Description of the problem | When you apply the brakes with full force while driving; the brakes lock up for a short period of time on one side of the vehicle, causing the vehicle to swerve uncontrollably. This is extremely dangerous vehicle when the brakes are applied with hard force at speeds at around 35 mph or higher. Luckily i am a very experienced driver and car handler and was able to react quick enough to control the vehicle one time when i had to apply the brakes hard at highway speeds when a car swerved in front of me suddenly. I have since done many tests on this vehicle myself and concluded that one wheel on the left side of the vehicle is locking up which is causing the vehicle to quickly and violently swerve. The test i did was to apply the brakes very hard and suddenly while driving on a flat grassy field at 35 mph. The grass in the field had been cut a few days earlier and was at a height of about 4 inches and dry, the air temperature was 82 degrees f. After applying the brakes hard, i would stop the vehicle and go back and look at the path of the vehicle where the brakes were applied. There was clearly a patch of ground the same width as the tire, exposed down to about one inch below surface with no grass, where the one wheel that locked up, skidded and ripped the grass and dirt up. I have done this test multiple times and based on my results have concluded that one wheel on the left side is locking up. I did not that if i repeat the test several times back to back, the problem seems to correct itself at times. But always on the initial test, the lock up occurs. I have had it to two different toyota dealers and they both told me that the brakes are working as designed. If yes, this is a very dangerous design and i don't feel safe at all, and i also noticed that there are several other complaints about the brakes for this 4runner model years. |
