What front disc are these?

[71valiant]

I'm in the process of bleeding brakes....kinda curious what this setup is. It's on a 67 Valiant.

And shouldn't my inner pad click into the caliper piston? Because it doesn't. It's just floating there.....

Those are the "Slider" type single piston caliper.
Most likely 73-76 A Body disc brakes.
But without me looking at a picture of your actual spindle (knuckle) they might even be off an Aspen, Volare, or other body style car.

No, brake pads don't "clip" into the caliper piston on a brake system such as what you have.

Ok. Thanks. I was assuming they were a stock style. I've got a 73+ k member. So that's what I figured. The no clipping in the piston threw me. Lol

Those pads sometimes need "adjusted." Read the 73 shop manual which you can download free at MyMopar.
