Think about it. Oil pressure during the braking cycle is almost irrelevant because the engine is on a very small load compared to maximum power under acceleration. A good oil will see this period of engine running well enough not to be of concern.
If the pressure is holding up during cornering and hard acceleration, just forget about it. A forward rush of oil under brakes is no problem. A backward rush without an oil supply is a big problem.
Install a low oil pressure warning switch and light to have a visual check of just when the pressure is low.
