GV250 How To: Change The Brake Pads
What you will need:
- 12MM Wrench
- #2 Phillips Head Screwdriver
- 5MM Allen Wrench
- Replacement Pads
- Hyosung: 59301HG5100
- DP # DP111
- EBC # FA86
- Honda # 45105-KR3-405 *
- C-Clamp - might need, might not
* These are what I used.First remove the caliper from the forks using a 12MM wrench. These are going to be very tight so be careful. The bigger the wrench the better.

Slide the caliper towards the back of the bike and separate from the retainer plate.

Using a #2 Phillips head screwdriver, remove the two set screws. Be careful, they are tight and you don't want to strip them.

Using a 5MM Allen wrench, back out the pad pins that are under the set screws.

Remove the brake pads. Note the spring. When inserting the new pads you will have to push down to compress the spring so you can run the pins through.

Here's how it should look with the new pads in place.

Reverse the the steps to re-install the caliper (insert Allen pins, insert set screws, put caliper back on retainer plate, put caliper on wheel, bolt to fork) and your done.
EDIT: Don't forget to pump your brake lever several times after changing the pads. Because the caliper was depressed, you will have no brakes for the first couple of pulls until the caliper is back in position.
