I recently installed the 5mm rotor and hardware from Erik Buell Racing. It has probably 800-900 street miles and two track days. I noticed right away that the front wheel will only turn 2 revolutions before it stops. To me I think it should spin more freely. I have gone over the install process several times and everything seems correct. I will say I do alot of trail braking on the track. I also installed a new set of EBC pads because I was having issues with the lever going half way and being mussy. So I ran two track days since then not knowing what was going on. I just figured it was the pads. But after talking with a few people they told to replace the original brake fluid. So I may have been working them a little harder. Here is a picture. What do you guys think? The only 1125r rotor that looks like mine that I have seen was on Higbee's bike.  | ||

Can't say much based on looking at your picture, but it doesn't look odd, either. In fact, my setup is damn near identical and looks just like yours with one track day and 3k of street miles on it. Maybe Jdugger will chime in with a picture of his rotor. THAT rotor looks like it's been used...hard. That being said, my setup (5 mm finned rotor, Erik Buell Racing hardware, EBC HH street pads, ZTL2, and GSXR1000 radial m/c) spins freely. check your pads for dragging...pads, piston seals, m/c, etc. You can also check the rotor for run out. | ||

It looks like the pads are dragging. What could I have messed up with the install? | ||

I found the ZTL2 pads to be harder to change than the ZLT1. My procedure is to insert the outer pad, then partially insert the pin. Once the outer pad and pin are in place, I install the inside pad and then slide the pin fully into place, making sure the pads don't move and skew. Doing one pad at a time ensures the pads are fully seated and parallel, which made installing back on the rotor MUCH easier. I'd like to think that even if this wasn't done, the rotor would self align the pads and all would be well - at least, that is how it SHOULD be designed. However, I found reinstalling without doing this procedure made my life suck a little more. So, I'd check that out - knowing that this probably ISN'T the problem - just to make sure. Also check your pistons when the caliper is off the rotor to make sure none aren't fully retracting. These should be free to move with no binding and minimal stiction. | ||

What EBC pads are you using ? The EPFA pads can't take the heat this brake system generates. They break down and literally crumble. I've gone thru the four sets I initially purchased and won't use them again. I get one day from a set and by the third session you can hardly turn the wheel by hand, from so much pad material deposited on the rotor. Frankly, the stock street pads are better. They stop as well and there is no drag. They stll only last a day, though. Now using Vesrah pads, much better. All that said, your rotor hasn't been hot at all, yet............ | ||

The EBC extreme pro pads are the track pads. I know it had better movement with the stock rotor and Erik Buell Racing pads. | ||

At last someone with the exact same problem as me, started when I fitted braking pads, changed to ebc, still dragging, I only get half a turn, changed fluid numerous time Inc upgrading to dot5.1. Then fitted ebr finned rotor and ebr uprated fitting kit. Still the same, fitted a cr red caliper, still the dragging, Installed a gsxr mc and still I have the dragging. Only thing left to try is changing the line which I will be doing soon  | ||

Track pads ? Not quite........ Here's what they look like after only 120 miles:   And here's a set of oem pads. Same mileage, same abuse. They're worn out, but they're not coming apart and there was zero drag.  | ||

Ysracer, you're using Vesrah pads on your 1125? I'm a big fan of the SRJL-17 compound but last time I checked, Vesrah didn't have any pads for our bikes. What compound are you using and where did you buy them? | ||
| Rsh |
These are the Vesrah pads listed: Front Metal/Organic VD-9038JL | ||

Just took my EBC pads out. And they are slowly falling apart. Not quite as bad as YSRACER but getting there. I can't beleive it. I was going to do a track day in a week but I am back to stock pads. I have a set of Erik Buell Racing pads that are not worn out that I can use but they have been used pretty good. | ||

i had the same problem with dragging and overheating with fade until i noticed that when i put a new caliper on the pistons were fully retracted and when i pumped up the M/C to seat the pads to the disc after tightening the caliper the problem disappeared. anytime i change front rim or brake pads now the pistons are fully retracted for the initial seating to the disc. no more problem. hope it works for you! tim | ||

Pull the master cylinder lid. Remove the brake caliper bolts so you can wedge the caliper "crooked" against the rotor, pushing the pistons (and pads) into a more retracted position. Check your brake fluid level. Adjust as needed. Tighten the cover. Pump up the brakes by hand. Go for a ride. Should fix ya  | ||

I get a fair bit of brake drag, too. After you have run 2-3 sets of pads, buy the caliper rebuild kit from your dealer or Erik Buell Racing and clean/rebuild your caliper. Makes a nice difference. | ||

This is the worst EBC pad of the four.  I may put it back in for my track day on the 21st of this month. What do you guys think? I think they will be ok for the track but I will take them out when I put the bike back together for the street. I will be buying the ebr pads this winter. I beat the snot out of those pads for 4000 miles and 7 track days,and they still could be used. | ||

How much time and money do you track day riders/racer spend on changing pads and rotors? Until there's a ZTL3, through a dual disk on put new RJL pads ($110)and forget about it next spring. Easy to do if you have any mechanical know how... When I'm grabbing a hand full of break all day long into turn 1 with the rear in the air I'm smiling not showing my best Oh shit face... I'm not bashing, please keep in my mind I'm a fan of the ZTL it's one of the 4 reasons I originally bought the bike... I have confidence ERB will come out with a ZTL3, they change there rotor and pads every session... 1. Made 2 hours away 2. Chassis 3. V-twin 4. ZTL  | ||

Buell101 im on the look out for a front end, have been for a while, what year R1 front end is that ? Also once its all installed with the custom yokes how do the clip-ons with radial MC clear the fairing frame when manouvering at low speeds. | ||
| White79bu |
I took the bike back apart and full compressed the pistons. I then installed the EBC pads. So far the wheel spins much better than it did before. I hope that fixes it. | ||
| Avalaugh |
Well i have bought an R1 front end, just got to get it fitted, hopefully that will sort it. | ||

This guy is might be using the STANDARD FA454/4HH Pad's ! And NOT the EPFA454/4HH EBC Extreme Pro Ceramic Sintered pad's. I have a bunch of ASRA ThunderBike races using them, for over 2 year's now ( like Dan Balansky from Hal's H-D ) and they work well. It will be INTERESTING to find out what's REALLY Going On ! Std. FA454/4HH HH or Extreme Pro EPFA454/4HH. However, I am not so crazy as to think that this might not be an EBC Brakes Product/ Compound Issue. It has happened a few time in the past, in the last 15 year's or so, for EBC, to have a compound batch issue, so it is a remote possibility. As an EBC Brakes USA Customer Good Will & PR Jester, I will replace, at No Charge, anyone's EBC Buell EPFA454/4HH's pad's that may have worn out quickly, or had the pad friction compact edge's crumble a bit. E-mail me at mrsi2@comcast.net for more info... I do know that our EPFA-HH Extreme Pro Pad's Out Perform the Brand V RJL & Super RJL Compound Pad's. Our own in-house Brake Dyno's have proven this !

Thanks for the post, Garry. Very cool to jump right on this. I hadn't seen this thread prior, a badwebber just pointed it out to me today. I talked to our rep at Van Leeuwen, who contacted Garry, who didn't waste any time responding. Al | ||

Nice to see direct support from the vendor here.  to EBC! | ||

Very cool! I know where my next pads will come from (and through which retailer!) |
