It seems like when my car sits overnight and i start it up for the first time, the first few stops the brakes work so good its like my eyes are gonna pop out of my head, then for the rest of the day it feels worn or out of pressure like i need to change the brakes ?? has anyone had this problem?

 

Sounds like you haver air in the the system or leaking master cylinder. Has any brake work been done before?

 

not that i know of, it doesnt make any noise its just pressure, is there a way i can check the master cylinder myself or should i just take it in to the dealer???

 

Look for a external fluid leak on the brake booster.

 

sorry but where is the brake booster????
