The job takes a mechanic around 1-2 hours and they will bleed the brake system too. If you are going to do this, get a good repair manual and read up on what needs to be done and what tools you'll need. Look at the location of the master cylinder and see what it will take to access the bolts to remove it and the brake lines too, they can be tough to access.
