usually if the fluid is leaking out of the boot, the seals inside are bad. Does BDR not use an aftermarket like Wilwood or similar? If so, the rebuild kits are like $20. I have to rebuild the ones in my race car annually. If it is a wilwood type, you can find a local dirt track shop for a rebuild locally. daymotorsports is in Tyler TX which I don't think is too far from you.
i would assume you have somehting like this:
