what is an additive inverse?
you dont have to bleed it after changing the booster unless you disconnected brakes lines on the master cylinder but you shouldnt and dont have to do that. the booster probably was never bad it probably was your master cylinder
It means that there is air in your brake system or the system wont hold pressure due to a leak. the most common causes are defective master cylinders and leaking wheel cylinders.
It's the number you add to a negative or positive in order for it to equal to zero. Ex. 7 -7 are additive inverses
Say your number is n. The additive inverse would be what you would need to add to n to get zero, so the additive inverse of n is -n, since for every number, n + -n 0
An additive inverse is a number that when added to another equals 0
