TSB for 2012 rear brake squeal

[ComfortableLiar]

I know I saw a thread on this topic before but I can't recall if it was on here or another forum so he we go...

About two weeks ago my car developed a squeal coming from the brakes under light braking at slow speeds when the car is cold. Sounds like a wear indicator rubbing on the rotor which is impossible seeing as how my car only has 4,000 miles on the clock. So I get an appointment for 2pm today and drop the car off. 2 hours later I get a call from the service manager saying what I expected them to say "we can't replicate the sound". I know I saw a thread for a TSB on '12 Mustangs with certain build months that covered a squeal coming from the rear brakes caused by some type of anti vibration tab on the rear brake assembly. So I bring that up and they tell me there's no such TSB showing for my VIN#.

So I take the tech for a drive in the car with yours truly in the driver's seat. Lo and behold I replicate the sound NUMEROUS times under light braking at slow speeds. The tech is sticking his head out the window each time listening for it and yet he says HE STILL CAN'T HEAR IT. Needless to say I'm pissed cause I know I'm not hearing things. Once the car warms up the sound basically goes away, so the car is staying at the dealership overnight till a new tech can drive the car in the morning when it's cold. Anyone have any experience with this issue or a link to the thread I'm talking about? I did a search but didn't come up with anything on the topic. I apologize in advance if I'm rehashing an old topic. Sorry but I just had to vent to you fellow enthusiasts. It really gets me when dealerships always use that whole "we can't replicate the sound" line.

UGH.

Mine has a chirping sound and I took it in twice for it. The first time they temporarily fixed it and the second time they told me they couldnt replicate the sound.

Brembo cars? Clean the wheels well. Pressue washer. The dush really causes an issue. If i go a long time with out a wash i get squeal till i clean the wells and spray the calipers out.

What about non brembo cars like mine?

Google the tsb and give them the number its for the anti rattle clips or just pay the $25 for the parts and do them your self in under 30 min (i said screw the warranty and slapped a tvs on)

12-1-1 BRAKE SQUEAK/SQUEAL - REAR BRAKES - BUILT 7/19/2011 THROUGH 12/1/2011

Publication Date: January 5, 2012

FORD: 2012 Mustang


ISSUE:
Some 2012 Mustangs built 7/19/2011 through 12/1/2011 may exhibit a squeak/squeal from the rear brakes during brake application and/or when making turns. The squeak/squeal sounds like a metal-on-metal noise (similar to a brake wear indicator noise). This concern may be due to a rear brake anti-rattle spring clip contacting the brake rotor when applying the brakes due to a broken locating tab on the anti-rattle spring clip. This may allow the anti-rattle spring clip to lightly contact the rotor causing the noise.

ACTION:
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

Remove rear brake pads, refer to Workshop Manual (WSM), Section 204-04.
Care must be used when servicing rear brake components without disconnecting the parking brake cable from the brake caliper lever. Carefully position the caliper aside using a suitable support or damage to the parking brake cable end fittings may occur.
Do not allow the caliper to hang from the brake hose or damage to the hose may occur.
Replace new anti-rattle spring clips from brake hardware kit on both rear calipers even if the clips do not have broken retaining tabs.
Install all hardware supplied with the hardware kit.
Install original brake pads.
Position the brake caliper on the anchor plate.
Install the two (2) brake caliper guide pin bolts until snug.
Tighten the right hand caliper guide pin bolts in the following sequence:
Tighten the top bolt to 33 N-m (24 lb-ft).
Tighten the bottom bolt to 33 N-m (24 lb-ft).
Tighten the left hand caliper guide pin bolts in the following sequence:
Tighten the bottom bolt to 33 N-m (24 lb-ft).
Tighten the top bolt to 33 N-m (24 lb-ft).
Install the wheel and tire, refer to WSM, Section 204-04.

Thank you Swetrid!!!

Double post FTL!!

I have a horrific Chirping under light braking only as well. If i lay into the brakes harder i get nothing. But I also noticed it making the noise when hitting some bumps. I also got the sound to be worse with 1 click of the ebrake and it totally goes away with 3 clicks.

OP try driving a little with the Ebrake at 1 click and see if it makes the noise constantly. And see if it goes away with 3 clicks.

I too was told "we cant hear the sound" from the dealer. Im really curious as to what is making my noise, obviously Im leaning toward the ebrake now...maybe this will help you diagnose....keep us posted.

 

[mustang_guy]

I bought the hardware kit for $20 and did it myself.
Didn't bother with the dealership

Where do I find this TSB at?!?!?!

 

[BADBOSS]

Just ordered them myself and going to fix it. Took to the clowns at Jones Worst Ford in Reno and they couldn't hear it either.
