im no mechanic or anything but
could it be a piston seal and boot need replacing ?

i was just looking at the service manual it says always replace after every disassembly ..

it could be worn out...

you can download the service manual to see for yourself ..

 

no idea im gonna take it back to monroe

 

it could possibly be the wheel bearing.

 

Im not 100% positive if the sedans emergency brake is the same as the coupes but if it is you should check to see if the shoes that are inside the rear rotors are worn down. If they are replace them. If they aren't, maybe all you need to do is adjust their position using a flat head screwdriver and turning the adjuster star at the top of the brake assembly where the wheel/slave cylinder would normally be. I hope that can fix the rear noise. As for the front make sure the backing plate isn't bent and ask the guys at monroe if they used any type of silicone on the pads when they installed them. This prevents the pads from shaking inside the caliper causing a squeeking noise. Btw I am a mechanic but it's still really hard to diagnose a sound without hearing it in person.

This is a basic drum brake diagram. The adjuster in the g35 is on top of the assembly where this diagram shows the slave cylinder.

Yes, the sedan brakes are the same as the coupe brakes, except for the Brembos, of course.

 

i dont have drums i have rotors, calipers, pads

 

The way the emergency brake works is different from the way the driving brakes work. The driving brakes use a caliper and rotor system but the emergency brake uses a drum system. The drums are actually the inside of the rear rotor and if you remove it you will see a shoe assembly underneath. Again this drum brake is only used for the E brake.

 

i think i'm having the same problem coming from right front. Mine is more like something metalic vibrating. I'm changing the pads and rotors today...will see if that gets rid of it. I

 

New rotors and brake pads did not take it away. Have no friggen clue what it is and its driving me insane. It gets so bad when on rough road. Somewhere to the rightside.

 

check and see if the clips that seperate the brake pads from the caliper bracket are seated properly. sounds to me that the clip is hitting the top of your rotor causeing your tapping sound. either that or you got a a brake pad that seperated.

 

Bump

Did you fix your problem yet? I want to know how to fix mines.

 

same problem for me too..

 

Sounds like u guys have a bearing issue a dust shield touching will make a loud high pitch noise. A bearing will be a lower tone and will be felt in the steering wheel. Pads/rotors can cause. Various issues like pulsating pedal a grabiness at low speeds. This can be caused by seized caliper putting excessive side pressure on the rotors causing it to wear unevenly. A worn or torn boot will not make this kind of noise. I just replaced my front pads And rotors and when I reinstalled them it made A racket because the dust shied had gotten bent somehow when I had it off or it was slightly Bent before but due to the old rotors being so worn they did not touch. A Broken or missing pad clip won't do this either. It would cause a clicking or clunking as the wheel rotates. I think one of u said u had this problem. ThAts a missing clip. The pad grabs the rotor slightly and moves with it in the caliper then it let's go and slams and forth in the caliper. Won't cause any major drivability issues just annoying noise. Those clips are there for a reason. That's why they are called anti rattle clips. Hope this helps

 

Sorry for bringing back such an old thread

 

all good! had an issue years ago, and we thought it was break related... turned out to be a rear tire? odd stuff man
