I took brake pads off, but I can't get brake cylinder pushed in. Can somebody help me?

Are you talking about the piston in the caliper? If so, open bleeder screw and compress piston. If piston does not move freely, replace caliper.

how to disconnect emergency brake cable from caliper?

how to disconnect parking brake cable from caliper?

are you talking about the rear disc brakes? If so you have to screw the piston into the caliper to get it in.

Do you have a manual?

no I dont

<drdisque> what do you mean: screw the piston into the caliper ?

To compress the brake piston on the rear disc brake caliper, the piston needs to be screwed back in. There are special tools available to do this, I suggest borrowing the kit from your local auto parts store chain. The little cubes that can attach to a 3/8" drive ratchet wrench are not worth the trouble.

On the rear brake piston there will be a couple of notches on the surface. There will be corresponding tabs on inboard brake pad. The tabs must align with the nothches on the piston. Similar to the brake pad tabs, there will be tabs on the tool to thread the piston back to the compressed position.

The reason for the threaded piston and the notches and tabs has to do with the cable activated parking brake system. When the parking brake is engaged, it rotates a lever which in turn presses on a spring-loaded push rod. The push rod mechanically activates the parking brake. At the same time though, activating the parking brake causes the rear brakes to "self adjust." To release the self adjustment, you must thread the piston back to the compressed position.
