the part in image 1 is removed (simply pulls out) and replaced by part in image 2
use caution as the shaft for the part in image 1 can break and will be difficult to remove,

be sure to adjust modulator pressure before you intall the white cap, when instaled it only allows for minimal adjustment, and can damage the modulator if not properly removed
