Rear Brake Caliper Question

Ok, I'm having a problem with my rear right brake caliper leaking. The weird part about it is that it is leaking from the e-brake portion of the caliper (lever on the back).

So, my question is does anyone know where to get the boot (seal, o-ring, washer, whatever (boom01)). I've did some searching and all I've came up with is a caliper kit for the piston and a hardware kit. Does the full kit from Mazda themselves ($60 so might as well get a whole new caliper if I go this route) have that seal in it? In the service manual on this site, it's listed as number 12 under "Caliper (Rear) Disassemble/Assembly if you need to see what I'm talking about.

Would be nice if I can get this seal for a couple bucks instead of having to replace the whole caliper.

P.S. This is the only part it leaks out of and doesn't leak to bad. Have to fill up the brake fluid about every month. That's from the beginning of the month till when the Brake light comes on from low fluid.
 
Just replace the caliper. Mine did it from the same spot now the other side has started. It's easier to just get a new one, replace it, and be done with it. Plus it will have a warranty that way

I was afraid of that. Guess I'll shell out the $85 and take my old Caliper up to O'Riellys and get a new one.
 
I did pads&rotors this Friday had the same problem got mine for 49 bucks at autozone with lifetime warranty
 
Most caliper rebuild/repair kits will come with it. My MP3 is actually leaking from the same exact place on both rears. Took my caliper off to take a look and noticed that "boot" all torn up. From looking through other threads it seems to be pretty common problem. I'm broke (and cheap) so I bought 2 caliper repair kits from RockAuto for like 3 bucks a piece.. Then I grabbed some brake parts lube from AutoZone for like $5.
