🔧 Repair Overview
Brake Pad Replacement is one of the most common repairs for 2012 Toyota Yaris. This repair involves replacing the damaged brakes component with a new or refurbished part. The process typically takes 1-2 hours and requires moderate skill level.
What You'll Need
- Replacement brakes part (OEM or aftermarket)
- Precision screwdriver set (Phillips #000 or pentalobe)
- Opening tools (plastic spudger, suction cup)
- Adhesive strips or glue
- Clean workspace with good lighting
Step-by-Step Process
Step 1:
Remove the four bolts from the engine cover using a 10 mm socket wrench.
Additionally, you can use the wrench to loosen the bolts and then swap for your hands or a spinner handle to completely unscrew them.
Step 2:
Lift the cap off and set it to the side.
You will see four ignition coils. For this tutorial, we will only replace one of the sockets.
Step 3:
Remove the ignition coil connector by pushing down on the end of the clip and unplugging it.
Unscrew the bolt on the other end of the socket plug using the 10 mm socket wrench.
Step 4:
Remove the ignition coil to reveal the spark plug cavity.
Step 5:
Remove the adapter and 10mm socket from the socket wrench and replace it with the 6" extension adapter and spark plug socket
Step 6:
Too much force can cause your spark plug to crack. Unscrew it carefully to ensure no debris falls into the hole.
Insert a 6" extension adapter and spark plug socket wrench into the cavity where your spark plug is located. Make sure it reaches and securely grabs onto the spark plug.
Remove the spark plug by pulling the socket wrench towards you, and loosen it until it unscrews completely.
To be safer, start by using the wrench to loosen it, then remove the wrench handle and unscrew it the rest of the way with your hands.
Lift the wrench and the spark plug out of the cavity.
Step 7:
After you remove the old spark plug, take out your new spark plug and remove its plastic protector.
Step 8:
Once you remove the white protector, take out the spark plug boot protector and open it to spread its lubricant across the screw area of the new spark plug.
Anti-Seize Lubricant is used to allow for easy spark plug removal in the future.
Step 9:
Make sure you tighten enough to minimize the risk of the spark plug being removed from the engine.
Fit your new spark plug into the socket, and insert it into the cavity.
Tighten the spark plug by pushing the wrench away from you, doing so until it's completely screwed in.
To avoid damaging the spark plug while tightening it, start by screwing in the plug with your hands, then add the wrench handle and tighten until it's secure.
Step 10:
Insert the ignition coil back into the cavity, plug in the connector, and screw in the bolt to secure it.
If your ignition coil connector's tab broke like this one did, you can use zip-ties to secure it or replace it. (Part #: 90980-11885)
Step 11:
If more than one spark plug is damaged, repeat steps 5-11 for the rest of them.
