Did brake fluid flashed, I stopped and the rear driver side rim had a huge puddle of fluid in it.

I assume you meant that you did a brake fluid flush and the left rear now has fluid leaking? If you performed the fluid flush by opening the bleeders at each wheel, then you should simply have a problem with the left rear bleeder not sealing. remove and inspect the bleeder screw and reinstall after cleaning both sides, good idea to get someone to help with a LITTLE pressure while you reinstall the bleeder fitting. then re bleed at each wheel Starting with right rear. Dont forget to top off the fluid repeatedly as needed while bleeding. When done, rinse everything with water that got brake fluid on it. HTH . or you could bring it by the shop and have us do it for you.
