Been thinking about upgrading my 2004 Road King brake system, which is running DOT5 fluid and rubber lines. At first I was thinking about just replacing the lines, but when I looked at the cost of that I figured I could spend maybe a few bucks more and just get a set of used 2008+ Brembo calipers and steel lines with the DOT4 fluid.

Question is, is that a straight swap - will the those newer style calipers bolt right on to my 2004 fork legs? Will they work with the 2004 disks? Will the newer reservoir fit where the old one was, no mods?

Thanks for any info!

 

Yes, the calipers will bolt up but you will need to go with the new rotors. The MC reservoir will also fit with no problem and you might want to pick up a new clutch lever to match the one on the brake side as they are different than the ones you have.

 

Awesome - thanks! Just scored a lightly used setup on ebay. Now just need the rotors and a clutch lever.

 

By the way, can anyone confirm for me that the bolt pattern for the rotors has not changed since 2004? I believe the axles have gotten fatter at some point - presuming I don't need a new wheel to put the new rotors on!

 

Bolt patterns are the same.

 

It should be the same, however there is a piece of the puzzle you are missing. First off get braided lines. It will be well worth it as they do not flex like rubber and will provide a much firmer brake. Second, the Brembo's are designed to use 11.8" rotors so you might want to pick some of those up. You can use your 11.5 but part of teh pad will not be used which seems like a waste to me.

My Dyna has Brembo bagger calipers. Steel braided brake lines. Lyndall Carbon composite 11.8" rotors and Lyndall gold pads which are required for Lyndall to honor their lifetime warranty on these rotors for the first set of pads. I can stop with one finger like a sport bike if I w want with this set up. Our VROD has the same setup and stop even better as the master cylinder is a little bit different.

 

Excellent - thanks for the info, all. The setup I just picked up on ebay was a 2010 bagger takeoff and included the stock black braided lines, master cylinder, brake lever and calipers! Definitely looking forward to some one-finger braking!

 

Pick up some stock 11.8" rotors and you are golden.

 

i don't want to spoil the party but i recall reading in the last week or so the center hole on the newer rotors is different - search for wheel swap threads

 

I want to do this on mt 2001 FLHTC..keep us posted on how it went.
