So as the title states I just got an alignment and I noticed that they put a rod holding down the brake pedal for the alignment and thought nothing of it. Car is working fine and braking fine but i opened the hood and noticed that it leaked a little bit from where the cylinder meets the booster. What should i do?

replace booster and master cylinder. Has nothing to do with the alignment.

I only recommend the booster because master cylinders can leak into the booster and eat away the diaphragm inside. I do a ton of alignments and you shouldn't need to press down super hard on the brake pedal is just holds the wheels while you do the caster sweep.
