Sorry, Dude, but more info would be required. Just saying it's frozen tells us nothing helpful. How about some background, circumstances, etc.? Was the brake left applied for a length of time, as in using a brake lock anti-theft device? Has the bike been dropped? Have you done any work on the front brakes? Get the idea?
Hog Dr huh? Lol, ya hard to say, did you try and remove the lever? Look in the master, how long since you changed the fluid, is the caliper free? Tons of things a DR could look into, sorry just bustin you’re *****
