It's far more likely that your (perhaps original?) hydraulic pressure
accumulator (aka "the bomb" which it resembles) has lost the ability to
store an adequate reserve supply of pressurized hydaulic fluid to fully
supply the brake assist, this is known to happen over time. Do the "bomb
test" (repeatedly depress the brake pedal with engine off until it changes
feeling, good bomb should give >10 assisted strokes) and if it fails,
replace/recharge it if you want full brake assist.
