My 2000 grand cherokee makes this clicking noise on the driver side rear brake.
It happens at the beggining of the the braking, once I press hard it goes away. I took it to the dealership, they said it was dry slide pins...they lubed them up (charged me $150...buggers!), the sound went away and it came back 3 days later.
I've replaced the rotor and the caliper but the sound keeps coming back...I greased up the pins again (myself this time) and the clicking goes away for a few days and then returns.
Anyone have any idea what is causing this (warped axle, hub bearings, ???)? I'm tired of dumping good money after bad on the piece of crap car of mine!
Im not sure of the setup on your jeep but do the pads set on thin metal clips? If so there is a good chance that the noise you hear is the pad jumping cause the clips are wore and need replaced, although for the year of it that would be strange but is a good possibility. Are they factory pads?
The pads have been replaced TWICE...and they're the chrysler pads. One pad clicks into the piston side of the caliper and the other floats...It seams like every mechanic we've taken it to takes a guess and has us replace yet another part...so far we've replaced the pads, caliper, and rotors...what's left?????
When I grease the caliper pins, the probem goes away and then 3 days later it's back! I'm going nuts!!
When you grease the caliper pens you are pulling the pads, have you used the glue on the back of the pads to keep them in place? Are you allowing it to properly set before use? it sounds like the pad is moving when you apply the brake.
Also, you need to check the e - brake unde the rotors. Are they ok?
If you grease the slide pins and the noise goes away, then you know the area where your problem is. Either the mounting bolts that go thru the sliders, the sliders, or both are worn. When you replaced the calipers, I assume they come with new mounting bolts & sliders?

Any parts store will know. Usually always right next the the caliper lube. It is called Disk Brake Quite. VERY cheep and important. It keeps the pads from riding on the rotor when not using the brakes. It is a glue.
The trick is to apply to the back of the pad when putting back together. My "technique" is to put the glue onto the back of the pad only where the caliper toughes the pad. Press the caliper open JUST far enough to slip the pads over the rotor so the caliper holds the pads in place snugly. You don't want to have the glue in there and dry with space between the pad and caliper.
I have also after reassembly before tires, pressed the brake peddel to clamp the pad and caliper to hold in place. Then LEAVE it to dry.
THIS IS KEY, YOU MUST LET IT TOTALY DRY BEFORE DRIVING OTHERWISE YOU MESS UP THE HOLD.
Also, be very careful to NOT get any on the rotors or the face of of the pad. This is very bad also.
Your hub bearings could be dried up - sometimes it clicks or squeals when they dry up - and unfortunately it is one unit (the hub) and cannot be opened to manually lube the bearings - meaning you have to buy a whole new hub....just a thought - something to look into...its hard to diagnose with this because it only happens when you are driving, and you can olny hear it when you are slowing down usually....

I tried the Disk Brake Quiet glue but no luck. When I grease the pins, it works a few hours and starts again.
It makes the "click" sound once in each tire rotation at the same spot in the rotation. It sounds like to pieces of metal hiting eachother at slow speeds, and like a chirping sound at higher speeds. I only hear it when I press the brakes. When I let go, it goes away.
Could the "clicking" be loose bearings? I"m running out of ideas. I'm wondering if it's something else behind the rotor, like the parking brake.
Here's what I've done so far:
Disk Brake Quiet
Greasing the Pins
Also tried 3 Mechanics (including the dealer)
The caliper pins are new also...they came with the new caliper I put on last month.
Yesterday I pulled off the roter, cleaned the ebrake pads...they had a ton of grease on them...I also loosened them a bit. My thinking was that perhaps they were getting pushed around by the rotor when braking...no luck though. Maybe I'll try tightening them instead? Who knows...I'm grasping at straws here.
by the way, somebody said it might be a bearing problem. Is there a way to tell? I've heard replacing them is expensive and there's no way I'm putting more money into this piece of crap.
