An old idea seen on ancient Goodyear brakes.The inside caliper is pretty trick.
Tracy O-Brien brakes were well recommended on the Hummel builder's list, and what I plan on using when I'm closer to being finished, but won't work if you're in a hurry.We use Matco 5" wheels with internal calipers on the HP-24. It is a solid system with lots of capacity.
There are some low-cost disk brake solutions out there that use Azusa 4" and 5" aluminum wheels. But all of the ones I looked closely at have a large installed width (with extra frontal area and moment arm on the gear leg), a maximum bearing size of 3/4" ID (and they're ball bearings, not high-capacity tapered roller bearings), and the disks themselves are relatively wimpy.
One neat looking system is the Tracy O'Brien C90. However, the ~$100 cost of the brake linings is a bit off-putting:
I have O'Brien brakes on my Cleanex and they work well but can fade quickly when working them hard near full gross. My gross weight is set at 1250 lbs. The CVJETKOVIC CA-65 (from what I read) can have a gross weight up to 1500 lbs but some are at 1200 lbs (http://www.cvjetkovic-aircraft.net/) so depending on the gross weight the O'Briens may work for you. I think he reommends them for no more than 1200 gross.Tracy O-Brien brakes were well recommended on the Hummel builder's list, and what I plan on using when I'm closer to being finished, but won't work if you're in a hurry.
Like you, I want good brakes for short strips. Long strips in WV is as scarce as hen's teeth. Don't want any Clevelands. Guess I need to get on the phone and talk to Matco. They are in Salt Lake, Ut. Friend of mine lives in western Wy and his daughter lives close to the Matco business. The owner is also the company engineer. My friend uses Matco on his Bearhawk LSA and speaks highly of the owner and the brakes.There's been very little mention of the weight differences in the different brands. That's always one of the top considerations for me and was the reason I used the Black Max wheels and brakes. Light and cheap. 15# less than the Cleveland 500x5 set sittin on the shelf here. They also won't hold s**t. I bought the single puck and they were near useless so called the nice guy and he sent me a double puck set to try and they were fair so I'm running those. I don't recommend the Black Max. I got double puck Matcos on this 701 and they're fine and they've been abused. The light weight of the 701 and the high idle thrust of the 912S means the brakes are used constantly to keep the thing reined in and get heavy use for STOL...mine have 500 hours on the pads and still lots left. Riveted. That's probably what I would use after doing the homework comparisons. Clevelands stop good but are heavy and expensive. Certified stuff is usually that way.
Yep, at one time I owned an early Bonanza with those brakes and to put it bluntly, they were a pain in the a**.An old idea seen on ancient Goodyear brakes.

I hope Matco has done a better job of engineering than Goodyear did. I see that they at least have the riveted lining instead of Goodyear's round puck that would wear thin and fall out of the shallow depression that held it, jamming the brakes solid right at a bad time, like rollout or takeoff. Getting at the brakes meant taking the wheel off the axle, and the disc was held in the wheel by six spring clips that cost, in 1995 when I last checked, $86 each. I had them on a Champ, and later on my Jodel, and got rid of them off the Jodel. The discs would rattle and had a tendency to warp into a cone shape if they got too hot.
