Bumping this thread because I have a similar issue. Brakes work fine, but I got a dying seagull issue with pump motor not stopping and alarm glitching. Sometimes it all goes away when driving over some bumpy patch of road. And today I discovered that the connection to the motor is rusted out and maybe wet? Do you think it could be fixed with cleaning the connection ?
pretty sure the seagull sound isn't the motor (although it might be near end of life). the seagull is some internal thing with the booster assembly, and you'll need to replace your assembly or have Andy refurb the unit.

Afaik seagull sound is from assembly but it might be caused by motor not stopping and creating excessive pressure. And this might be the case here because I can drive normally for quite a long time, but the suddenly this thing starts and then the seagull sound is constant.

If the motor doesn't stop, it's some electrical issue. When the motors go bad they won't run.
I do think that the sound might be an over pressurization like you suggested. Either from a failed check valve, or perhaps a failed sensor that doesn't send the shutoff signal to the motor.
I tried to diagnose sensors, but didn't find anything obvious to replace... So I ended up replacing the whole assembly.
Last week I purchased the entire master cylinder assembly for my 98 lx470, rebuilt from Julius on eBay. It arrived super clean and went in without any issues. Running strong now for $850, no core charge.
I would rather have an oem brake master with 300k on it than a brand new one from China. If I was going to put cheap Chinese parts on my 100 it would be literally anywhere except the brakes lol.
I rebuilt the booster motor this weekend with a kit from the UK off of eBay, as part of rebuilding the booster assembly. At 315k miles (I’ve had it the last 90k), I wanted to have the peace of mind on solo trips through the mountains. The original motor (as far as I know) was in fantastic shape, and likely had another 100k+ miles in her. No corrosion on the screws, the brushes were barely worn, the bearings were smooth, but looking a bit rough. I didn’t bother replacing the brushes.
