this is gonna be a weird one. First thing first, car is driving normaly. Braking normally as well, wheels alignment has been done. There are no handbrake pads in rear discs. I bought the car without them. Rear shocks are completely and utterly dead, new ones are ordered.
Today when i started the car something snaped like small firecracker, dunno if that’s important, but the car runs fine, gear changes are as per usual, braking is fine. Now…
when I brake heavily it sounds like somebody is throwing pots and pans under car. I need to be driving at least 40 and brake almost to the point of blocking the wheels. When i accelerate like a maniac, no noise, during slow braking no noise, while driving no noise, only when I push brake pedal as if my life depends on it. It sounds like it’s coming from the rear of the tranny, diff and/or rear brakes area. I cannot figure it out. Anybody had simmilar issues?
Did you remove the rear wheels and look at calipers, strut rod bushings, shock bushings, trailing arm, etc.?
I assume you mean there are no brake shoes inside the rear rotors.

yes, exactly that. I’m not familliar with all the english names for all the parts, sorry.
Anyway I was thinking of jacking up the car, removing the wheels, putting it in drive and trying to simulate heavy braking. I’m just affraid it has something to with tranny or a diff. Everything else I can fix.

The rear suspension was not designed to hang down and put the vehicle in gear.
Can't offer any suggestions beyond what has already been said, but I'm very interested in hearing what you find. I agree that something making that much noise should be fairly obvious upon inspection. I can't help thinking it might have something to do with the missing parking brake hardware. Might still be some parts in there that have started rattling around. I also think the suggestion about the differential pinion mount has merit. They have been known to fail and the 'firecracker' sound may have been the bolt breaking.
took both wheels off. Everything is in order, tight and lubricated. Used the time to fit new brake shoes and complete new hardware. Issue still remains. Although i have a possible culprit just need to go and raise the car to friends garage.
I think there must be some kind of metal shield or even losened handbrake wire which i think by innertion ends up being rubed upon.
it’s something like that.
BTW found something else though
That one’ll wait, all screws are in place. Once I’ll be doing the rear mounts and shocks, I’ll try to fix those too.

Take a close look at the 4 bolts under the differential, and make sure that they are there and tight.
Has the other side of the spring shifted?
All your rubber cushions need to be replaced and as mentioned before look at the front differential cushion.
Yes, the strut rod looks to be bent so look closely at those bushings too.
Yes it’s bent. I’ll have to order that one too. I guess straightening it is not a smart idea. Thanks for the tip, I’ll check the screws. I’m not driving like a maniac and this is only a “go grab some coffe with friends” kind a car.Yes the other side of the spring has shifted too. From the rust marks it seams it has been in that condition for quite some time.
Do you think it’s better to replace the spring or refurbish this one?

Replace the spring. For whatever reason my 2 older ones also slanted.. something must be tweaked as they wear.
new one all straight.
here is a thread i did. You don’t need to do right away unless as above its squirelly https://www.corvetteforum.com/forums...af-spring.html

I don't see an issue with straightening these if you have the ability. The forces exerted on them are longitudinal, not transverse (side) so you aren't weakening them. They get bent from lazy alignment guys who decide to pull the bottom of the wheel inward by taking a BFH to the struts instead of using the cam bolts.

Pots and pans - weird noise
