Narrative:
As I came to a complete stop on the south side of the ramp; my right brake was very soft; or weak. It felt like there was no pressure. In order to determine if if I needed to write the brake up I pumped the brakes and tried to see if I could obtain any pressure in the right brake. I was trying to determine if the pressure had just bled out; or if it was gone completely. I was able to get a little pressure; but determined that something didn't feel right and decided to shut down with plans to write up the brake and call maintenance. I chocked the nose gear and went to spin down the right engine when I noticed a small puddle underneath the brake reservoir in between tire 3 and 4. This wasn't a big surprise as I had noticed that something was wrong prior to shutdown. I decided to go inspect the situation further and complete the walk around. As I got to the back side of the right wing I saw the entire gap between both tires completely up in flames. I immediately went back into the he airplane and got the fire extinguisher. I extinguished the fire with in a minute of noticing it was on fire. The brake fluid was pouring out from the reservoirs for several addition minutes until maintenance arrived and helped monitor the situation.
