Brake Release..... Won't Release

69 Camaro

The parking brake release rod is stuck... I believe in the "open" position, eg; I think it is pulled all the way out.

I can depress the parking brake, and I can release it manually with the lever on top of the mechanism. I haven't pulled it out, but I sprayed a bunch of greased lightning all up inside the mechanism but it won't budge. There's a bit of surface rust all over the parking brake mechanism, but it sets and releases (manually) just fine, I think something might be rusted shut, but I'm not sure what to look for. There's not a lot of room to look inside to see how it works unless I pull it.

Any tricks of the trade?
Anyone got a pic of how the catch / spring mechanism works?

Thanks in advance.

Re: Brake Release..... Won't Release

Surface rust is normal for the mechanism. Might not be your mechanism, are you sure your rear brake shoes are not locked down?

Simplicistic design with a single pivot point. You can see the pivot retaining rivot stud head at the front. Return spring is behind the mechanism plate. Never saw one frozen. I have extras. The unit comes out easily, repair should present no problems.

Check your cables (3) under the car for being stuck..

ALso check the calipers in oder to make sure that all are working well, if the aforementioned doesn't pan out.

Jack up the back of the car and see if you can turn the rear tires.

Is it drum brakes or disc brakes??

Yes - saw the retaining rivet when I was playing with it last night. Sprayed it pretty good, no progress.

All new cables, but I'll check anyway. The parking brake sets and releases (manually) just fine... it's just the release mechanism / rod under the dash that is stuck.

I'm pretty sure the brakes are working fine... but I'll check them anyway.

Yes, I can turn them

Rear drum, front Disc, Original SS with nothing changed except wearable parts


All brake components are new... pads, shoes, calipers, etc. Had the drums turned... all have less than 3,000 miles on them.
