I was wondering, do they make Brembo rear brakes, and disc, for the XT, and are they worth the money? Has anyone here tried them? What are the part numbers? I tried American Sportbike last night, but they must have had site problems. Thanks,
Tim

The conversion kit uses a rear caliper from a ducati. Its nothing special, but probably better than the goofy single-piston stocker. It also mounts behind the swingarm and is lighter than stock. You use the stock rotor. I haven't tried it on the buell, but have the ducati with the same caliper. It works fine, probably a bit better feel and power than the buell brake. I wish fitting brembo fronts were as easy and inexpensive!

The hidden caliper looks cool but if you just want a rear brake that works change the rear pads to something like SBS. They work a treat with good power and feel. I know I did it on both my 06 and 2010 Ulys.

We have a couple of Brembo options to fit your bike. Either the single piston (Ducati 996 syle) caliper that is hidden behind the swingarm here
http://www.trojan-horse.co.uk/prods/119.html

or there is a 4 piston rear caliper conversion for more power here

http://www.trojan-horse.co.uk/prods/200.html

Both kits are supplied with brackets, pads etc. and spare genuine Brembo pads are available.

Isn't the 996 style caliper two pistons? (one on each side of the rotor)

Just wondering here. if the rear locks up easily with the stock setup, wouldn't a different more powerful brake lockup the same? On my bike once it locks I only skid. Not so satisfying whisper skid.

I found sintered rear SBS pads, as supplied by Trojan to me once, to have good power and feel but they are very hard to find these days. The trick is to find the setup for the balance of how you ride. If you are getting a "wooden" feel from any brakes on a bike you need to do something about it.

I once had a RSVR with all the trick bits on it and the Brembo rear was total rubbish on the road. It was a known issue with that bike.

Some say a rear brake is not needed and they dont use it. Fair enough but if like me you do try a couple of pad sets to see if it helps any. It is a common pad used on many other bikes so there are many to choose from organic and sintered. I am using organic EBCs at the moment and they work for me as I use them to scrub off speed/ balance the bike and on slow road work. And its cheap to do. A Brembo setup is a costly thing to say the least.

Uly_man, when you say wooden do you mean locks up easily? Because Ive got little feel and lots of lockup.
I dont like it and it sure doesn't give me wood

I noticed a big improvement after switching to the Precision Engineering foot levers.
More leverage on the rear brake, more controllability...
Can lock it or take right to the edge of lockup, on dirt.
Also made finding neutral Much easier on the shift side.
I do a Lot of trail braking on dirt roads, back brake working Beautifully for that, for me.
Was looking at the brembo setup before switching levers.
YMMV

The rear brake on my 08 uly has always felt like wood. It barely slows me down. Front brake has always been great, that is why I was wondering if there were any better

What's the matter with just using your boots?

Keep in mind you should always be using both brakes. So the rear is designed to give as much braking as you would need proportional to the load on the rear end.

When you brake, most of the load is transferred forward. If you can't lock up your rear tire in hard braking there is definitely a problem.

I have the brembo 2 piston setup and it works fine. The rear brake really doesn't do much, but it isn't really intended to.

Yes you are of course right. I should read what I type shouldn't I : (

No worries, just wanted to make sure I hadn't gotten it all mixed up. I believe I remember someone saying that the brembo setup saved a considerable amount of weight as well. Has anyone weighed them back to back with all brackets etc to nail down the specific weight savings?

I was thinking of using an anchor.... But my brother doesn't like me calling his BMW an anchor.

The "wooden feel" is like you are using wood on the brake disc. A good brake gives feedback IE you can tell how much braking you are using/ need and thus how much to apply at any one point.

The key with all things bike is feedback. It is what makes a bike so special and the XB so very good at what it does.
