What servo is that? Sure looks like itís stuck in. There is usually a seal on that piston but sometimes it is removed to give more apply area.
Yes the R servo refers to the piston size. Looking at yours , looks like the piston is running in the case bore? If so it might already be an R.
If so it might be a Sonnax. If so that large land on the piston needs machining. Every one Iíve ever fitted needed machining. It might be stuck in the bore ?
If it is a Sonnax they come with light springs.
