Brake squeal gone- but the click is on- ideas?
Hey All;
Took a chance and bought ebay brakes.
Big mistake, and a few months after I put them in they started squealing like crazy! This weekend I put in some Akebono Ultra Premium pads and they are beautiful- super quiet and stop excellent.
BUT
Was surprised when I heard a click sound coming from the front, under the car, maybe the sound is the brakes, maybe not. I uninstalled the brake pad last night (PITA!), re-lubed metal parts and shims, and retorqued brake caliper bolts and added blue thread locker. Everything seems fine.
When I drove to work in miserable DC stop and go traffic the brakes felt perfect.
But when I go to park, I feel the ping.The click, ping, metallic sound feel is only when I slowly pull into a parking spot at a slight 1 or 2-degree decline.
I know this is a long shot, but anyone else have a similar experience??
Things I plan to check:
1. Dust shield hitting something
2. Brake wear sensor getting stuck
Since it could also be the suspension, will check:
1. Torque on sway bar end links
2. Top 13mm bolts on strut mounts
3. The locking nut on the steering knuckle
4. Tie rods
I also had an alignment recently and changed out front airmatic struts!
Any thoughts???

Try moving slowly in reverse apply brake, then move slowly forward apply brake, if click is heard probably pads slightly undersized in the calliper
Could also check the two bolts that hold calliper carrier onto hub are real tight.

The shim didn't seem to fit super snug on the pad, but I have never had an issue before...
I did tighten the caliper bolts, but I couldn't find the exact torque specs. I have seen torque specs ranging from 30 to 80 ft lbs. I started with 40 ft lbs with my digital torque wrench and then tightened as much as I could by hand.
Thoughts?

It is true when I go slightly in forward and then slightly backward I hear the sound. It is pretty much the only time I hear the sound.
I researched the Akebono EUR847 pads, and I cannot find anyone that has had a problem with fitment.
I'm going to Merchants Tire today to get an alignment, and I will ask them to do a brake check. They are usually bozos though, and may or may not be able to diagnose...

I would definitely say that them pads are undersized or if there's a shim that wraps round them check that, it's the pad contact area in the pad holder, as you brake forward the pad moves down and clicks, as you reverse the pad moves up and clicks. Easily checked by moving pad up and down by hand, it doesn't take much to be under size for the noise to appear. Putting old pads back in would prove it only if you still have them.

PADS TOO SMALL
I would definitely say that them pads are undersized or if there's a shim that wraps round them check that, it's the pad contact area in the pad holder, as you brake forward the pad moves down and clicks, as you reverse the pad moves up and clicks. Easily checked by moving pad up and down by hand, it doesn't take much to be under size for the noise to appear. Putting old pads back in would prove it only if you still have them.
Looking more closely, the retaining hardware was not holding the top of the pad firmly because the pad was a couple millimeters too small. I tried a second set of hardware I purchased, and the pads still did not fit.
When I put the old pads back in (brake motive brand off eBay), and the brakes were perfect. Moving the rotor and wheel back and forth produced no sound.
I went for a test drive and didn't get any clicking, but this morning I did hear something, which I assume is a separate issue, but nonetheless, my brakes sound A LOT better.
I'm going to my OEM brakes, which should get my brakes as good as they are going to get, and I'm very disappointed with Akebono.

rear pads dont fit too

I rushed home from work and got my car on my lift. The front pads were stable and not clicking, but when I checked the rear, they made all kinds of sounds. I'll have to switch the rear pads and wait for OEM pads to come in the mail.
What a PITA. Akebono, you suck!
