Rotor ring mark again! WTF

[Supermang]

Several months ago (less than 4k miles) I replaced the front hubs, all four rotors and pads, one because it was time and two because there was a ring around the rotor. I had read that it is a sign of a warn our hub assembly.

After replacing the rotors and such I noticed that all of my brakes work well except the driver side front does not appear to make much of any contact at all. In fact hardly any signs of wear.

Now the ring is back on the rotor, I do not understand why, I am thinking maybe collapsed brake line or seized caliper.

Can someone please shed some light on this topic or point me to another link. I already have a brake line for it now.

Probably a seized caliper. Pull caliper off and see if it'll collapse with a C-clamp. I'm betting it's not gonna collapse.

[Supermang]

If it does not collapse couldn't that mean that the line collapsed though too, because fluid can't go back through either way?

Doubt a collapsed line would keep it from retracting. I just had one stick on me a few weeks ago and the smell up close was a dead giveaway. My old caliper had been so hot the piston actually broke as I was prying it off the rotor.

[Supermang]

Wow! Okay I will take a look at that, I guess im lucky it didn't seize when braking and lock up the rotor.

[Supermang]

Is it okay to buy a remanufactured caliper?

That's what I put on. Works like a charm

Great I appreciate it! Thank you!
