Planning an upgrade from drum brakes to Cobra brakes. In the M2300K kit and a couple of other kits dust shields and antimoan braces are included (such as the M2300M kit) - I know some folks run without them. I just want to know do they really make any difference, or are they just nice to have. The shields are pretty self explanatory - anybody have any problems because they didn't use them?
And what exactly do antimoan braces do? Is it to prevent some kind of vibration and what is the difference with not using them vs using them? This is on my donor 1990GT, which is rapidly becoming an anti-donor!

I went from drum to m-2300-k with northracecar's brackets and had some moan. Mostly when turning corners and moving slowly. It was very loud when it happened. I shoehorned the anti-moan brackets on and have had no more problems.
I wouldn't think a properly designed disk brake bracket would moan. If it's strong enough, it shouldn't flex which should alleviate the "moan". I designed my own bracket and I don't hear a sound from them plus it was cheaper. You might try Mike Forte's disk brake bracket. It's a super nice looking bracket and should be plenty strong but consult him to see if he recommends an anti-moan bracket. www.fortesparts.com
As for the original question, I don't use a dust shield or an anti-moan bracket. Don't need either in my opinion.
What you are saying is true, BUT... What if Ford was already producing SN95s, & there was no moan from the rear brakes? THEN they started producing the Cobra model, w/larger diameter brakes, which required a longer mounting bracket for the rear caliper (which allowed more flex, & hence, "the moan"). Ford would be faced w/the prospect of designing, tooling up, & producing a new, stronger bracket (which, by the way, would require changing the length of the rear housing & axles - to allow for the thicker metal of the new bracket). OR, they could produce a quick, inexpensive, bolt-on stamping, which would not require changing any of the existing parts already in inventory. Sometimes a band-aid fix is completely adequate, as well as financially preferable.
