Adjustment problems alone do not cause hydraulic brakes to pull. Look for a collapsed flex line on the side opposite the pull. If it's pulling toward the driver's side, check out the flex line to the passenger-side wheel. Something is keeping the pressure from applying the brake opposite the direction of pull. A sticky wheel cylinder on the passenger's side brake will cause a pull to the other side, or you might have oil grease, or brake fluid on the side that's doing the pulling, resulting in a grab. Were the drums machined or replaced during the brake job? The rust-preventive coating on a new brake drum will penetrate the shoes and cause a grab unless it was washed off with a solvent like brake cleaner or alcohol before the drum was installed.
