Stinger gt break issues

[Ryanzzz]

Hi,

I have been have issues with my breaks as they have been squeaking pretty bad. The pads are fine and everything is fairly new. I have 12k miles. Has anyone else had this problem and know a solution?

What pads are you running?

I havnt even looked. I got The car a month ago. I’m assuming what ever comes stock.

Stock pads "usually" don't squeal is why I ask. The OEM pads will most often cause shaking. If the PO fitted aftermarket pads that could explain it, some of the ceramic pads will squeal.

Okay thank you, I’m gona take them off and see what I’m working with.

Even the owners manual alerts you to the fact that "high performance Brembo brakes" will commonly make 'rrrr" or "scratching" sounds and this is "normal operation". That's probably for the benefit of the non US owners, who get European spec pads that actually stop the car like a performance car should, and are not quiet. Also, they put out more dust, which apparently US drivers will not put up with: we want quiet, clean brakes: and because that dominant demand means a different pad compound, some of us get the "shudder" instead. When you swap out the US OEM pads for aftermarket, as mentioned (and experienced by you), anticipate the possibility of dust and noise in place of the "shudder" from pad deposits on the rotors.

Is it possible that a good cleaning will help?

Yes, possibly. And maybe some light grease on the back sides of the pads. Mine (stoptech) were squealing something fairly fierce after about 2+/- years, but it was intermittent even from the same 40mph-50mph stops. I only cleaned my fronts, used brake cleaner (for the calipers and hardware). There was some serious gunk in there (expected), so I felt it was worth it. I then bought some brake grease and put a light coat on the backs of the pads and some on the hardware, and NOTHING on the friction surfaces of course. They're not quiet as a mouse, but MUCH better. I'll probably do the backs this weekend just for completeness. If you got the jack stands and are comfortable taking off a few wheels...pretty easy job.

Perfect. I’m gona do that today. Thanks for the help!

My guess is the previous owner installed semi-metallic aftermarket pads. Ceramic pads usually dont squeal as mentioned above, typically ceramic pads are the least likely to squeal. The reason the prior owner probably did this is because the Stinger oem pads are notorious for causing brake vibration and many owner go aftermarket to avoid it.

You might be able to get it to quiet down a couple ways. You could remove the pads, clean them up and regrease the pins, back of the pads and the edges where they contact the caliper. You could also attempt to re-bed the pads and that might help. But its totallly possible none of that will solve the issue especially if the prior owner installed an aggressive pad, if they did that then some squealing is totally normal.

Its only happening braking right?

Yes it happens when

yes, it happens when I’m braking at low speeds. Like when parking or pulling out of my driveway.

I've read a lot of posts about shuddering and noisy brakes. I've seen none of this. Car is a 2022 GT1.

Not challenging anyone, just saying it isn't happening on my car. Don

Welcome to the club. I've tried Gloc GS1 (street pad), had a couple of race pads, DBA SP500 (or XP500?), etc. They all do it at low speeds. I'm almost ready to go back to stock (just yesterday put stock rotors / pads back on the rear, still trying to figure out what to do about the front).

What type of "brake grease" have people been using? And how to clean calipers? Just spray brake cleaner on the whole thing? That won't affect the rubber bits?

I used CRC Brakleen...I can't remember the "style". I wanna say it was this one... https://www.autozone.com/brake-and-...lorinated-brake-parts-cleaner-14oz/219615_0_0 I pretty much sprayed it on all the brake parts, not the rotors though. There was a lot of gunk, so I think it helped.

For the brake grease I used this (the amount was way more than I needed, but it's what I saw first)... https://www.autozone.com/greases-an...synthetic-brake-caliper-grease-8oz/826455_0_0

Seemed to work for me, not perfect...but much better.

When I removed my stock Brembo pads they had 2 shims (one attached to the pad) and some kind of double sided sticky tape on the inner edge of the pad. They didn't have any grease applied.

I tried to replicate this with my Bosch pads by adapting the loose shim and some tape in the same location. So far no noise at all.

Here is a good picture, the blue is a sticky pad.
