When I bought the bike a month ago the rear pads were down to almost nothing. Had new pads put on 3 weeks ago and the brake still sucks. Is it normal? Any fixes?
Thanks...

The rear brake is more of a hill-holder than anything else - that's normal. I've used stock and Lyndall Gold, and while neither are great, the Ferodo sintered pads give marginally better performance with the stock rear rotor.

It's just weak. I plan on changing to either the Bembro or Nissin w/ 4 pistons. They aren't cheap - $400+. May be able to find one on the bay for less?

The rear brake does little more then slow you down very slightly. I would bet I couldn't lock it if I stood on the brake pedal (all 260 lbs of me).

It is all in how ya bleed her.

use the handle of a hammer and rap on the caliper while bleeding. The releases the bubbles that get trapped in the nooks and crannies of the upper most part of the caliper. I even go as far as putting a piece of metal between the pads and bleed her up-side-down...

It took me awhile, but now the rear brake feels just right. It's certainly powerful enough, but it does have a wooden feel.

All other rear brakes seem too sensitive now.

The IDEA is to have a REAR BRAKE that slows you down without LOCKING up the REAR WHEEL !!!

I believe the numbers are 70/30 anyway aren't they?
If so there's not much expected of the rear brake to begin with. I believe mine was set wrong when I bought it and it locked up on me a couple of times in the first couple of months.

Scared the bejibbies out of me.

I didn't say I wanted to lock it up, after 27 yrs of riding, I've never locked the rear brake in a panic situation (knock on wood), but on every other bike I've ridden (& that has been literally 100's) the rear brake was at least able to be locked (excl. ABS models).
The point is - I could slow the bike down faster by dragging my feet then using the rear brake.

There is something wrong with your rear brake then. I can lock my rear at 40-45mph just using the rear brake (never tried to lock it at a higher speed).

What pads did you use when you replaced the old one?

Did you change the brake fluid too? This needs to be done more frequently than you'd think.

Bleed enough to totally replace the brake fluid in the entire system... and make sure to use the proper DOT classification (on the reservoir cap).

It'll probably never be as sensitive as you'd like, but it should be better than Flinstone brakes.

I have recently done the rear brake with a stainless line (with an XB banjo/brake light switch) and bled using a harbor freight power bleeder. I can lock the rear brake at speed, but it still takes lots of effort to do it.

It sounds like you've got the standard rear brake setup.

Some like it, some don't. I've had a few incidents on other bikes where I locked the rear so I really like this Buell design better. Buell has some of the best 60 to 0 stop times of the time (they were top 10 in Motorcycle Consumer News) so I don't have any complaints.

But if you don't like it you can either get a different caliper or master cylinder to apply more pressure on the rear disk.

Whos - where did you find a SS rear line? I have scoured the net and can't find one for the X1's. Thanx

I made the line myself from earls components. I used -4 (iirc) line thats intended to be used with brakes, its stainless with a plastic coating and looks like regular stainless line, It took about 28" of line if I recall to match exactly the path of the stock line. I also used 2 30 degree stainless banjo fittings. And the XB bolt.

I'll take a picture when I get the chance.
