I saw your other post asking about used rotors and calipers... there is no way you damaged anything using your brakes. Worse case scenario you deposited a heavier layer of pad residue on the rotors and now the “feel” is different. I would put the bike up on stands, and clean the rotors with some fine sand paper and then wipe them down with either brake cleaner or acetone to remove any deposits. If you want to be really thorough, you could also remove the calipers (don’t disconnect the brake lines!) and then remove the brake pads, and finally clean the calipers thoroughly with a mild dish detergent, distilled water, and a tooth brush; you should be doing that at least a couple times per year - more frequently if you start doing track days. I get out a bucket, hold the caliper over it, and use a spray bottle with the soap and water mix and spray it on the caliper. Then start scrubbing with the toothbrush and follow with another spray bottle with straight distilled water. All of this dirty liquid ending up in your bucket. I like to use some compressed air to help dry the calipers and then reassemble.
Finally, the way you retighten your caliper bolts is again, with the bike still on the stands, put the calipers on and only tighten the caliper bolts finger-tight. Spin the front wheel with one hand, and then grab the front brakes with the other hand and repeat a couple times. On the last “spin and grab” do not release the brake lever, then use your wrench to tighten the caliper bolts securely. Release the brake lever and use a torque wrench to set the caliper bolts to 34 N-m. All this was to properly align the brake pads with the rotors.
All of this will allow you to inspect and regain confidence that things are okay.
