Brake Piston problem

[Sweet Ride]

I have a 99 400ex and i started changing the brake pads. The only problem is that i cant get the piston to push back in. I have tried every thing posted. It wont budge even with C clamps. Any Ideas? Thanks

I had the same problem,
tear those calipers down while your at it, there actually very simple! Tear them down and bleed the brakes and your brokes will be like new and it will correct your problem!

i have the caliper completely off but i get the part where you use a hex key to open. Do i have to get that out 2. Thanks
