I'd check the brake pedal return spring as they tend to break leaving a vague pedal feeling. I've just rebuilt a pedal cluster using bushings from our host and an OEM (ouch!) return spring. The cluster was very rusty and the brake pedal stop was almost gone. The bell crank bushings in the brake booster mount were worn out / replaced too. After media blasting, welding a new stop (new rubber grommet too), to the pedal cluster, the brake pedal feels normal again.
