      Well the answer was ............the pedal seemed a little softer than normal ......after a few tests they deemed the brakes to be safe. It was normal for them to sink when stopped ..............I guess I have to live with that however I have one more thing to go and thats have genuine pads fitted, unfortunately it was fitted with non genuine pads when it was last serviced.....I may not make a difference but worth a try.................over to you guys I have had my fill of this

        I have seen a test on a Navara that had similar problem. Pedal goes to the floor when not moving, replaced master - no change so the brake joint did a line pressure test on the system and found that as the pedal crept to the floor the line pressure kept climbing indicating that there was no leak causing the issue. A pressure test on the Prado may answer some questions.

        This doesn't explain the problems with the brakes failing completely though

            The pedal on my 2003 Grande is getting worse. At first I thought I was just imagining it. Now the pedal car will slowly start to creep forward at a stop. I press down a bit more and you can feel the pedal begin to sink and it will begin to creep forward again. This continues until the pedal is almost on the floor.

            I took it to a mechanic and he said it was the master cylinder. He priced a new one $3000 for my Grande ($700 for the GXL) Big price difference. When he looked for other options he found nothing. No after market ones. Re sleeving was also not an option because the master cylinder unit is a sealed item.

            $3000 for a master cylinder. Are you kidding? And from what I'm reading here it might not even solve the problem.

            Any suggestions that don't include selling the car?

              I've never liked the "lack of" brake pedal feel in the 120 from new. It never inspires confidence, period.

              I'll take our old Volvo where your head almost hits the windscreen if you hover your foot over the pedal or my 1969 Mini with non boosted disc brakes over this any day or even our old Defender.

                My Grande just went on sale yesterday. Shame because it is a quality vehicle otherwise. But there is no way I'm spending over $3000 for a simple master cylinder. I'll go for a GXL or base model next time where the M Cylinder is around 700. Or god forbid, check out some other brands.

                  Update. Pedal became progressively worse before I could sell the car. Had a specialist look at it and gave me two options.
                  1. Replace with new unit $3238.00 installed.
                  2.Send to Melbourne and have the cylinder reconditioned $1600.00

                  I opted for the recondition, but after a week I was told they were unable to 'get to' the parts that needed repair. So I had the new unit installed for $3238.

                  Brakes are perfect now. Bank account looks like shit.

                  Lesson...Get a GXL next time.

                    its normal in most vehicles if you push the pedal while its running, not moving, it will go down a long way.

                    Then drive and push it to the same amount, you should go throught the windscreen.

                    Depending how bad it is you could have a problem and have a brake specialist look at it.

                    If Toyo say its normal, well they should know.

                      hi all, may not be much use , but depending on who's reading, i run a 2005 gxl, manual, and i recall that when the prado was new too me ,, i used too spend alot time playing,,, listening,, etc
                      one night i was in my drive , engine was hot etc, and i climbed in and started too get a feel for the pedal ,,,,,, but too my surprise it did the same and seemed to fade to the floor... being human.
                      i did the same pumped it up and tried again and again ,, but each time the fade was less, but i only have a.b.s , on the gxl... (6 speed manual)

                      i checked everything from that day on , and never once have i felt the prado brakes unsettling , the abs works nice on the tight dirt corners and all is sweet on the road... and it has never used a single drop of brake fluid, hot or cold,,,
                      the rotors are goin quite well till this day and the pads are acccordingly showing the 130,k from front to back but still nice and chunky for another 20 ,k easy... ... after reading more into it previously i put my worries into other area's that need addressing than the brakes, but dont get me wrong , mine has never faulted underway or it would be a different mattter, interesting read ,,, cheers butane

                        My second post. Prado 120 brake pedal fade. I was told by a dealer - they're all like that. Maybe they are, and maybe the reason is, that all of the original master cylinders were poor quality. If the brake pedal fades to the floor it's dead dangerous. Brake pedal fixed. I replaced the master cylinder with a Bosch, part number F06 A09 523 BMC-A9523, cost $210. This is what the servo looks like with the master cylinder removed. The original master cylinder was in the servo tight and difficult to remove. The pushrod is way back inside the servo. The servo opening was cleaned up with some silicon grease before the new master cylinder was installed. With the master cylinder replaced the brake pedal is firm, and with little pedal movement the brakes operate. While I was at it I replaced the front rotors with DBA slotted 47200S $429.60 and front pads Bendix Ultimate 1482ULT $114.40. I replaced the rear rotors with DBA slotted 4793S $387.20 and rear pads Bendix Ultimate DB1200ULT $107. Calipers cleaned up with a wire brush, brake cleaner, and then spray painted. The guides for the brake pads were removed and cleaned up thoroughly and lubricated with copper grease so that the pads slide on the guides. Lightly smear the wheel hubs with copper grease and wipe surplus off. When fitting the new rotors, put the wheel nuts on and tighten to get the rotor to sit firm against the hub and to precisely line up on the hub. Then remove the wheel nuts ready for fitment of the wheels. There are details elsewhere how to push caliper pistons back, take out surplus brake fluid from a master cylinder reservoir and bleed the brakes (I used a new battery hydrometer from Supercheap with the float inside removed and the ends of it taped up to drain the reservoir). One person can do it. The trick is to put some used brake fluid in the bottom of the container that you collect the fluid in. I used a 2 litre square orange juice container (Coles clear plastic), drilled a hole in the cap for the tube as a snug fit, and drilled another small hole to release pressure in the container. (1 metre of clear 6mm ID plastic tube from Clark Rubber is a snug fit over the bleeder valves). Raise the tube above the bleed valve and bend it down to the container and the air will collect in the top of the hose. When you pump several times all of the air is out of the lines. Took many hours to do it properly. I used genuine Toyota brake fluid. Plenty of bite now. It feels like a completely different car and now it stops. About $1300 for something that is really good now. In summary, I don't know why people are being told that they are all like that. There could be a lot of Prado 120 out there with faulty master cylinders.

                          Hi Hub,
                          questions:

                          1) was yours a grande other variant with brake assist tech or a gx/gxl?

                          2) you mentioned MC is a tight fit into servo unit - how did you get if off/out - what was the trick

                          thanks

                          aaron

                            1. Prado 2004 GXL 5 speed auto.
                            2. I rocked the master cylinder carefully until I could wedge a screwdriver with a wide flat blade in between the master cylinder and the servo and carefully worked around it until it came free. Looks like there's a seal on the inside lip of the opening on the servo you can see that matches with the o-ring on the master cylinder. The two get stuck together over time I'd say.
                            Regards

                              My 07 Prado has a similar brake pedal.....
                              But, has anyone noticed the RPM drops when in gear, at the lights, and you have your foot on the brake pedal??
                              In gear with the hand brake on and the thing idles at like 700RPM.
                              But put your foot on the brake pedal and it drops to 500 RPM.
                              Anyone?

                                Tried it in my Prado 120 GXL 2004. No change in engine RPM with foot brake or handbrake, as would be expected, because the load on the engine is the same when the vehicle is being held back by a brake, handbrake or foot brake. May be a leaky vacuum line or cracked hose somewhere, or the brake servo.
