brush flow irregular

My brush suddenly stops when i draw a single stroke.
Most of my brush strokes are irregular in adding mass, meaning when I wish to draw a stroke of clay from a to d, the brush suddenly stops at B.

specs
surface derived from zsphere and zsketch unified skin.
Contains alot of N-poles and E poles due polygroups.
