Signs of frozen caliper bolt?

[The G-Man]

I think there is a frozen caliper bolt on my Mom's Odyseey. What happens is during the last few moments of braking before stopping, I can hear this sort of grinding noise comng from the left front brakes.

Ii think there are little metal clips on breaks that might make that noise when they are getting low, but if it is like a real hard grinding noise i would get them checked out.

if it were a frozen bolt or pinthat particular pad set would have uneven wear throughout the entire pad surface more likely to be on the majority of one side whether top or bottom bolt/pin

Plus the rim will be abnormally hot if the caliper was kinda locked up. We had that happen on a merc MLK320? Something like that one of the SUV turns out the piston was rusted in the housing.

yea and i dont think that it have a grinding noise

It is not the chirp of the wear indicators. It sounds like the caliper is not moving right. I replaced the brakes back in June.

It kinda feels like the pad is getting stuck to the rotor.

ya...my accord calipre bolt actually froze too...what happens is like the guy said above, it will wear tremendously on one side at a large angle (like 1/4" different from top of pad to bottom). Then it might even wear to the metal of the pad beacuse it is wearing unevenly and not effectively and getting the bottom much faster.
it would be wise to take the calipre off and either get a new bolt or calipre...ideally before the disk is destroyed by the metal on metal braking.

Also, the grinding noise could just be the signal tab running on the disk

If a caliper slide pin/bolt seizes up you will get premature pad wear and it will wear awkwardly, usually not flat but cocked. Frozen caliper piston usually wears the the pads unevenly inside to out, but still remains flat.
