How To Diagnose and Replace a Faulty Caliper

[EricTheCarGuy]

I feel this is a fairly straightforward video but I welcome your comments.

As I understand it, you need to lube the caliper pins with silicone paste and use copper grease (I think that’s what Eric called antiseize) on the area between the back of the pads and the shims (though Eric didn’t do this), and the tops and bottoms of the pads where they fit into the caliper. Can I use Permatex dielectric tune up grease (silicone based) for all of this? I have a tube of it.
Thanks

I recommend things just the way I show in the video.

I cant move my calipers piston enough to fit the new rotor and break pads, I just need ~1mm… I am trying to do that while it is connected to the system, would it be easier to push it if it would be disconnected?

You might try cracking the bleeder valve open. However, you might just have a caliper that’s about to go bad. If it doesn’t move easily with the bleeder cracked open, I’d say you probably have a bad caliper.
