This was getting buried in the EBC Greenstuff thread, so I started a thread for those that wanted to know how a rear pad change is done.
Below are the steps I followed to perform the install. I\\\'ve included what the Service Manual states and added some of my own findings.
1. Ensure the parking brake is not engaged, block front wheels off with some bricks, jack up the car, support with jack stands, remove the wheel.
2. Remove the cap from the caliper bolt cover to get access to the caliper bolt - both top and bottom.
3. Excuse the crappy picture, but the caliper bolt is a #7 Hex head
4. Loosen and remove the caliper bolts (socket wrench works best here) and take note of which bolt belongs on the top and bottom.
5. Remove the retainer spring (item 4 in the 1st pic) - a set of pliers works best here.
6. Lift the caliper up - you will now have access to the pads.
7. Remove the outer pad from the caliper mounting bracket (it just slides right out).
8. The inner pad may be on the caliper or it may be on the mounting bracket. If it is stuck to the caliper, pull down on the pad (it is attached via spring clips). If it is on the mounting bracket, remove just like the outer pad by sliding it out.
9. Now you will have to get the piston back in to clear the new pads. This is done via a combination of turning and pushing.
10. Open the brake master cylinder reservoir cover to relieve the pressure in the system.
11. Using a set of needle nose pliers:
Set the needle nose tips into the piston grooves:
and turn clockwise while pushing on the piston. It may take some force, so if you notice the piston not retracting, push harder.
Be careful the pliers don\\\'t slip and cut the rubber piston boot
12. Once the piston is compressed, tighten the cover on the master cylinder, and follow step 4 in the 4th pic above.
Align the spring clips on the back of the pad to the piston and push up
the pad should snap into place onto the piston.
13. Slide the new outer pad into the mounting bracket.
14. Apply some \"anti-squeal\" to the outer pad (I used some Permatex stuff bought at Canadian Tire):
and reinstall the caliper onto the bracket (placing it over the outer pad):
15. Replace the retaining clip.
16. Replace the top and bottom caliper bolts. Hand thread them first - you may have to move the caliper until the bolts catch. Tighten the bolts to 19-22 ft-lbs.
17. Replace the cap on the caliper bolt cover.
18. Reinstall the wheel, tighten the lugs, lower the car, torque the lugs to ~80ft-lbs.
19. If you live in a house with a tiny garage that can only do one wheel at a time (like me), pump the brake pedal a few times before and after you start the car. This includes when the other side is complete - pump before moving the car.
20. Repeat the steps on the next side.
Note: the Service Manual states to remove the parking brake cable from the caliper; this is not necessary.
After all is said and done, EBC advises to drive gently for the first few hundred kms. But before doing so, they give an initial bedding procedure as follows (find a clear stretch of road where this can be done):
* get the car up to ~60km/h and brake gently to a stop.
* repeat approx. 5 times with applying more pressure (i.e. stopping over a shorter distance) each stop with approx. one minute intervals in between.
Hope this helps 8)
the following pics show the wear on the stock pads after 56,800kms. I was actually surprised at how much was left after 56.8K with >90% highway driving:
Driver\'s side outer pad
Driver\'s side inner pad
Rear pads
Needless to say, I\'m glad I changed them.
