About two weeks ago my brake pedal started going all the way to the floor about 95% of the time that I brake. I was told that the master cylinder is bad and needs to be replaced. I think I can do it myself but want to know if it is worth it or should i just take it in and get it looked at by a proffessoinal. Also, what is the best way to bleed off the brake system if i do change it myself and where exactley are the bleed off screws located?

Its the brake master cylinder if there's no leak anywhere-better save than sorry bring her in for you and your family safety-The brake system is the most dangerous system on the vehicle.
