DOES YOUR PRADO BRAKE PEDAL DO THIS?

Re: DOES YOUR PRADO BRAKE PEDAL DO THIS?

My 05 Prado does the same. Yesterday I pulled off the front and rear wheels to check the pads only to notice that they had more than 60% life on them. My mechanic did indicate that the pedal sinks to the floor.

I don't like the brakes and may try flushing out the break fluid to see if that makes a difference. I probably should get the master cylinder rubbers checked as well.

my 2005 GXL does exactly the same. Been trying to chase up a new master cylinder until I read this.

So its normal?

Stops the car fine. But if you keep your foot on the pedal with a bit of presure the pedal starts to sink!!!

Re: DOES YOUR PRADO BRAKE PEDAL DO THIS?

Hi all,

I have a 2008 GXL with stability feature built in and have not noticed this issue, I
don't think it has a master cylinder, I think it uses some form of electric pump.
Will check it out tomorrow though and see if I get the same result.

Aside from that, doesn't matter if Toyota say it's normal or not, the fact is, it is dangerous!
If for instance your on a slipper up hill or down surface and you have to pump the brake pedal
you could quite easily loose control of the vehicle and have a serious accident.

In the case of the pedal sinking straight to the floor and the resultant panic few would think to
pump the pedal, it may not work any and then again you may not have time to anyway.
You can bet if it happened when your wife is driving she not going to.

I would be returning to the dealers concerned and make sure they note what you have said on
the service record of your vehicle and also to note that the pedal gradually sinking to the floor is
normal. And make sure they give you a copy of it. I would then be sending a registered letter with
delivery confirmation (keep a copy for yourself) to Toyota listing your concerns and stating that if
you have an accident as a result of pedal fade you will hold them reponsible be taking legal action
against Toyota to recover damages.

Every driver expects to have brake pedal pressure when they hit the brake pedal 100% of the time
even one failure should be fully investigated by the manufacture to see what happened. The
fact that several of you have experienced the same issue indicates there is a design issue which
needs to be fully investigated.

I remember this sort of thing happening many moons ago due to the cups in the master cylinder
turning inside out. It should not happen with modern dual system units, you should at least
have the front or back brakes working, both systems should not fail at the same time.

Any of you that are members of road assist organisations should also be trying to see if
they can push the safety aspect for you.

Cheers
LeighW

Re: DOES YOUR PRADO BRAKE PEDAL DO THIS?

just an update.

My mate has 3 prados in his yard.

2 2005 models petrol
1 2009 Diesel model

all 3 and I say all 3. The pedal does sink!!! Exactly the same as my one.

Turn the engine on. Sit in the seat and give that pedal a firm push. Watch it sick slowly....

mine is the same and yes admit I've had a few nervous moments with heavy traffic normally when I have a safety space and some dimwit decides that is thier spot.

I find using one heavy brake application is better than "riding the brakes"I discussed this issue with my mechanic (brother & toyota trained) and he confirms with me the the movement is normal, compared to the folks 90's corolla which has a heavy but feelable foot brake whihc I do prefer

diesels also use a vacuam pump is ths fuctioning proprley ?

yes I'd like a upgrade of the rotors and I'm still convinced I have gas out from the disc pads, warranty still applies so can't do anything about it as yet

Yes well am afraid I have to join the growing list of pedal sinkers with my unbreakable 2006 Prado that has done only 94000k, I recently had my first set of pads replace,as well as having the discs machined, before this I was quite happy with everything, brakes were excellent,I had acceptable pedal like any normal vehicle, it certainly didn't sink to the floor like it does now.
I like others I have done it the hard way by going through the normal procedure's, like paying out a bucket of money to have a new master cylinder fitted only to find it didn't fix the problem...I like others have no confidence in the braking system, I find myself sitting at traffic lights nursing the pedal frighten to apply too much pressure, something has certainly changed with my Prado, it has become a dog to drive with this problem. Tomorrow I take it back to see what else can be done .....I am so glad I found this thread as I might be able to short cut the red tape a little (maybe)

Got to a point that my 2004 Prado had a similar problem. Brakes were getting deep. Bite was very weak. One of the usual mechanics I go to almost gave me a heart attack by saying that only the front brakes were biting, and rears weren't. Thankfully, bleeding the brakes quite extensively solved the problem.

Last week an email was sent off to Toyota re this problem, am still waiting for a reply

Interesting information guys.

My curiosity got the better of me today at work and I grabbed the keys to a '09 120 series Prado crew car.

Sure as hell, with the engine running, I pressed hard on the pedal ..........

and it went all the way to the ground.....

This vehicle does get flogged but, it is inspected regularly and it passes its mine site safety inspections.

I am now agreeing that this may just be normal for the prado brake pedals.... Maybe to do with the ABS?

I am also looking into a Recall on the Master Cylinders on certain 120 series cars....

I did find some info on this by searching Pradopoint.....

I am calling Toyota tomorrow.... Will keep you posted with what I find out

So what was the answer ?????

My brake pedal on my Prado does not do this. I have overhauled the brake system (rotors, pads and fluid) myself as a normal maintenance service. I've never let Toyota touch the car since they screwed up the first service. Being mechanically minded has its advantages.

just checked mine and when the car is switched on the pedal goes all the way to do floor. Sounds like it's the way it's supposed to be. If the air was present the pedal would gradually "grow" as you're pumping it. This only happens when car is switched on.

I've never tested emergency brakes on it, i'll give it a go and see what happens

[Morrie_1 Lurker Find all posts View Profile Close Morrie_1]

Well I just had the car back to Toyota and they claim there isn't a problem, that is the way they are supposed to be .... I explained to them that I have have owned the car from new and never had reason to complain in 94,000k, unfortunatley they didn't want to listen....so I will be taking this matter futher .....stay posted ...I am one upset little vegemite at the moment so stay posted things may get interesting
