stiff brake pedal

I just finished changing my coolant hoses and reinstalled the intake. Went for a test drive and my brakes are extremely stiff and hardly stop. My PSM faulty light came on and also the check engine light. Is there a hose I missed or pinched or a plug not plugged in? Please help. Frusterated.

Also, in park, the rpms are at 2000. This is obviously the reason for the stiff brakes. Any ideas as to what making the idle so high?

Check for a vacuum leak. The power assist brakes need vacuum to the booster. If you're not getting any assist (hard pedal) it is possible that you have a vacuum leak. Since you have replaced the coolant pipes (removal of the intake etc...) you have have either missed a vacuum hose or have a vacuum leak at the intake thus the high rpm's.

Probably just a hose is off. Try to trace it from the brake booster first before you disassemble anything.
