If I'm correct you're having trouble retracting the piston on the caliper. If I'm not then don't read anymore. You need to turn the piston clockwise while applying pressure against the piston. The easiest way is in a large vise with a socket against the piston while using channel locks to turn the piston. This is if you don't rent the special tool for this specific task. Don't feel bad I got the answer the same way you did. good luck
bad piston rings or bad valve seals. valve seals are easy but time consuming to replace, while piston rings mean a total engine rebuild. sometimes, you can remove the sump, and get the pistons out from underneath.
A Caliper Reset Tool is a tool used to 'reset' the brake caliper piston on calipers with an integral handbrake system. The tool spins the piston while applying pressure to compress it enough to replace the old pads with newer thicker ones.
the piston needs to be turned counter clock wise while compressing the piston
There is a special tool that one needs to accomplish this task. It turns the piston while pressing the same piston into the caliper body. Try www.germanautoparts.com to purchase same. Do not try to do it without this tool, you will damage the caliper and it will cost you $$$$$ to replace.
When the piston goes up the heat temperature decreases while when the piston is down the heat temperature is increases.
You've gotta use a compression sleeve to keep the piston rings in while depressing the piston.

to remove the piston, you need to remove the carb and intake. You will then remove the 4 acorn nuts from the top of the cylinder head and the 2 bolts on the left side of the head. You can then remove the cylinder head and slide the cylinder up off of the 4 studs while insuring the piston is sliding out the bottom of the cylinder. Also take care in making sure the piston and connecting rod do drop against the studs as it exits the cylinder. To replace the piston, simply remove the cir-clip from either end of the recessed area in either side of the piston and you should be able to push the wrist pin from the connescting rod and piston. It is recommended that you replacee the cir-clip with a new one upon reassembly. And of course, you should reassemble with new head and cylinder-to-block gaskets.
Remove the spark plugs, dump in some 2 cycle oil over each piston, replace the spark plugs, turn the engine over 1 or 2 times, Let the Jet Ski stand for a while.
To push the piston in you need a special tool. The rear disk brakes on this car screw in. So you have to turn them to the left while pushing in and this requires a special tool to fit the piston.
You have to have a air compressor to do it. Take an air gun and insert it in the hole on the caliper were the brake line goes to it. Then take the piston in one hand and start it in the caliper while you are blowing air into it and the air will push the rubber boot out around the piston as you push the piston in. It is alittle trickey, But that's how you do it.
