This one is simple but I'm gonna post it since I have the pictures. 1. First level the bike and check the fluid levels, first on the handle bars.  You can see that its level and there is a small bubble at the top of the window, this is normal, if you need to add any just unscrew the two tops screws and add a little dot 4 brake fluid and check all the fittings for leaks. Do this when the bike is level and upright, if not you'll leak dot 4 fluid all over the place. 2. do the same for the rear brake resevoir, mine is on the right side, under the seat.  this one is easier than the front. 3. check out the brake pads!   Looking at the pics I need to use my rear brake more, but neither pads need replacing at this time. | ||

Hi I have been searching the forum to see if there was an answer to my current question of brake judder. I have an 05 model year Firebolt xb12R I had been worried that I had a warped front rotor - but reading the posts see that this may not be the case. Below a picture - be interested on what folks recommend as a fix.  skri | ||

The brake pads leave deposits causing the pulsing. There are a couple ways to remove them. You can scrub the heck out of it with a scotch-brite pad or buy a rotor hone that can be used on a cordless drill. If you plan on removing the front rotor consider replacing the mounting hardware. | ||

Manually clean rotor faces, edges, holes; plus pad contact surfaces; both are contaminated. An XB quirk; mine did it, too. Changed brake pads (Lyndall). Practicing at not holding-at-stop using warm-hot brake(s). So far, so good. Looks like some grooves in rotor/pad, too. I accept uniform grooves: grinding rotor removes steel/mass, diminishing heat capacity. | ||

Hi Aptbldr, Many thanks for prompt advice. I am stuck in Houston due to the Icelandic volcano suspending flights back home to London, so think i will try and get some Lyndall pads whilst I am here. rgds, skri ps like the colour of your bike - snap mine looks just the same | ||

Aptbldr did you go with organic or sintered HH pads? | ||

After speaking to Al at American Sportsbikes, I have decided to go for the #9060 Lyndall Gold+ Carbon Kevlar and not the sintered version. I'll let you know how they feel after I fit them (could be several weeks). Fade has not been an issue to date but deposits and brake judder / shudder have been a pain, so here’s hoping that I have made a good choice. Al was confident that the pads will clean up the rotors providing I bed in properly. I am fitting some sintered EBC HH pads to my RS Sprint so it will be interesting to compare the feel. |
