TL; DR at the end but please read the whole story because TL;DR doesn't cover it well.
I think this is the car's retribution for installing used and/or refurbished parts on it. This is a spin-off from another issue i'm having: New year, new problems. 2004 LX470 is a rolling pogo stick. - https://forum.ih8mud.com/threads/new-year-new-problems-2004-lx470-is-a-rolling-pogo-stick.1275979/#post-14306406.
Anyway, both front AHC accumulators (globes) on the car are toast and the car is a rolling pogo stick, going over bumps at any sort of speed results in the front oscillating like a wild bull. So, we (my dad and I) were coming home, going down the highway, and as my amazing luck would have it, I hit a bump at full speed and the front of the car went slightly airborne TWICE (you could literally hear the front tires screeching as they touched down lol) and we felt the mother of all oscillations and I hit the brakes as there was some traffic up ahead. As we entered the traffic, the car's horrible "brake failure" constant BEEEEEEEEEP started sounding. And the brakes seemed fine at first, now it must be noted that we are rolling slowly, my foot constantly on the pedal. The car up ahead comes to a stop and I press the pedal down a little to stop the car and it just keeps rolling, the "brake failure" constant BEEEEEEEEP is still sounding throughout the interior of the car and I literally stomp on the pedal and come to a rolling stop (as opposed to a screeching stop) and I damn near had a heart attack.
So I stomp on the pedal and the car comes to a stop and then there is some sort of vibrating/grinding/whining sound coming from behind the brake pedal (but in the engine bay), and then the brake pedal literally fricking rises up from the floor (because I am essentially standing on it), pushing my leg upward, and then when the pedal comes up, and the car has stopped, and the brakes feel to be working normally again, the vibrating/grinding/whining sound stopped. Anyway, eventually the beeping stops on its own and normal braking returns except that when the brake pedal is depressed and I turn the steering wheel, there is a harsh, not too audible, grinding sound and the vibration from that can be felt in the brake pedal (different from the earlier mentioned vibrating/grinding/whining noise).
Soooooo, we stop on the way home to grab a bite, we enter our car and resume on our no-longer-merry way and as we get into our neighborhood and hit some bad sections of road, the car is being real bumpy and jumpy, the "brake failure" constant BEEEEEP returned, and every single time the car is jumping up and down and I go to press the brake pedal, it's super stiff and I have to force it down, and then it goes down and the car stops, cue a loud vibrating/grinding/whining noise and the brake pedal rises back up. Sus.
Also, there are fluid droplets (or most probably melted grease from a crappy and refurbished CV Axle) sparingly lining the driver side wheel well. I don't think it's brake fluid because if it was, the rim would be coated in it, however, the rim is noticeably dry while the wheel well (literally all around the travel path of the tire and some other select areas) has droplets of fluid (which again I highly suspect to be melted grease from a trash CV Axle). Also worth noting that same fluid was sighted on CV Axle boot (the boot on the side farther away from the wheel).
TL; DR: Failed accumulators and poor visibility due to nighttime cause LX470 front end to go airborne on the highway, brake failure ensues. Brake doesn't work when car is bouncing like a pogo stick and makes a vibrating/grinding/whining noise when it does work. Pretty sure the car hates me but ok :/
Constant "brake failure" BEEEEEP just in case:
