tocking when i stop, What the heck? Options

[D-Man]

okay, so i just changed my rotors...

I did the pads as well, everything was done correctly. I live by the law of doing it once, and doing it right. However, with the new rotors, on the front driver side, there is a tocking noise when i stop (tick-TOCK) tock noise. I can feel it in my break pedal as well, and i had another member (an ace of trades) over this night to help me trouble shoot the problem...

At first i thought it to be a loose clip (between the caliper and the pad) but i have readjusted it 3 times, and with my buddy over we did it again. This time we bent the flex of the clip to ensure proper connectivity. However it still tocked...

It is a noise that you can not only hear, but feel as well in the pedal. It's driving me nuts. This was not an issue on the old rotors. Plus, i know for a fact that the rotors are not warped, it only does this on breaking.

could i get any ideas? help? something? WTF? theese are nice rotors and i dont wanna revert back due to this...

there should be 4 bolts in there, 2 17mm bolts that hold the cage thinger fast. then 2 14mm bolts that hold the caliper to the cage. when you start the 14mm bolts, they go through the caliper and theres a little nut in there somewhere, you need to hold that and tighten, otherwise it may just tighten itself into the caliper and not move correctly, or it will back out and become loose giving your caliper some play, so when you tap the brakes it allows the caliper to move. since you have slotted rotors, if the bad is at an angle aganst them instead of sitting flush, one of the corners may be making the tick tock noise as it falls into then pushes out of the rotor.

just a thought =/ but good luck

edit - heres a pic, theres a round piece on the cage, then that nut, hold the nut with an open wrench, then put the bolt on and tighten down (like 30-40lbs)

genius - we saw evidence of this on the corner of the offending pad. Now we're getting somewhere.

D-man to answer your question - i have no idea where we would find the measurement for this however, we can measure mine and start from there.
Or you could just change out those pesky rotors for my perfectly good working ones and problem solved

HAH-HAH!! And then i can just throw those pesky drilled and slotted rotors to the trash can (where you'll be waiting?) no~

But that does give me an idea... the front 2 rotors have a VERY small amount of play before you mount the tire on, I wonder if it's being held tightly, BUT sitting at an angle on the lug bolts? With the tire holding it on, it could very well be holding it at an angle, where just 1-2 bolt threads high; but would force the rotor to hit the caliper, and that would explain the feel of clucking, as well as feeling in the pedal. And would explain the synchronization of the rotation of the wheel and the clucking.

Now we've made some progress. P!SS OFF BREAK CHECK, I got 6gc.net

Lets find out tonight. I'll let you guys know in the morning. (Thanks Jason)
