Since I’ve done the front brakes on the Jetta again, I decided that I might as well go ahead and replace the rears as well. I probably could have gotten away with just replacing the pads but I went for the whole shebang since the rotors did not cost me too much more and I was there anyway.
Safety first, lift the rear of the car and get a jack stand under the side you are working on. I usually break the lugs before I lift the wheel off the ground so that it does not turn while in the air.
Remove the wheel and expose the rear brakes.
Remove the caliper slide bolts. I believe that they are 13mm bolts that hold the caliper to the mounting bracket. I did this backwards on the first side but got it right the second time around. You will need to keep the one square nut from turning in order to remove the bolts. I used needle nose pliers, I’m sure there is a wrench that fits……
Once you have these bolts off, you can take out the old brake pads.
For this wonderful German car, you will need to purchase new streatch bolts for the rear calipers. They are single use bolts and once you remove them they will no longer hold. Believe me, I know this from experience. Not only are they single use but they required a special socket to remove. It’s a 12 point triple square socket in 14mm sizing.
Remove those two bolts, if you are just replacing pads, don’t touch them!
You will need to push the piston back into its bore in order to replace the brake pads. This is not like the fronts where you just use a giant C-clamp, you will need a special tool in order to accomplish this. I actually went out and purchased this tool by Schwaben to make my life easier, but have pulled this off with needle nose pliers and other tools. You just need to find a way to turn it back without damaging it.
What was I thinking?! I took no pictures of the rotors that I took off. It’s not really a big deal, you can reference the Front brake post to see how to get the rotors off, it is the same procedure. You take out the star screw, bang the rotor with a ball-peen hammer, and it pops off.
Once the rotor has popped off, you can replace it by lining up the hold screw, screwing it in, and……that’s it!
When the rotor has been replaced, it is time to start putting the brakes back together. Make sure that you use the supplied hardware and replace the old stuff that is currently on there. You may even want to use a little grease on the new hardware for easy sliding. I chose not to this time….
The hardware has been replaced, now mount the brake pad carrier. Use your new streatch bolts and mount that carrier! I’m sure there’s some kind of torque spec but I just made it super tight since my torque wrench is broken.
Put the new pads in the carrier. They should slide right in.
Now mount the caliper. Slide it over the new pads and put the two bolts that hold it in place on. I use a little bit of anti-seize on these bolts so that I can remove them again later.
Completely assembled rear brakes
That’s it! Put the wheel back on and do the recommended break in procedure as mentioned on your brake pads.
