Hope hydraulic disc brakes are valued for their reliability in nasty weather, but one pitfall they have, common to all disc brakes, is a tendency to rub. A telltale sign of rubbing is a whirring noise emanating from the brakes when riding. Rubbing can cause brake pads to wear down faster than usual. A solution to this problem is to realign the brake pads on the rotor. While not an ideal remedy for brake pad rubbing, this can be a stopgap solution.

Remove the affected wheel from your bike by flipping open the quick-release lever and pulling the wheel out of the bike's dropout. If you are removing the rear wheel, try shifting to the highest gear (the smallest cog on the rear cassette) to make removal a bit easier.
Insert a tire lever into the bottom of the caliper against the brake pads, which is the device that clamps over the rotor. Gently rock the lever back and forth against the pads until they are pushed all the way back into the caliper.
Place the wheel back on the bike. Pick your bike up off the ground and give the wheel a spin. As the wheel spins, squeeze the brake lever repeatedly. You will feel it pump up in power as the brake pads push back toward the rotor. Squeeze it until it stops the wheel; repeat the process until the brake lever maintains a firm feel for several squeezes.
Tips and warnings
- If you don't have a tire lever, you can use a flat screwdriver to push the pads back in. The key is to not harm the pads by gouging them with whatever implement you use.
