A packer installation system includes a pipe, a packer that is secured to the pipe at a first axial position along the pipe, and a brush assembly that is secured to the pipe at a second axial position. The brush assembly includes brushes that are adjustable between a first configuration in which the brushes extend radially from the pipe by a first distance and a second configuration in which the brushes extend radially from the pipe by a second distance that is greater than the first distance.
