What could be the problem? The brake booster does look pretty old and rusty...Has brake fluid..It still stops good you just have to really press on the pedal hard....is that usually a brake booster? It ckind of does feel like press a brake pedal with the engine off

Put you foot down on the brake with the car off. Hold down and start the car. Pedal should move down when the car starts if booster is working. Dan

It may have been a couple pounds heavier, but to me that's not a big deal.

That problem could be caused by the Master Cylinder as well. Be sure to check that out before replacing the brake booster.

I had a master cylinder fail where it was harder than normal for a few weeks and then one day while travelling at 70 mph I pushed the pedal and it was like there was a brick holding it up. Fortunately I had an operating Parking brake as well as a four speed so I had options that an automatic transmission might not have had. It was scary going 70 mph and not having a brake pedal in Washington DC beltway traffic. I will never forget that day...

Good Luck!
