Kinda didn't know what sub forum to post it in... Goes over the basics and all the parts needed

More pics and info on the mounting bracket? I want to retain my factory handbrake.

Also, I am using a 3/4 Fully Torqued Hydro, do you have any recommendations on caliper selection for that size MC?

There really isn't any good pictures of the caliper mounting bracket. It's literally half inch steel with holes in it welded to fit the calipers. Like... nothing to it.

There's a link to ASD's sizing chart for calipers that will give you an idea. IIRC the dynapro 220-8756 calipers I have are supposed to be good with a 3/4" master. But I still have to yank pretty good on my 5/8" to get the wheels to lock. But that also is likely because my pads haven't worn in yet. They get stronger the more I use them.

Do you think those weld on tabs on ebay will work well?

[shiboujin]

Got a link? I've never seen those before. As long as the welding job is good and the metal is up to the task, there really isn't a reason why it couldn't work well.

That looks like it will work. But that's also only for the factory calipers. I didn't have any success with my factory calipers with a 3/4" master.

Well, i wonder if those wilwoods for the 3/4 would work with this bracket then. It looks like a really easy piece to make, though

[shiboujin]

Those mounts (the ones you linked to) will only fit the factory calipers. The wilwood calipers have no threading in them. The factory calipers do. The wilwood mounting ears are also much father apart than the factory calipers. I would find a welding buddy and have them make something for you.

I can weld it if I have the bracket. Ill just buy the calipers and pads and sit it on the rotor and make measurements. Im guessing thats what you did?

I have a house current welder. So I found a buddy that welds for a living. He heated up the cast metal and did some 220V jazz on it. The bracket itself isn't too hard to make.
