Default Speaking of springer disc brake setups....

Buckman50 had mentioned in hammerweight's drum brake thread about using a Per. Machine brake if he chose to go to a disc on his bike, so I thought I'd put this up here.

There are a lot of springer disc brake kit options out there if you choose to go with a wide glide-type hub. But, I wanted to use a narrow glide hub 21" wheel, and everybody knows there are clearance problems on most of the caliper bodies to the angle of the narrow glide spokes.

I used a 2 piston Brembo caliper that was originally on the back of a Ducati Monster. Nice thing about this caliper, is the fact that the banjo bolt and the bleeder are the same thread, so you can switch them in the ports, so you can run them on either the R/H or L/H side of your wheel. I'm running mine on the R/H side. The caliper body clears the spokes by about a 1/4".

I had Fab Kevin cut me one of his stainless floating brackets, and used an old 11 1/2" GMA iron floating rotor with an aluminum carrier I found at the swap meet, that I vented.

With the cost of the rotor, I have less in this entire setup than just the cost of the PM 2 piston caliper springer brake kit alone, and I have bigger brake pistons and pads, and way better braking over the PM kit, it works super.

Also, I don't know if everybody knows this, but Paughco has an aluminum adapter flange now that bolts to your '36-'66 star hub, in place of the drum, and allows you to bolt any 2000-up 11 1/2" disc directly to it. Paughco's part number for it is 236BRS.

Nice job,
The cast caliper is so much more fitting than the billet aluminum!
Could a wide glide wheel be used? I have one ....lol
Any more pics of the bike to get a better overall look?
I'm still on the fence...disc or drum...

Maybe think about where you are (location)and type of riding your doing
I nearly get killed every day on my bikes ,but you cover brakes and anticipate a potential stupid move by other motorists and give yourself distance
I've come off my Honda xr650 r more times than I can count due to front end washout.

You can use a wide glide wheel, you'll just have to check the brake stay clearance on the inside of the springer legs for interference. You may have to go to a rod with female heim joints vs. the bar with male for clearance.

Here's an overall pic of the bike, but it isn't exactly a bobber. It's the bike I rode on the Hot Bike Tour last September....

Slick...and much pertier than the PM setup.

Thanks for this post Rich! I am in need of a good solution for the same narrow glide issues that you've solved in aces. I PM'd you the specifics. Thanks in advance, Dan.

Here's another disk brake setup using HD parts I came up with:
