After replacing all of the calipers and rotors on my SUV I ran into trouble bleeding the brakes. I actually was able to get good pressure from bleeding the caliper, but still ended up with a soft pedal. From what I understand the brake master needs to be replaced

Hi,

If the brake pedal goes to the floor, first make sure there are no hydraulic leaks in the brake system. Make sure the brake fluid reservoir is full. If it is, chances are the brake master cylinder is bad. Here are the master cylinder installation instruction you have requested. Here is a guide to help you step by step with instructions in the diagrams below to show you how on your car.

If you find the master cylinder is bad, replacing it isn't too hard of a job. When you get the replacement part, make sure it has a lifetime warranty. That way, you'll never have to pay for it again. First, here is a link that shows how in general one is replaced. You can use this as a guide.The new brake master cylinder will need bench bled before install. Here are directions specific to your vehicle. The attached pics below correlate with the directions.
