HELP!!! Best test for stuck caliper?

[we350z]

Well OK i completed the flush. Took longer to jack the car up on all fours almost than it took to flush. This power bleeder really is handy dandy, works like a charm. The shit that came out is definately tea/cola colored. It is some nasty stuff for sure. I was careful not to get it on the car but i did knock my catch bottle over. Good thing I have epoxy floor paint covering. I am too tired and lazy to put the wheels back on and put it on the ground to take it for a test drive tonight. Though I did push the brake pedal in a couple times and it feels really firm. More so than it was before. We'll see - I hope this did the trick. Let you all know tomorrow.

Bump..

Fix your issue?

Well I took it out today and test drove it a little. It doesn't seem as bad now but I still think there is some shudder. Actually seems like it goes to the left now.... WTF? Some of the roads i tested on weren't quite perfectly flat. So I want to try this on a stretch of nice even flat road. I also am contempating re-doing the bedding procedure.

I am puzzled. Maybe it just isn't broke in yet. There is no explanation for this that i see. I think I will test drive it again after i do the CV boot and if it's still messed up I will let the indy mechanic deal with it.

ne1?

OK I did another road test, did a bunch of laps in the church parking lot next store and on a newly paved stretch of straight road. Shudder is definately still present. I don't think it's as bad as before but hard to say.

I did the finger touch test. All 4 rotors were hot, especially the fronts. The driver side and passenger side both felt like they would burn my finger had i left it there longer than a split second. I tried to get scientific with my radio shack digital indoor/outdoor temperature guage. I hovered the probe inbetween each side of the rotors. Both sides hit 157 degress than the reading went to HH.H since It was too hot for the thing to read.

That being said. I guess I have a suspension problem. Go figure. Oh well brakes needed bleeding anyway and was good learning experience for me. I am debating on whether or not I am going to do the pass cv boot or not since its a pain in the ass. I might just let the indy handle it and ask them to take a look at the suspension while they are at it.

So I just came back from the dealer today and had a brake flush and my CV swapped due to a ripped boot.
And to my suprise my shudder is gone.

So I'm not quite sure if it was something related to the CV or the brake flush.
I'm leaning towards the brake flush.

Fluid doesn't shudder. Rotating components do.

Bet on the CV, not the brake fluid flush.

i still seems to be doing this very slightly, and also now i have notices a steering wheel vibration on the highway. Another thing is a thud sound on the driver side when i enter driveways and stuff. I took it back to the shop they are shaking it down.

Bushings are still dead on center. We'll see they thing it could be one of the ball joints or tie rod or something...

did you get the whole axle replaced or just replace the cv boot?? if it's just the boot, I don't think the new brake fluid and the cv boot would fix the shudder. I guess maybe some suspension components were out of torque spec and getting loose a bit. in the process of putting things back on, your mechanic torque everything to spec. so, the problem is fixed.

Well when they installed the bushings recently everything should have been torqued properly by them. So my guess is I have some other bad suspension component. I should know shortly.
