Sticking brake calipers. This can be caused by moisture in the brake fluid which will cause the calipers to rust. Replace the calibers and replace all the brake fluid. It can also be caused by driving with your foot on the brake.
No need to rotate the front caliper pistons as you compress the front calipers. That process is only for the rear calipers because of the parking brake mechanism.
have you tried the proportioning valve. sometimes dirt will get in there and clog the returns.
It is time to replace the brake calipers when they begin sticking closed or do not close all the way. You might also have a caliper that locks completely which needs to be replaced.
Check for sticking calipers.

The brake calipers can be the same the front calipers on turbo cars is normally bigger as up to 90% of your braking force is on the front brakes but the back ones are somtimes bigger not always
Your bike brakes may be sticking due to dirt, debris, or misalignment. To fix this issue, you can try cleaning the brake pads and calipers, adjusting the brake cable tension, or realigning the brake calipers. If the problem persists, it may be best to take your bike to a professional for further inspection and repair.
Normally a front brake issue, could be an alignment, suspension or tire issue. Check that all suspension parts are in good condition and all connections are tight and that there's no obvious misalignment or disproportionate wear of the front tires. Next, check that front left caliper is not sticking closed and that front right caliper is not sticking open. If calipers are working, try replacing the brake hoses to the calipers, normally the opposite side to the direction it's pulling will be collapsed causing the 'offside' caliper to not close.
A rubber burning smell and smoke near your two front tires could be the result of sticking calipers. The brake line could also be the cause of the burning smell.
Could be cheap brake pads.
