Not much information to go on so I will ask, how are your brake pads?

Could be a wheel bearing on it's way out or worn suspension. Have even found that after working on a car, if you don't do the sway bar link pins tight enough it can cause noise under braking. Have you worked on the front end lately?

Has the noise only started since Holden working on it?
One quick check is while the car is on the ground, get under the front near the wheel on each side and try and grab the sway bar link pins and wiggle them around to see if they are loose. If too hard, drive the front wheels up onto a couple blocks of wood or something to give you more room to get underneath the car. The front wheels have to be on the ground taking the weight of the car for this to work........a sloped driveway maybe. Anything that will give you clearance under the car

Don't know tbh. when I come up to a round about and put brakes on, the brakes work but make this cherrrr chooo sound if it was brake pads wouldn't it be making this sound all the time? it happens maybe once every two weeks so very random

Seriously doubt it'd be link pins.....Worn link pins rattle when hitting bumps as well, not just under braking.....It's quite possible either the slide pins in the calipers are starting to sieze up, or maybe even the booster is starting to go....To check the booster, start the car and before driving off, pump the pedal a few times and see if you can hear noises from that. Look for signs of brake pad material on the rotors....This is a sign the slide pins are seizing up in the calipers.....2nd thoughts, grease them up anyways....This can only be beneficial anyways.

There's a few starting items

Listen for noises from the booster...in the engine bay...while the engine is running? Wouldn't be able to hear anything but the engine running.

Brake pad material on the rotors??..WTF? On a brake rotor that is a flat surface, where is this brake pad material going to be?

Before you go 'seriously doubting' other peoples ideas, have a look at your own ideas and how shallow and uneducated they are
