yes if the back brakes dont have enough fluid the pressure in the lines will be lower allowing the switch to trip letting you know something is wrong but the front brakes will still stop you. if the front brakes are low on fluid the pressure in the front lines is low allowing the switch to trip letting you know but the back brakes can still stop you. i didnt mean all lines at the same time. hopefully you would know something is wrong long before that would happen
