My brake pedal feels very hard and I've lost most of my braking, the car will come to a stop but in double or triple the time it took before the cams were put on. What is the problem?

Edit: it will feel hard and not want to stop only sometimes when the car is actually driving, but from a idle to a stop, it does it EVERY time.

Sounds like you've lost intake manifold vacuum to the brake booster due to the cams.
