Front Brake Rubs A Bit

The pads should retract slightly from the disc when the lever is released, the slave cylinder seals and seal grooves are profiled / designed to give a specific amount of retraction.

Worn or ageing seals or build up of corrosion in the seal grooves or on the piston are common causes of insufficient retraction and pads rubbing on disc.

There is no adjustment, typical of hydraulic brakes is that it's self adjusting for pad wear

You could try pulling the caliper and pushing the Pistons back in to see if they are stuck in the caliper

Bear in mind the fluid goes back to the master, it may overfill so don't use a clamp or you could blow up the reservoir

Also make sure your wheel brgs are not the culprit, even a tight axle can cause drag
