When you park the car, do you keep your foot on the brake pedal once the car is turned off? We had an issue like that in the past and finally worked out that sometimes my wife would park and stay on the phone for a few more minutes, and she kept her foot on the brake pedal so there was no brake boost left

If that's not the case then you've checked the obvious sources. Fluid level ok?

Thanks for your help
