For that piston just use a c-clamp and a piece of wood to protect it if its being difficult. Works like a charm.
Took the words right out of my mouth.
I recently just replaced the brake pads for the front brakes of my car. Now, I have to do the rear too. From what I heard, its almost, if not the same procedure as the front. Here is a list of the tools & parts that your going to need for this.
- ratchet (14mm)
- hammer or wooden mallet
- rags
- brake pads (obviously)
- Squeak Stop gel (optional)
If I'm right and the steps are the same for the back as they are for the front then this is how you do it.
Step 1 - With your car already jacked and secured up and the wheel removed, you should remove the 2 large bolts that secure the caliper to the axle. They are located behind the rotor, one on the top of the caliper and the other on the bottom. Remember to work in reverse since you are not facing the bolts. This is the hardest part btw because those bolts most likely will be a "B" to remove. If they don't budge, then use your hammer or wooden mallet to loosen up the bolts. This may take a couple of wacks too.
Step 2 - Once you get those bolts removed, carefully pull the caliper away from the rotor. Don't let it hang though. You don't want it to snap any lines off. At this point, simply push out the first pad, the outer one. Leave the pad that is on the side of the piston on for now.
Step 3 - With a c-clamp, push the piston back in using the pad as a buffer until you get resistance. Then proceed to remove the old pad.
Step 4 - Apply the Sqeak Stop gel to the pads as instructed on the instructions (Usually behind the pads or at the points of contact), then insert them in the caliper. Make sure they are in there good and secure.
Step 5 - Now work backwards to complete your job. Make sure you properly torque your bolts and pat yourself on your back for a job well done.
For the rear brakes, you want to skip step 3. Instead as other have indicated below, remove both pads and screw the piston back.
