Pardon my dumbness! Axially meaning in and out in other words touching the caliper


Hmm


Ok I already have them siliconed sideways, I'm going to try ON the discpad and see, maybe it's hitting g the caliper


THANKS

 

No, I probably shouldn't have used than term as it is somewhat confusing; maybe I should have said " axially rotating", as in around the axle. Basically, there are slots on the caliper that the pads clip into which hold them in place as the rotor slips between them. While braking, the torque applied to them by the rotor makes them want to rotate along with the rotor, but the grooves stop that movement, holding them from spinning out. Normally, there is a stainless steel shim piece snapped over those grooves on the caliper that the pads rest on. They are called pad retainer clips. Those pieces can wear down, allowing some extra movement from the pads, or worse yet, sometimes they are removed altogether by a lazy installer. The new pads will still fit on, but really poorly, and would almost certainly clunk a bit as the pads shifted every time they were applied.

Take good look at your brakes and be sure those pad retainer clips are installed and in good shape. Here's a pic I found of some aftermarket replacements on ebay: http://www.ebay.com/itm/RAYBESTOS-H1...471#vi-content
(They are the shiny SS pieces)

 

Yeah I have those clips, even took them out to see if they were the noise, put them back in, new pads as well I had to force over the caliper with the new pads, so I'm really iffy about that being it


But back to the play, the Centre piece (I'm still getting used to the fact there are no axles up front) it shouldn't move around if it's not flush in the rotor with the wheel bolted on I agree, but I just can't help thinking, hoping it's it as the other side the rotor is tight on it!

I'm hoping it's not wheel bearings, and I'm wondering if my ears are fooling me an it's rear axle click.... Arrrrrgggghhhhhhhh

 

Sorry misunderstanding! Those aren't the ones I took out! I tool out the ones that rest ON the pad itself

Those side clips now, are the ORIGINAL diagnosis! I siliconed them to hell and I'm pretty sure the pad cannot still be jumping around in them! (the mech did say they might be worn out OR It's non genuine disc pads with smaller sides that don't fit however I CANNOT get them in my country so I tried the silicone... I'll double triple check them again tomorrow, I HAVE TO SOLVE THIS NOW!!!!

 

The rotor will often stick to the hubs, even when the wheel is removed, rust and corrosion can cause this, but a quick couple bumps with a rubber hammer and they should loosen right up. If you have one that's loose when the wheel is off, and one that is still tight when the wheel is off, it doesn't necessarily mean anything because, again, once the lugnuts are tight, there is should be no free play on either of them.

Yeah, I think I may have to agree with your mechanic. If you can't get those retainer clips, it does make me wonder about what sources you have for the pads themselves; are they fitting as perfectly as an OEM pad would? I know lots of aftermarket pads are used all the time without any issues, but since you mentioned being in another country where you can't even get the clips, it is quite possible that your pads are not to spec, and that would be the most logical explanation for the free play which allows the pads to shift, and causes the click.

Additionally, I can understand the idea of trying silicone, but it is a bad idea. The pads need to move about freely. They should be lubed with high-temp brake grease, not stuck/glued to the retainers. I doubt that the silicone is even firm enough to prevent the shifting of the pads though. Under the kind of forces seen by the brake pads, the silicone should quickly be pinched out of the way by the hard metal surfaces to either side of it. I think all that silicone will do is gum up the works when the pads need to shift sideways as they wear.

 

To be honest I'm really not sure if the pads I got on the car were genuine, they don't seem to be different, the genuine ones are hella expensive

 

Well in my case I am still running OEM, actually the noise started without doing anything to the brakes..... When I got the car they (infiniti dealer) put new rotors/pads on all wheels.... No noise until a couple of months ago, about 25.000kms.....

 

It's hard to imagine a dealer not installing new pad retainers, but maybe it's worth a quick check just to see that they are indeed there, and that they are in good shape.

It is possible to set the car up on stands*** at all four corners (since you have an X model) and then have someone get in an carefully put the car in gear to engage the drivetrain back and forth in forward and reverse, with the application of the brakes to stop the drivetrain between the forward and reversing, and all the while you listen carefully from right alongside the wheels. This virtually eliminates the suspension from any contribution to the problem and you can see as well as hear exactly what's going on with the brakes as well as the drivetrain.

*** BEWARE - - - THIS IS POTENTIALLY DANGEROUS! You should not attempt this unless you know how to do it safely. If you do not know how, then you should not do it.

 

Well I tried that but mine isn't an X so I jacked up the front wheels only


I Damn near killed everyone in the apt!!!!


'lol, I kid I kid

Really and truly, I'm fed up and don't care to find out what the noise us, f**k it, lol

 

It should be even easier for you.

With a RWD car you don't need to lift the rear because you don't need the drivetrain to spin the wheels; you can just spin them by hand. Just get some gloves on and grab the tires and spin them around, over and over to get them up to speed, then have someone inside tap the brakes while you're right there to see if it clicks.

 

I've done that! But didn't have anyone to press the brake, lol and no jack stands so I wouldn't risk it, but I have actually heard the noise by changing direction without pressing the brake


I looked at some control arm kits I might buy from energy suspension

 

Ok I'm just testing it a bit and it IS XEFINATELY in the suspension, after I press the brake the suspension Rides then you hear the click, it's the control arm bushings I know it is! I just gotta spend the cheese.. About 170us landed I get the whole kit, red or black, obviously I'll order red!

 

I BELIEVE I HAVE FOUND IT!!!!

NOISE GETTING WORSE so I decide to go under the car and grease everything going a d feel around...


The TIE ROD END at the end of the RACK END when I rotate it I hear a metal to metal noise! Should never be the case, I might sell the car this week (with info to new buyer of course) if not I'll get some rack ends a d tie rod ends this month end! (I actually knew they needed to change but didn't know it got that bad)

Thanks for all the help guys

 

Maybe the compression rods have been the annoying noise?

People typically replace the rubber piece to make the noise go away.

 

Hey Jomo Bailey.... did you find the problem? I triple checked all the suspension componets on the front end and could not find anything lose, the busghins seem to be ok. I had the car on a lift so I was able to look in detail......nothing. HELP PLZ!!!
