Hallo zusammen

Habe nun etwas mehr als 13'000km auf meiner C7 Stingray.

Nun pfeifen/quietschen die Bremsen, aber nur bei Schritttempo d.H. wenn ich nur sanft bremse.
Die Leute verziehen das Gesicht vor Schmerzen wie lästig das quietschen ist.

Wie und was kann ich dagegen unternehmen?


Gruss
David

Moin zusammen!

Habe jetzt 30.000 km mit meiner C 7 auf der Uhr und genau die gleichen Probleme.
Werkstatt kann nichts erkennen und sagt "alles in Ordnung"

Wir sind nicht die einzigen, in the USA ist das Problem auch verbreitet, hier die Lösung von GM:

I recently complained to my service center about my brakes squealing at low speed braking... like in traffic... and they sent me this bulletin. Basically the solution is to apply a lubricant to the brake pad and it looks like it applies to more than just the '14 vette.

I'm skeptical that this will repair the problem but I'm willing to give it a try. Has anyone had this done on their vehicle? Did it repair the issue?

Im still going to try it but if it doesn't work I think the only thing to do is to swap out the current pads with ceramic pads.

This PI has been revised to update the Models and the Parts Information. Please discard PI0917A.

Condition/Concern
Some customers may comment on a squeal or squeak noise from the front brakes. This condition normally only occurs on initial brake applications after the vehicle has sat for an extended time. The condition occurs typically under light braking, in speeds under 16 km/h (10 mph). After 1-6 brake applies, or after braking at higher speeds, the noise no longer occurs. This condition may occur more often in high humidity conditions.

Recommendation/Instructions
Important: Do not apply the lubricant to the back of the backing plate.

Apply a light coat of the lubricant to completely cover the pad backing plate abutments on each end. The lubricant should not extend onto the friction material. Refer to the illustration below.
