Hello, I have a Toyota Camry Altise 2010, 2.4L, automatic, 168000kms, that every time when I am applying a sudden or faster brake to stop, it feels like I have a load at the back that briefly jolts (pushes) the car in the front (like a loaded trailer with a faulty hydraulic braking system that pushes in the car's towbar).
It feels weird since the car is stopped, and the brakes are slightly released from the "pressure to stop" previously applied and that jolt/push is happening. No concerning or unnormal sounds/noises can be heard from the car's engine, transmission, brakes, or any other key components at any time. But a little winning sound in the steering wheel, but this is since I have purchased the car at 145000kms, and at that time I changed the steering wheel fluid and the winning sound been less quiet but now it slightly more obvious.
No leaks under the car. I have replaced the tranny fluid with the original type at 146000kms and I could feel that the car had much more power in acceleration (now it is more sensitive when accelerate from a stop position) and it shifts gears verry well. Cheers!
By any chance, would I be able to connect a cheaper device, that could identify an issue like this? Is there any OBD under $300 be able to tshoot this kind of issue?
More expensive scan tools usually have greater abilities than less expensive ones. So you might find something for $300 that will work but you're certainly not assured of this until that device is actually plugged into your OBD2 port. Any 'coverage checker' website stating for a device saying "it will do this and that on your specific car".. be very skeptical because all tools have their limitations. Could easily be why Scotty suggested you find someone with a good tool and the knowledge to use it correctly. Hope this helps
That sounds like a classic ABS system failure. If a guy like me hook up his fancy scan tool, drive it and check the ABS data. Hopping something like a bad sensor or a bad ABS modulator will do that
Hi Scotty, thank you for your quick reply and for all the advice you have provided during all these years.
It does not feel like a fail on the breaks to be honest. That is, because the car is fully stopped for 2 to 4 seconds when the push happens, and it might be that my way of describing the issue was slightly confusing, but as a second thought, could the transmission have an issue which will make the gear system to slide forward when the breaks are studently applied? I will take your advice and take it to a professional if no other OBDs could give me feedback on this, but I don't know anyone with a professional OBD. You probably referred to an actual Toyota dealer, or any mechanic, that have the Toyota software license included in their OBDs, to be able to investigate such an advanced issue.

@scottykilmer I've been changing the engine mounts and found the right-hand side mounts (top and under the engine ones "shut" completely. Also, the other (front and left) pretty busted too. And that explained some of the jolts when sudden brakes applied. The engine movement was obviously bad for the tranny too. It might be some other problems with the tranny but still works well, no noises or unproper gear shifting probably a bit of slippage after changing the fluid 4 years ago.
found some braking system issues, since, still, at sudden brake then accelerating the car will have a moment of hesitation than the wheels will do a bit of burnout. Unfortunately, I did not check the car with a mechanic as I cannot find a trusted guy to have it checked with a proper scanning tool... But when I replaced the brake pads, I found too much grease on the pins (you know which ones...) which will explain the uneven brake pad worn-out...the outside ones have worn-out more than the inside ones. Also, that might explain the reason why the sudden move of the car when taking off from crawling motion or from not moving. Most probably the outer brake pads were getting stuck on the front disks...
Two months ago, I had to replace the PCV Valve, and its hose, therefore, I purchase a claimed OEM package from Aliexpress but after 2 months (yesterday), because of the rise in the temperature due to the summer here in Aussie, a strange whining noise was occurring after 10 + min of engine running. The sound will stop when the shifting gear was in reverse, or the driving wheel was turned. I found that the OEM hose was collapsing while the suction transfer of the gases was happening, so the noise was due to the hose shrinking due to the bad rubber product. Initially I suspected the steering system, and I flush it (something that it was due anyway...). But the noise was still there. There was nothing on the internet to help me with this noise so took me a few hours in total to identify (that is because I was afraid to keep the engine running so I won't damage something while t-shooting the issue). I could not find an actual OEM hose, so I purchased a Moulded HEA (kind of high-pressure rubber hose that fitted on both ends ok). I'll keep an eye on it as I don't know how it will behave on high temp as well...
This is the YT link about the whining noise FYR: https://www.youtube.com/shorts/XpMPcDuRwAE
Please bring up these issues on your channel, if you can, so people can save some time chasing these types of problems.
PS: Your high end OBD2 gear is hard to find anywhere apart of USA. What will you recommend for areas such as Australia?
Many thanks and have great end of year!

Hi Scott and all,
I have purchased an KINGBOLEN S6 OBDII and scanned the full system.
As Scotty previously suspected, the ABS came up with four errors. At this point I have cleared them and I will use the scanner next time I drive the car and collect live-data to see exactly if any of the errors will reoccur.
Vehicle Information Make:TOYOTA
Model:Camry Year:2010
Mileage:181071km
Vehicle Software Version:V10.44
Inspection Result:
ABS (Anti-lock Braking System)/VSC (Vehicle Stability Control)/TRC (Traction
1.C1201 Engine/EV Control System Malfunction
2.C0365 Deceleration Sensor
3.C1241 Low or High Power Supply Voltage
4.C1288 Error in Matching of ECUs
Many Thanks!
@santes Hopefully the new Kingbolen scanner will aide you in properly diagnosing the issue. Thanks for the update.
