Default Stuck Brake Pads

My neighbor has a C7 (14) and tried to change his front brake pads. He said the pads were not loose after pushing them back off the rotor. Wont come out. Same issue on both sides. Tried tapping with a mallet, no joy. Wonder if anyone else ever had such a dilemma... Ive watched the video and can see no reason for them to stick unless at some time they were tremendously over heated ??? Doubtful though, he is a "mature" driver and treats his car like a temple.

Try pushing the pads outwards to help relieve the pressure off of the pistons after removing the pins and center bolt, they should slide out, I just done mine today on my '17 GS

I had the same issue. The stock pads have a soft, rubber shim on the back side (used to reduce noise) and this causes them to stick to the caliper pistons. You'll need something like a putty knife to carefully pry them away. Just be careful not to cut into the dust boots while doing it. You can also use the "ears" where the pins slide thru as a leverage point with a screwdriver to help encourage them to pop free. Make sure the pistons are retracted as much as possible to allow room to wiggle the pads back and forth.

Go to 6:40 and watch the master @Ozzstar work his magic. You will not be disappointed!

One item that I have pause on that video. It flashes up to use thread lock on the nut with 20lb ft of torque. Using thread locker will lubricate the threads and screw up the torque reading. You will actually over torque the nut on the caliper. Putting it back together will work just fine if you don't use thread lock on that part of the process. Other than that, good video.

yep, that's what I did. I skipped the thread lock. Not needed.

Early 2014's had very strong 2 sided tape on the back of the pads. There's a good discussion of this in the forum. I believe JerryU modified a putty knife to break them loose. He did a whole writeup. Not sure if this link but give it a try. Go to page 9 of the PDF.

If you will note when taking out the bolt, there is residue of thread lock on the threads from the factory. Use blue locktite..20 lbs ft. is minor torque. It's what I did. Do what you want.
