Spud, your way too fast with the answers and help, much appreciated, thanks.
I'll send a note CSC also and ask what they may know about brake up grades. Being here in Iloilo City this stuff isn't available, I'll have to order them from the US and have shipped to me so I need to be sure I'm getting the correct parts, returning stuff from here just isn't piratical and I have a few parts (for a different bike) on the shelf collecting dust.

Pulsing in front brake?
While we wait for a better front pad, do any other RX3 owners experience a pulsing in their front brake? Been that way from new on mine, thought it might work itself out once the pads seated themselves, but after 2000 miles, it's still there. Feels a bit like the brake grabs then releases, grabs and releases, etc as the wheel turns. I realize this is normally an indication of a warped rotor, but I would not have expected that on a new bike. I plan to check it out.

Brie pad
My front brake is pulsating, so I need to contact Ryan to ask for a replacement.
Does the front brake pad need to be replaced at the same time? Wouldn't the Brake pad also have uneven wear due to the faulty rotor? What is the recommended torque for the bolts? Why would I need to replace the bolts? Thanks Dave

Installing the rotor bolts is not a problem. The problem arises while trying to remove the rotor bolts. The bolts are bathed in loctite at the factory, and probably installed with an impact driver. Therefore, it is very easy to strip the Allen key head, which can make the bolt very difficult, or impossible to remove without machine work.
Remove the bolts slowly, and with great caution, taking care not to strip the head. It is recommended to heat very troublesome bolts with a propane torch. After you successfully remove the bolts the first time, subsequent installation and removal of the bolts is an easy process.

A number of us have reported brake pulsation. Has anybody made the run-out measurements with dail yet? I can feel the pedal of the rotors just be for coming to a hard stop but no pulsing at speed.
I really do need to find a more aggressive pad, I'm worried my ham fisted braking technique I've developed to stop the RX in a reasonable distance will end in desaster the first time a panic breaking situation arises in my Sprint. |

I didn't measure run-out with a dial indicator. However, I did measure the thickness of my old brake rotor with a micrometer, and I noticed numerous variances in thickness.
After doing some research, I concluded the front brake rotor has the same dimensions as many KTM brake rotors. The only difference is the RX3 brake rotor has larger bolt holes. If one wanted to insert helicoils in the front hub to accept smaller bolts, I'm sure he could switch over to the KTM brake rotor.

I think you are correct, Pete. Unfortunately, I don't own a drill press, neither do I own good drill bits for cutting hard steel.

Rather than drill the brake rotors every time, I would rather stick with Zongshen rotors, or install helicoils.

Spud, I measured thickness on my pulsing front rotor also and found it to be about .005/in variance. Rear one was within .001". Bought a new rotor and surface ground the old one best I could and it made it usable with a very mini pulse feel to it. Keeping the new rotor for later. rj
