Hi Folks,
I have 3 LandCruisers here in SD. It's a sickness, I know! I posted the following over in the 100-series forum, but was wondering if any of you have had the following issue, and what the fix was. It's hard to imagine that I have to replace the entire assembly at $2100 as this seems like a mechanical issue, especially since it goes away in a few minutes:

This is the sound I am getting.



I bought a rebuilt pump motor, installed a low mileage pump and accumulator, rebuilt the master cylinder while I was there, and bled the brakes. Still have pretty much the same sound although now it's less random and more of an on / off on a tempo and only for about 1-2 minutes when it's "cold". For San Diego / Phoenix, that is like upper 50's. In the video you can see the movement of the fluid in the center baffle when the noise occurs.

The only thing that I haven't done is pay the $145 to have the dealer flush and bleed the brakes, although I put over two quarts to fill and bleed the system during the bleeding process. Ay caramba...

Many thanks in advance!
