Generally, any road brake lever or brifter is compatible with any make or model road brake caliper so your current brifters will work fine with Dura Ace brakes.

That said, the centering screw on double pivot brakes is completely unnecessary. You can easily center them by hand just by pivoting the entire caliper and if the mounting bolt is reasonably tight, they will hold their adjustment indefinitely. Your current brakes should be easy to center and keep centered.

If their performance is not to your liking, new and better brake pads (Kool Stop Salmon pads are among the best) are a much cheaper upgrade.

BTW, do not buy Campy brakes to use with Shimano or SRAM brifters. Campy brifters have the brake quick release in the brake levers and none on the brakes themselves so you will not have a qr anywhere. Conversely, Campy brifters with Shimano brakes give you two quick releases and the brakes will clear nearly anything.

Any Shimano dual pivot caliper is going to be compatible with any Shimano brake lever. That said, I would not spend the extra coin for DA calipers. They'll be slightly lighter than 105 or Tiagra calipers, but won't stop your bike any quicker.

There are other places to spend your pennies.

Go with Ultegra 6600 or 6600-G (Ultegra SL) series calipers. They are fully compatible with your 105 levers whereas Ultegra 6700 and Dura Ace 7900 are not recommended unless you are using 6700/7900 levers as the cable pull is different. Dura Ace 7800 will also be compatible but as someone else pointed out, on the bike you have the weight difference will not be worth the extra money over 6600 series. All of the above have the centering screw which I personally find very useful.

You should be able to pick up a mint pair of SL calipers under $80.

I would expect the OP has Tektro brakes as they are the most common "no name" OEM calipers. They are not the lightest brakes out there but they do work and work well. Their glaring weakness is their second rate pads and that is easily and cheaply remedied.

If the OP insists on upgrading, I agree that Ultegra 6600 (or earlier) or any version 105 double pivot calipers would be fine performers at much less cost than Dura Ace.

If you're using the centering screw to center the brakes more than 1% of the time, you're doing it wrong. Dual pivots can easily, and precisely centered by hand. The "centering screw" not only centers the caliper, it moves the arms downwards and increases spring tension. Most people think it's just a centering screw. No, it's not.
