I would suggest that you follow the very detailed explanation in the Haynes Manual.
I take it that you have not found what you are looking for on this Forum?
If all else fails, start by slackening off the hand brake cable adjusters.
Use axle stands to support the car - Do NOT work on a car supported only by a jack.
Work on one side at a time, making notes/sketches and/or taking photographs as you go.
By doing this, should you still have any problems, there is always the opposite side to look at for inspiration.
