. I might try it again.

I am an ex Prado owner and probably the previous model to what you have. Prados are notorious for having an ineffective handbrake. That said, I always thought the same as you. Put it 1st or Reverse as well as the handbrake on should be enough.

If I ever have trouble with my handbrake I simply swear at it and sometimes give it a bit of a thump and it seems to behave itself for a while. From my experience it seems to be normal behaviour for a handbrake to carry on and not do the things you would expect them to. Handbrakes - who needs 'em?

The handbrake in my new Prado is very ordinary. It will be the first thing I mention at the next service.

Hi All
I always have my foot on the brake pedal pressed in before I engage the hand brake.
Cheers

Hi Charlie, would this only work if your back brakes work for both hand brake and foot brake, where as the prado has an inner drum on the rear disc for the handbrake with seperate shoes and the foot brake puts pressure on the disc pads onto the discs there fore putting foot hard down on brake will not help the handbrake in any way ???. I think I can see what you mean cause when I had the old hilux when I put my foot on the brake then pulled the handbrake up it was easier to pull as the rear shoes were already applied by the pressure on the foot brake but the lux was rear drum and brake shoes were used for foot brake and handbrake ?? Not sure if this makes sense or not. Just wondering, as my handbrake in the prado works ok but definantly doesnt hold as well as the old lux did and everything has been checked and serviced but maybe Im luckier as mines auto so can lock into park well at least I hope so. I have tried with the foot down and doesnt seem to make any difference to how the handbrake holds. Will try again.Regards Steve M

Hi
Stephen M
Yes it would only work if both were as one. It is something I have always done. Have 005 prado 120 auto never had a problem with handbrake, just surmised they worked together. Will check but always left in park anyway.
Cheers
Charlie

Charlie,

Steve is right, the Prado has a separate drum brake inside the rear disc brake hub.

Prado's are well known for a weak hand brake.(120 series that is...not sure about the 90) You'll find most Toyota dealers adjust them every service.

Mick.

Yes, it’s a great car to drive. I'd be ecstatic if I could stop the thing rolling down my driveway.
