From stop to start in forward and reverse, if I put it in neutral and manually move the car forward or reverse. Whichever method I use as soon as I apply the brakes there is a tink tink sound that occurs. Same tink tink that happens when I go from a full stop to acceleration again. I've noticed this development soon after I got my chip and It's more than likely because I have been accelerating harder since. Anyways trying to determine what component failure is causing this sound I am able to replicate this in the garage only moving the car a few feet either way with the car off and pushing it forward and backward. Once I get the car moving I hop in and jam the brakes...tink..tink. If I move the car in the same direction I just finished braking from no noise. However, If I move the car in the opposite direction of the direction I just braked from and then jam the brakes again...tink tink. I can also get the car moving forward jam the brakes, put it in park walk to the front of the car push the car backwards and instantly tink or tink tink It sounds about like when your loosening a rusted bolt and it is just breaking free or like someone is slapping a pencil on the exhaust. I do know that its not my upper or lower ball joints and I'd have to say the sound originates from the front center of the vehicle. I've worked on cars for my whole life so I've checked everything I can think of transmission,brakes, ball joints, struts, cv axles etc. Anyone else have any similar stress related issues? Anyone?

 

Also wanted to say that I'm not being **** here. It's noticeable and I'm ready to take a sledgehammer to this pos until it quits making the noise. Tranny mounts? Motor mounts? Sub-frame shifting? ANYBODY?

 

Things I'd check are suspension bushings where the control arms meet the frame, missing/broken clips on brake pads, missing/broken bolts on the calipers, even exhaust hangers. Good luck.

 

Dont really understood what u meant ))
could that be your brakes?

 

It's not brakes. It's directly related to the force of braking and acceleration though. I think it has something to do with the subframe. What bushings would be directly affected by the changes in inertia that stopping and starting have on the car? One way I can replicate the sound is to put cvt tranny in neutral turn engine off and push the car forward a few feet, jam on the brakes and the inertia of the car causes the tink-tink sound. Now whatever just caused the tink-tink sound is loaded. Ok, I now place cvt tranny in park, engine still off. I can take however long I want and go to the front bumper and push car backwards an inch or two does it, and then tink-tink. Whatever shifted when I brake hard the tension was just relieved when I push back on the car. I'm sorry for this thread it probably seems stupid for me to be asking for advice on this but I can't for the life of me pin this down.

 

Let me save you some time - it's the INNER brake pad. I'm positive.

There are 3 prongs on the back of your inner front pad that fit into the cylinder. When they aren't pushing out against the cylinder wall enough the pad rattles. When you use the brakes the forward motion pushes it as far forward as it goes and you hear the noise because the top and bottom contact the space they should already be resting in. When you let off the brakes it slides back again to repeat.

I guarantee this is it. To test, go out to your car when the brakes aren't hot and reach behind the rotor. Find the pad and push it forward and you'll hear it.

The brakes work fine and it's safe. If you want it fixed, just remove the pad and spread the prongs out more.

 

Damn! I got excited thinking she'd be an easy fix. Checked the pads. There's no slop at all. I did try something else though. I started car pulled e-brake and set. I can then put car in drive give it a quick pop on the throttle and tink-tink put car in reverse a little pop of the throttle and tink tink. So I guess that means that the engine and tranny shifting while the e-brake is applied replicates the sound as well. It must be one of the mounts but which one is going to be affected by both the engine and tranny under load as well as the brakes being applied. I was under the beleif that the tranny and engine would not be shifting if the tranny is in neutral, so how then would braking cause the stress on an engine or tranny mount?

 

sounds like brakes. a buddy of mine has a tls and his made a noise like that and i told him it was the brakes and he said no its not its not. 2 weeks later he had to replace his rotars pads calipers cost him like 7 or 8 hundred dollars. keep in mind he has brembo alla round since his is typeS

 

sounds like the problem i had with my car, which ended up being the subframe weld

 

You're a year late bud...
