  • DOES YOUR PRADO BRAKE PEDAL DO THIS?

    Push with a very firm pressure on the brake pedal while the engine is running and the pedal slowly sinks to the floor almost.
    I must state that in day to day driving my vehicle stops ok and you do not normally notice it.

    After taking it twice back to the Toyota dealer they now tell me "THAT'S NORMAL in Prados". I would leave until they let me try some other Prado's................... DAM'N THEY DID IT ALSO!!!!!!

    ANYONE ELSE have a similar problem?

    You may say well I will never push my brakes that hard. Well believe me I have when doing some rock crawling on a steep descent. You will really need to lean on that pedal as you are easing over the rocks. The brake pedal slowly goes down to a stage you have trouble almost reaching it and you start to panic that you are about to lose all braking.

    Pete,

    I've noticed that the pedal feel in my 120 is not what I'm used to.

    See: http://www.pradopoint.com/viewtopic.php?p=471#471

    I think it might have something to do with the EBA (Emergency Brake Assist) function.

    I think I remember my Subaru Forester doing it once when off road also.

    Someone with more mechanics knowledge might be able to explain it further.

      Thanks for the post John, Drew

      I thought I was heading for a fast trip to Toyota. I too noticed my 07 - 120 brakes appeared to fade. Sitting in the driveway with the motor running I noticed the brake pedal fading towards the floor - Not something I expected. Seems OK on the road. Nice if Toyota put a warning in the manual (Ops, maybe I should check). :?

      Cheers

        Roger that. It is normal. Cruisers do it as well.
        Feels a bit funny i know. also just after start up you can hear the cylinder "pumping " up.

        tis all good

          Prado Brakes (120 Series)

          I purchased my Prado D4D in Feb 07 and found the pedal went to the floor whilst in traffic. Apparently normal for Prado's. At the 10,000 kms & 20,000 kms service my brakes were checked by the Dealer and found to be operating efficiently. Three days before the 20,000 kms service I had a minor accident where the Prado did not pull up. The pedal went to the floor. I complained and was advised that a full bleed of the system was carried out and no problem could be found. After about four days, I again had a narrow miss in traffic and was not happy :cry: . I located a Brake specialist who bleed the system and found air in the lines. Further tests found that the Master Cylinder was faulty. I went to the Dealer who was livid that I had taken the Prado to an outside specialist. I changed Dealers and had the master cylinder replaced under warranty and have had no problems since. The pedal still travels further than what I have been used too, but the Prado pulls up now.

          If your problems still persist it may be best to seek a second opinion.

          I followed your suggestion and sought other opinions. A 2nd master cylinder was replaced by another Toyota Dealer as they thought the vehicle was unsafe. An inspection centre mechanic had the opportunity to drive this car and stated that the brakes were inconsistent and advised that the ABS was not operating correctly. When a dealership was approached they stated they the brakes were fine. Prior to the expiry of the warranty I had a full mechanical inspection and as a result of this inspection had the CV boots replaced, and turbo replaced. After 96,000 kms the disc pads still had 80% on the front and 65% the rears. The mechanic was aware that we had towed a caravan around Australia and approx 40,000 kms of the 96,000 km had been with the caravan on the back. He felt the brakes needed an overhaul. I approached the dealer but the received the same reply.

          For us the problem has now been solved. We traded it in on a 150 Series Prado GX, 5 door, 5 seater. We have now got 360 kms on the clock and no problems. Touch wood. This will be the last Toyota for us if we have anywhere near the problems with had with the 120 series.

            I haven't noticed the poor pedal feel yet but I've had a few funny things happen with the ABS at low speed.

            Today I was driving out of our driveway (very slowly) and a car was coming so I braked to stop and the car kept creeping forward and you could feel the ABS doing something weird. The missus even got a bit edgy because she thought I didn't see the car coming!

              The ABS is a little strange in my Prado as well, coming out of the same shopping center 2 times when it is wet the ABS has activated at low speed.

                hey guys... interesting posts....
                My 120 series brake pedal goes to the ground if I hold it down hard enough as well
                In everyday driving it seems absolutely fine..
                Maybe an independant opinion may be needed on this one!
                Off to a brake specialist i go...

                  Good luck Mackayvx. I had two brake master cylinders replaced and countless near misses before I gave the Prado back to Toyota and bought a 150 Series. In the end Toyota Technicians didn't reply to any emails because the dealers said there was not a problem with the brakes.

                    Re: DOES YOUR PRADO BRAKE PEDAL DO THIS?

                    A couple of years ago in my 03 model, I was towing my 5mtr boat down into Wisemans Ferry NSW when the brake pedal went all the way to the floor. No brakes at all! I could feel my freckle gripping the seat! For those that know the area ... I shot around the last bend near the pub, turned hard left, and shot through a line of vehicles getting on the ferry. I pulled up on the handbrake about 10mts down the road. Talk about shi#@%ing myself!
                    I also took it to my dealer, who after 3 days in the workshop, said that they could find no problem with the braking system but they replaced the master cylinder anyway. It never happened again but I always expected it to, and the brakes continued to feel soft. The brakes never felt great on the 03 model and it's the same on my new 09 model. I would be interested to hear from those who have changed to the larger vented after market disks to see if it improved them at all. I think the heat effects the standard system greatly.

                      Re: DOES YOUR PRADO BRAKE PEDAL DO THIS?

                      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

                        Re: DOES YOUR PRADO BRAKE PEDAL DO THIS?

                        I was too, curious about my 120 series Prado brakes doing the same thing.

                        The brakes were fine until the day I drove it on flooded streets. I know that sounds normal for a Prado but the thing is I was doing around 60 Kph on 100 cm of water and when the road cleared out I tried to slow down but the pedal just went through the floor without the Prado even stopping at all. This was around 2 years ago, I tried the mechanics but they couldn't give me a correct feedback. I do have brakes but not as good as how they were before the rain.
                        Suggestions?

                        Thanks!

                          YES

                          But I have short legs so I have to slide off the seat to stop it :shock:

                          No joke :!: It does happen sometimes at low revs

                            There was a recall on the Prado 120 series for a master cylinder check. There was a weaping shaft seal in the booster and replaced under warranty if leaking.
                            They pulled them apart for inspection and if one drop of fluid visible, the units were replaced.
                            Mine was done and took 3 days for the parts to arrive and be replaced.
                            Have noticed that the pedal is no where near as solid prior to booster replacement, but no fading or failures, as yet..

                              Hi All,

                              Interesting Topic.

                              I am having the same problem with my 08 D4D Prado, which has done 72K
                              The brake pedal sinks slowly to the floor while at a set of lights or on a hill.
                              I did have a near accident when the brakes seem to have failed, as it nearly didn't stop me.

                              I have done a 4WD Course and drove through a River as part of that course several times, and got caught in the floods around Ballarat, back in Feb /March.
                              I have had Toyota Bleed the brake fluid twice and checked the Discs and they have advised all is ok.

                              So it looks like a trip to the Brake Specialist and also a call to my Toyota Dealer as I am not happy with the why its braking.
