I need the brush size for the write-on effect to go larger than 50. Any solutions?
Use the normal paint tools.
The After Effects CC (12.2) update increases the maximum size of the brush for the Write-on effect and Stroke effect to 200 pixels (from the previous maximum of 50 pixels).
only in cc update?
