Hi, Anonymous your bike starts great when cold but once it reaches operating temperature and the engine is shut off for a few minutes then you try to restart it and it will turn over but will not fire or it doesn't do anything, the usual suspects are:
1. When electronics get hot they build up resistance then stop working. It might be an ignition coil, stator, CDI unit etc. First, you must find out if the spark dies out. When the bike won't start, pull a plug wire off, stick a new spark plug in the end and ground the threads on bare metal while someone cranks the engine over. You should see a nice big blue spark between the spark plug gap. Incorrect spark plug gap will cause or contribute to a no start when hot issue.
2. Fuel Tuners have been known to cause this type of problem, disconnect it and see if resolves the issue.
3. Any engine management sensor could be faulty especially the ones that monitor temperature.
4. Gas cap not venting properly, improperly routed fuel lines they must always go down from the gas tank to the carburetor never in any kind of a loop this will cause a vapor lock. Clogged, bent, kinked, pinched or restricted carburetor vent lines will do the same.
5. Overhead camshaft valves adjusted too tight when cold, this will cause loss of compression when hot, except for pushrod engines they usually get looser when hot.

Install a new spark plug; NGK DPR9EA-9. Be sure the battery is fully charged. Drain the carb to remove any condensation in the float bowl. Use the choke and throttle sparingly to avoid flooding. Get the piston going upward to TDC compression. Now gently push the piston just past TDC so it will be heading downward. Now give the kick lever a good strong kick. Repeat the process as needed.

make sure it is not overfull with oil(sometimes a flooding carb can put fuel into the sump) or it may be compression blowing past the rings and pressurising the sump,
a small amount can sometimes be normal on very rough terrain

Yes, first check with your local bike dismantler then check the Web through Google if you can't find any in your local area else go to eBay under parts.

You didn't specify front or rear so I will hit both.
Start with the front. Refer to this diagram:
http://216.37.204.203/Suzuki_OEM/SuzukiDB.asp?Type=13&A=91&B=43
Unbolt bracket 13 from the fork leg, then remove the 2 brake pad retaining pins #12. The brake pads can then be removed. You will have to compress the spring #5 when putting the pads back in to be able to reinstall the pins #12.
On the rear, refer to this page:
http://216.37.204.203/Suzuki_OEM/SuzukiDB.asp?Type=13&A=91&B=49
You have one of two choices, either remove the rear wheel so you can drop the pads out by removing the brake pad retaining pins #13 or unscrew #8 from the caliper bracket then remove the caliper.
