(SOLVED!) 2004 Lexus LX470 Brake Failure (I'm getting sick of this lol)

[GTV]

Fortunately the piston is intact. I'm looking to buy a USB-OBD II dongle later this year when I (finally) graduate highschool. Can I buy just any dongle or does it ha e to meet a specific requirements outside of being obd 2 to USB?

How-To: TechStream In 5 Minutes

Getting Techstream up and running can be a bit of a pain. Hopefully this helps someone get started quickly. Step 1: Purchase an OBD-II / Mini-VCI interface. - I have sold out of my cables and supply chains are back in order, so no reason to purchase more. Anything like this will work: Mini-VCI...

General update:

I think it's safe to say the problem is solved. It should be noted that the red handbrake light was constantly on the dash before repairing the rear right brakes (despite handbrake being fully disengaged) and when the BEEEEEP sound went away (reference from an earlier post in this thread), the handbrake light also went off. Been on the road the whole day today with my old man, not a single problem from the brakes. Made sure to beat on the car and mash the brakes (don't roast me lol) and everything held up as it should. Thanks everyone!

P.S. we went to Lexus dealer and picked up a new CV Axle for $550 (well it's equivalent in Nigerian Naira)!! Ordered a set of clips from same dealer and it'll take 2 weeks to arrive. Kinda looking forward to it but also kinda not lol.

Ahh I posted about this brake issue a while back, i also had the pogo stick issue right before that. Flushed all the AHC fluid which helped but I ultimately removed the AHC system.

If you do hear this annoying beep again, its likely your brake booster motor. I pulled a used one out of an itsybitsy Montero at a pick your part for $15.

It's very wise to get Techstream before spending money on anything else, especially with AHC. It's about $25 for the cable and the software is free.

My '07 had the same symptoms you describe and it was the sensors.

This. It was (apparently) NOT the accumulators. I took down the driver side front accumulator to check it and it passed the pencil test. Front end sitting in LO position due to release of fluid. Stuck it back on the car and topped up on fluid and took it for a spin b4 taking off passenger side globe and the car is riding like completely normal now. Probably even better than it was riding b4 but maybe seeing the dark side has made me biased. Gotta get my hands on a Mini-VCI cable.
