For low or spongy brake pedal concerns:

check and, if necessary, refill the brake master cylinder reservoir.
bleed the brake system and retest the brake pedal feel.
if the brake pedal is still low or feels spongy, check the brake pedal mounting for looseness and correct installation. Check the brake booster and the brake master cylinder for loose mounting. Correct as necessary and retest the system for normal operation.

For a slow or incomplete brake pedal return concern:

inspect for binding, damage, correct installation or interference at the brake pedal.
check the brake booster for binding, damage and correct installation.
