take a look this link. it may need to replace one of this part ( Valve Seat) in the faucet, However, it is a bit of hard to replacing it, take a look the site. if you can't fix it or no tool, get help from other.
Turn off the main water supply. Open the faucet, use flash light to check. You might need to change the bushing, a metal piece which will chip your new rubber seal if it is rusted. Hope this helps.
