I replaced the motor and accumulator originally because I got a loud beeping in the cabin with lots of lights on the dash including the brake light. I replaced both with rebuilt eBay parts. Now I only have the VSC and trac lights on, but with the abs motor running a lot when I brake, and the occasional chirping from it I am not 100% trusting in driving it around much. I did get it up to speed and slam on the brakes a few times and it felt fine, but just not confident in it.
Has anybody run into this, or have any insight?
Here is a video of the noise...

i bet you didnt replace the whole assy, just the motor/pump and accumulator as you stated.
there is another element which fails and contributes to the leak/inability to hold pressure. its the piston oring assy, its best you change this too, or replace the whole mc-abs assy
