Sticking caliper or bad caliper rods?
This week brought on a weird grinding noise on the pass side front wheel and it is definitely not the tire as it sounds very metallic in nature; at first I thought wheel bearing but when the brake pedal began to act weird I thought stuck caliper piston.
This evening I was able to jack the car up and spin the wheel but it barely wants to move.
I did a google and apparently the older LS had a problem with the rods rusting or whatever up; I wouldn't know for sure until tomorrow and wanted to take it somewhere by then because it can only get worse!
Anyone else ever have this issue? Imagine the sound of stopping a car that has no pad left; kinda that woosh woosh woosh grindy sound but my car does it when the brakes aren't engaged and you are cruising/accelerating. Yikes.

Ended up taking the rim off and the pads are getting close to the sensor so that'll need doing soon; had the rotors resurfaced but if I do the brakes I'll get all new stuff. Tired of rusty, non OEM crap!
From what I can tell, the pins look okay but that inside, upper piston looks different than the rest. No residual fluid but when I took the slotted screwdriver to it there was dust gumming up on the metal (not a lot) but enough to think its time has come. Guess I'll make some calls tomorrow.

Don't know what year your car is, but take a look at the back side of the rotor too. I've seen a few LS's where the ball joints/ wheel bearings go out and the rotor rubs on the ball joint. I'm not saying this is your problem but take a look to make sure.

My '96 has a weird intermittent metallic "banging" sound that happens with no pattern except that it is always at over 70 mph, my brakes look and work fine, I am hoping someone else has this and stumbles on to the solution!
