I switched to Lyndall pads and stainless brake lines on my 07 UC and I'm still unhappy with my braking,would the semi-floating HD rotors help much or should I go to the 08 calipers and rotors?

I ran th HD semi-floating rotors on my 03 Road King. They do help, but not enough for me. I changed over to the 08 HD brembos this winter and there is a major improvement in my braking. I was on a short trip with 19 buddies this last weekend and had two of them try my bike (one has a 2002 Ultra and the other one a 2004 RKC) both told me how impressive the braking is, and when I said that I believe that it has reduced my 60 to 0 distance by 15 feet they both said "at least if not more".

Floating rotors by themselves really don't add performance to your braking. They do handle heat better, so they will help avoid brake fade under repeated stops. For better performance, change the calipers and maybe the master cylinder. I would recommend floaters afterward or in addition to the new calipers, though.

What he said +1.  Light weight floater 300 mm w/Brembo may be your ticket.  I do not think you neeed to change the M/C but I will know in a few days as I am taking both apart.  I will also do a fluid volume test.

Fastharley'

I was going to rebuild my 03 master and use that, but came across a take off 08 brembo master for $45. Not much more then the cost of the rebuild parts so I went that route. It also came with the switch covers, and since the covers were in better shape then mine I used them so I ended up saving $. I am interested in your findings on if it makes a difference on the master.

Thanks for the feedback guys....From what I read elsewhere a full floating rotor is suppose to help braking all the way around because of better pad alignment but I guess the cost is about the same no matter which way I would go.

On the new build I went with Brembo calipers and Brembo rotors. I didn't care for the HD brembos. I can tell you this thing will STOP with very little effort. I'm also glad I went with the Traxxion forks. They keep the front end from diving on hard braking and ergo...make it safer to brake hard.

If i had the $$ i'd go with the the lyndall lightweight floating rotors.That will take about 8 lbs off your rotating mass(unsprung weight).Then go with the brembo's if'n yaa gots the$$.Nice bike,rob.

you guys are on track, calipers make the biggest difference, more pad area more stop, forget 2 piston junk, i installed 6 piston hawg halters with brake tech floaters, direct fit works great, as stated forks make a difference, harleys mushy setup robs braking when the forks dive, theres options out there you need to spend a few more $$$$ to get the GOOD STUFF

Are the HD Brembo calipers a direct bolt on for an 02 E-Glide?
I've often thought about switching to aftermarket calipers, but never did because.....
a) where do get the brake pads from when you need them?
b) I can get HD pads at any dealer and indy!

Direct bolt up but you need 300mm rotors.  I would not use the stock HD pads as they do not stop that well + make dust while wearing your rotors.  The removable rear caliper without removing the rear wheel is worth it by itself.

I found that the rear wheel is also easer to mount to the bike due to the thinner mounting boss on the 08 Brembos, but the Rear caliber is not a direct bolt on as are the frount calibers. The 08 rear mount has a 25mm axle bore and will need to be opened up for the 1" axle found on 02 - 07 bikes. Since the mounting boss is also thinner a new spacer is needed for the right side. I cut down an extra left side spacer to .71.

I believe if you search someone (I can not remember who) did an excellent pictorial on this very subject.  The piece was very well done.  I did not want to say so as I could not remember who wrote it.  If you plan doing this job search for the person who did it.  It was several months ago & well worth the time to invest in finding it.   The person also converted & used the rear master cylinder & showed what modifications are needed.  I have no knowledge in whether you need to change the front & rear M/C, that you will need to find out for yourself.  Do a volume check on both & if it matches, you will not need to, if both M/C's are not the same, you will need to change them.  You must match the M/C to the calipers in volume.  I am sorry I can not give the author on the article.  Maybe I could get someone with a better recall than I.

I believe 03dragonrk did a post with a lot of pics on his conversion to the '08 Brembo setup.  You can do a search to find it.  I just finished mine on my '02 Ultra and i love it.  Lots of reasons to change.  The brakes on my '02 have gotten real soft and was ready to go to S/S lines and clean the calipers but then saw the '08's.  Just make sure you use ALL '08 parts.  From the banjo bolt that attaches the brake line to the master cylinder to the bleeders at the rotors.  You will also need 2 of the shorter calioper mount bolts as they are all short.  Ebay has several sets from time to time and it is much cheaper then dealer. I was also able to change to Dot 4 from the Dot 5.  I like the Dot 4 much better.  Don't forget all '08 parts master cylinder to rotors.  Oh yea, I used the Lyndall pads and love them.

I clicked on 03dragonrk trying to find the post by the 100 last post method but came up with 0 posts.  Who ever did it made a J-Peg showing what was needed.  If 03dragonrk did it, maybe he could include the link to the post.  Very worthwhile & a credit to the HDF community!

That was me. Titled - Converted 03RK brakes to 08 Brembo's

Thanks Howard,

I highly respect your opinion and knowage! I was hoping your shop was closer. I will be traveling down from Minnesota the last week of June and base camping for a week in nothern Georgia at a motorcycle only campsite. If you had been close to the northern end of Florada I would have liked to have dropped down to meet you.

Unfortunately I live by the ocean and the keys where I have to fight all of them damned girls in bikinis crossing the street and stopping the flow of traffic while overheating my motor.  Of course you can get a very good price on pecans & Vidalia onions in GA.
