Weird brake vsc trac and warning chime issue

[OC2003]

Today my mechanic changed my brake accumulator and pump motor. The entire system was then flushed and bleed using Toyota software. Everything see to be working properly with abs pump doesn't run nearly as much or as loud as it used to. Pedal fee eels bettr etc.
My issue is if I pump the pedal five or 6 time in quick succession the vsc and trac lights as well as the brake light and buzzer go off for about 7 seconds. Any ideas?
Thanks
Randy

I took it out this morning and drove it like a rental through he lcal canyon. The vsc kicked in as it should and did it's job. All he forst road gates were closed due to rain n the burn areas so I couldnt find anywhere that would cause atrac to kck in. I m sure all is working as it should. I'm just wondering if he buzzer and lights comng on is. Normal if you pump the pedal multiple times in quick succession? I ask that someone go out and pump their brakes with rig running 5- 10, times and report back.pkease. my. Curiosity is killing me

I just went for a drive. While at a stop light I pumped the brakes rapidly about 11 times, and the alarm came on. It went away in seconds. It is normal.

The pump in your hydraulic booster assembly just needs a few seconds to re-pressurize the system.
