Well i just replaced my master cylinder clutch and would have loved for more indepth information and some pictures. So here are pictues and step by step information to go along with it.
1. First of this will be alot easier if you take out your front drive seat. Unplug battery as well.
2. start by removing the panal under your steering wheel.
3. Remove Hood release cable and your diagnostic cable.
4. You are going to need to remove your starter safty switch (black)
5. Continue by removing these 3 things
1- Speed control deactivation switch (Green) Turn left and lift small clip.
2- Stop lamp switch (Grey) turn right and lift clip
3- Clutch Position Switch (Red) turn left and lift clip.
They do not need to come off in any order what ever is easiest for you. When removed you will need to put these cables in a safe spot. I put them up by my steering wheel.
6. You will now need to remove both bolts that hold your master cylinder clutch in place. they are 10mm. (note do not pull master cylinder clutch out of compartment until you have drained most of your fluid out so you dont get a pond in your car.
7. after you take those bolts out you will now take off your clutch pedal and spring. (in picture the master cylinder is still on there)
8. You will now remove the pedal assembly so when you put your master clutch cylinder back on you do not snap the white rod like i did :/. There are 4 bolts.
9. In the engine compartment you are going to need to take out your battery and move your fuse box a little atleast i did on my 2004 focus.
10. Drain your clutch/brake fluid. you can use a turkey baster in this occasion.
11. When your fuse box is out of the way you will be able to see where the green rods come through into your engine bay as seen below.
12.There are small butterfly clips on the green parts you can use a small ice pick in order for you to get them out easily. be careful not to loose them there are new ones with your new part but its nice to know you have an extra one if you happen to loose one. (cover the lines with paper towel you do not want to get dirt in them!)
13. Now remove previous clutch master cylinder and install the new one in the previous order. connect all the lines and refill brake/ clutch fluid. Use dot 3 brake fluid. picked it up for about 5 bucks at my local autozone.
14. Heres the rough part it took me a good 45 minutes to find the bleed plug for my clutch you are going to need to bleed your clutch, and maybe your breaks. I did not need to bleed my brakes i left just enough in the reservoir to not need to do that.
You will need to pump your clutch multiple times. YOU WILL NEED TO PEOPLE to bleed your clutch and or brakes.
