If you haven't done the job yet take several digi photo of the cylinder in place before removing it so you know which way round the anti rattle spring goes. The book photo is not very clear on this.
Try your local library for motor book save's buying one for one off job.
Tip: to collapse the piston to get the new pads in use a carpenters G clamp it's perfect for the job that's how I did mine.
