it produces a squealing sound at the rear when brake lever is operated. the disk is straight, the caliper and rotor are aligned, no leak at the calipers. i tried to swap the pads from the front caliper but it still creates the vibrating sound, i also tried swaping the rotors and still it sounds weird when brake levers are operated. what will i do to to stop the squealing sound? is it my frame merida HFS2000 causing the problem, do i have to level the dropout for disk brake?

Did you try adding the caliper infusion fulxtor to the side shaft? that always helps me. Also the squeaking sound is normal you just have to adjust the rotor to spin at a avg. of about 2000rpm Then they wont squeak but they will work the same. your frame sounds like a 92 you should change it to a 98 much better and less likely to create a problem but you dont have one right now.
