floating caliper

[vwar]

While installing floating caliper, disc is placed contacting the pad of piston side? What will happen if placed contacting other side pad?

I don't think I'm understanding the real question. If it's a floating caliper, the caliper will self-center once everything is properly installed and the brakes applied. That assumes all the slide pins and bushings are not seized up and are properly lubricated with a high temperature grease.

Generally the brake rotor (aka disc) is fixed, so the caliper with the piston will be placed over the disc, but the "disc" will not be placed contacting the pad.

Please describe your question with a bit more detail or specifics.

Thanks for your reply rod,ofcourse disc is fixed,while installing caliper,if i keep the gap between disc and static pad (not on piston side) very small,there is no purpose of having sliding motion because when we apply force,the piston moves outwards and rub the disc,the caliper housing remains stationary.shall i do like that?is there any difference in braking performance?

If the caliper is a floating caliper as you mention, then correct, it doesn't matter which side you leave a gap on when installing the caliper and pads, the properly working slide pins will allow the caliper to float and center itself.

Be aware though, after you install all the caliper and pads you should pump the brake pedal to ensure the calipers center and take of the slack between the pads and the rotor. If you don't do this, you will have the sensation of no brakes until you pump the pedal. That's not a good feeling once the vehicle is moving.
