    Brake system failure

    Hi members, yesterday when I was driving my Demio when drepressing suddenly brake pedal went all the way to the floor. Luckily I was near a garage & took the car for inspection right away..however after about 10min or so brake system came back to normal without having to do any repairs..I searched the forum/Net and found out that, 1- Could be a brake fluid leak- which was not the case & the mechanic did a through inspection 2- Error in the braking booster- highly unlikely according to mechanic’s advice 3- failure in braking master cylinder- which mechanic suggested that if the issue happens again he will do an inspection on the component.could be an internal issue he said. he advised me to drive the car normally for the moment and not to panic. I am skeptical and I need a second opinion on this and appreciate if you guys could shed some light. thank you.
  2. Hi All, Need some advice from the experts here regarding a possible gearbox failure in my NZT260 Toyota Allion (1NZ-FE). Couple of days back when I was on the way and fortunately closer to my home the car started to rev high up when accelerating and started experiencing a huge power loss to the wheels. I got home and I have kept the car in place till today without moving it to prevent any further damage. So basically the car engages the Drive mode and when accelerating the car barely moves (does not get past 20 km/h) but the engine revs high up. Only reverse is working without any loss of power. No noise or any cranking is heard from the tranny. Mechanics suggest that it is a common failure in CVT type transmissions in Toyotas' and it cannot be repaired, but replaced the whole transmission in full. All the maintenance have been done through Toyota Lanka and CVT transmission oil was replaced at the recommended intervals right throughout (CVT oil was changed in the last service as well). Toyota Lanka says the part is more than 900k, but recons are around 175k the least. The car has close to 186k mileage. Has anyone else running similar transmission experienced this? Is it possible to repair? If it has to be replaced, any tips on buying the part, replacement? Value all your ideas regarding this Regards.
  3. Hi Everyone Recently I went though some interesting details while doing an ECO test. The test passed but I thought everyone should know the details. This applies to both diesel and petrol vehicles. 1. My vehicle has very low emission standards after an overhaul 20,000KMs ago, 1kz-te turbo diesel engine maintained by Toyota and the test was done soon after a service. 2. The test failed when the officer stepped on the engine and reved it over 5000RPM. Simply the guy stepped on the accelerator in 1 second (I timed it). The engine smoked all 3 times because it failed to calibrate intake and output ratios of diesel with the turbo lagging after 1 second rampage to the floor. it was always an under burn because the engine was trying to respond to an overfed intake, By the time the equilibrium was found the test was on the last last few seconds. Therefore the average test reading failed. 3;. Having some knowledge on the subject matter, I started arguing on the test result and the way it was performed. I claimed that the person incharge was not trained on fundamentals. Despite my option to take the test within another 60 days after so many repairs listed to overcome the problem, I opted to do the test again in 30 minutes after the next person in line. The test passed, the engine had fraction of emissions, almost equal to a common rail direct injection engine. 4. I did not go on the easy way of throwing money at the problem of influencing the officers. What happened here? Let me explain. 1. An engine cannot respond to an immediate floor level acceleration in 1 second. The test says - take it over 3500-4000RPM in 3 seconds. What happens is, there is a notice on the computer instructing "ACCELERATE" and the guy ramps to the floor. Engine reaches the red zone of the RPM counter. My 2nd test was done between 3500-4500RPM with proper acceleration. 2. The engine that runs on 5000-7000RPM blows all the smoke dust that is accumulated inside the silencer over 1 year. We NEVER rev engines over 4000RPM on normal running. Not even on an up climb. It is only on an occasional quick deathly overtake and even that I doubt over 5000RPM. The testing should NEVER force an engine to this range. Any engine manufacturer has a warning on red zone RPMS that will definitely damage the engine. The simple colour indicating the RED zone of RPM is to avoid going there. 3. They do the test in this crazy way to reject the engines because there is pressure from the authority (RMV) to stop the smoking. RMV has started penalizing the test officers for passing tests of those engines that are later smoking on the road. This is now going in the typical Sri Lankan viscous cycle of hitting the consumers. Consumers spend over Rs5000-10,000/= to temporarily clean up injectors and replace air cleaners. Some even wash the silencer inside. However the motive behind 1 second floor acceleration is to play safe and fail the engines to avoid penalties by officers conducting the tests. Even if RMV catches on the road the records will indicate that it was failed once. One other reason to rev up is, the actual RPM and the echo based RPM reading on the computer is showing a difference to the lower side. Therefore they floor it to compensate the gap.Instead of doing all this unprofessional over protective conduct of tests, what they really should have is a good software that takes the tester through a good acceleration cycle with a graphical illustration. If the government is so keen on this and care about the environment they should CERTIFY this software and regulate proper usage. if we do not get this properly established like in other countries, lot of innocent people who are not conversant on the detail are going to spend a lot of money when they are already finding it difficult to make ends mean. My polite request - Share is with many people as possible. My intention of writing this is for someone to get this forwarded with proper influence to the Minister of Transport and Commissioner of RMV. For those who go and get into this sad pit, know your rights, show the vehicle manufacturers manual, argue, demand your rights as consumers but be genuine with emissions. We have to protect the world for our younger generation. If your engine is bad get it fixed. Regards Nana
