About a month ago I used a front wheel paddock stand for the first time everything seemed ok and I left the bike for about 20 minutes. When I got back the bike had toppled over and was resting on some truss we were storing in the container the bike was in it had fallen about 45 deg pivoting on the front wheel.

Since then I have had a variety of problems, when I first rode it after the fall it had a bad vibration through the whole bike, I have got rid of that by slacking the fork pinch bolts on the wheel spindle, slackened the lower fork pinch bolts and pumped the forks up and down to re-centre the forks this helped reduce the vibration to normal but now I have problems with the brakes. The caliper on the right has less clearance than the other side giving problems with the pads centering in the caliper. I tried slackening off the lower pinch bolts on the wheel spindle and hitting the spindle with a rubber mallet which made a difference and I can now fit the pads in but I get horrendous pulsing/grabbing on the discs when I apply the brake, it is really bad at slow speeds.

What should I be looking at, the wheel spindle is one thought, have I twisted a fork leg, a disc what else should I check?
The front wheel has been checked and it is still true only needing 5 grams to balance it.

As usual any hints will be greatly received.

Did the front end twist in the tripple clamps, if so then you will need to straighten the clamps.
The pulsing could be a bent disc may pay to check but I would not expect that degree of damage from what seemed to be a fairly small fall.

Looks like it is fixed, took the wheel off and checked the shaft. There was some pitting which was preventing the fork down tube from sliding on properly. Gave it a rub down with some emery paper and a little persuasion with a wooden handle to just ease it into the correct position and heh! presto all the clearances are back in proportion.

No shudder on the brakes looks like it's all ok, will find out later on in the week when it will get a proper run out.

I'm wondering if you're referring to the cross axel where it goes through the eyelets at the very bottom of the fork?
I made the mistake of attempting to re-assemble mine clean & dry and the axel got stuck going through the second (left) leg. had a very difficult time getting it back out......a lot of metal gaudling from the aluminum against the steel axel. Took about an hour of re-finishing to repair, then LOTS of anti seize compound on both parts when re-assembling.
I had occasion to replace the tire last week & the axel went in and out smoothly.
