I just bought a rear end out of a 92 z28 It has posi and disc brakes, was wondering what these brackets were for? Im thinking the E brake cables go through them maybe?

These cars have no "E" brake that I know of; only the "service" brakes (the ones that stop the car when you push the pedal), and a "parking" brake.

Those are for the parking brake cables.

Parking brake? who needs that? So its not an emergency brake ? Hell if they are not going to help you stop in an emercency then why bother?

sofakingdom

Matter of opinion I suppose...

Just try stopping your car with the rear brakes only, with just that wimpy cable actuating them without power assist, in any kind of "emergency". Ain't happenin.

All that thing is good for, is parking. Isn't worth a steaming bucket of ... spit ... in an "emergency".

Take it or leave it. It is what is it. (and isn't what it isn't)

It was called a "emergency" brake b4 the hydraulic brakes became cool and it was put in place to please the powers that be.. The cars weren't as fast, heavy or powerful back then sooo a E brake could help stop ya in a panic situation.
Its either a P or E brake in my world, if your stopped and have a manual trans its a P-brake. If your brakes fail for some reason then the P becomes a E-brake. Will it stop you like the normal brakes will? Nope, but it will slow you down better than flinstone brakes ever will..

I would like to get the P brake working I suppose, I want to put in a manual trans and it would be helpful. Im kinda at a point in my build though that Im thinking of just putting the auto back in sheesh. Ive done so much to it already its starting to drain my pocket and my nerves.

Really??

Try a "panic" stop from the rip-roaring speed of, say, 10 mph. Measure the stopping distance. I think you'll agree once you try it under less than "emergency" circumstances, that if you REALLY get into some kind of "emergency", you're better off driving it into the ditch beside the road, rather than counting on THAT thing to actually do anything useful.

Heh after new rotors and pads (J65), recall pistons, cable adjustment etc etc, I managed to get mine to work as a parking brake. So long as the car is not parked on a heavy slope of any kind, like my driveway. If relying on this alone (ie not in Park), it will sit happily for a period. Then it might decide to go for a little excursion into the middle of the road when my back is turned

Over here we use the term 'handbrake'. Covers all options.

So should I or do I need to put some kind of poll out there?

Check this box if you think I should bother putting it back in
Check this box if I should delete the "handbrake" altogether

If it is not going to help in any way then **** on it I will juat delete it... Ive got enough *** raping going on with this rear end of mine lol. Now the guy says ohh sounds like the pinion bearing might be bad too thats another 400 . Jesus Christmas.

I use mine all the time. I don't rely on it 100% but if I'm on a somewhat flat surface and need to jump out quick the brake will hold the car. Mine does hold pretty well on an incline but I never fully trust it so I shut the car off and leave it in gear. Mine is a manual so I feel it is a necessity. On an auto not so much, but even on my auto cars I use the brake as to not overload the parking pin.

Its def NOT going to leave retina sized divits in the windshield.... It'll help slow ya down till they melt off....

Definitely hook it up and make it work.

Just be realistic about what it's good for.

Ok,bypassing the whole "hand brake" debate (thanks Treefiddy), I think those were fabbed up by someone. The 91 setup I have had the usual guides on the body and trailing arms. Never seen guides on the diff cover. Looks like they would hook on debris maybe.

TreeFiddy

Heh, we got foot-brakes too

Think the one on the left already did.

Yea I have mounting brackets on the chasis were the old drum brake handbrake cables went. I should be able to use them eh? I really dont like them on my diff cover like that. Looks stupid. Well... should be getting my Diff back tomorrow 6 Benjamins later. A complete overhaul. For that price it better be like new. Then comes the task of learning how to put in a rear disc brake system.

Those brackets are for a 93 and up too ?? 4th gen disc rear.
I have never seen them on a 3rd gen and I have several 91-92s with factory disc rears. That doesn't mean GM didn't put them on some 3rd gens. The factory diff cover for those brackets are a bit different to clear the brackets.
I'm wondering if the rear pictured is from a 4th gen.

Here are the guides on a thirdgen:

Could you measure the width of the rearend from axle flange face to axle flange face?

TTOP350

Thats a drum brake housing and shouldn't have those bolt on brackets from the factory. Drum brake housings (like the one pictured) have the large clip on the top driver side. Its for the drum E/P brake cables.
My guess is someone bought a 4th gen rear for the brakes and put it all on a older rearend..
The factory diff cover has notches or cutouts on the outer edge for clearance when using the wire bracket..

The OP or the pic in the link have the wire brackets on the wrong side. I "think" the OPs are correct, not 100% sure tho.

I purchased the fourthgen guides a few years ago, P/N 10285819 R and 10285818 L. Pic below seems to verify orientation (post #6):

10-4 It has been awhile since I have had a factory one in my sites.. I looked real quick for them on a parts site and didnt see them..

Ok so you guys are confusing me here.... Drum brake housing? I have disc brakes on the rear pictured. And are my guides correct or not? I would actually like to get new ones like in the link with the summit cover on it. Are those the ones I need and if so where do I get them? Also thanks for the other link that shows the new P brake cable being installed... I have to do all of that to mine once I get the rear end back and Im not sure what brakes or extra parts I need.

In the link JamesC posted up, the rearend is a drum brake housing.
Yours is disc.
I'm just wondering how wide yours is because I'm thinking it may be a 93-up rearend.

J65, TTOP. I converted the rear from the Delco-Moraine system to PBR's.

Its at the shop getting new seals and bearings, I am suppose to get it back today at 3pm I will measure it and let you know. It is out of a 92 z28 or at least thats what I was told.

BTW, Side,

I purchased the guides from the dealership using the part numbers that I provide above.

Are those the guides I should have? Those are 4rth gen. Oh well guess I will figure it all out once the rear gets put in.

If you're converting from drum to discs, the following FAQ discusses conversion, cables, combination valve and so on:

Thanks James, I just got the new rear in the car today. Looks pretty good I think. I still have to touch up two spots with paint and get the hardware for the sway bar. Then get the new calipers and P brake cables from ED and the combo valve as well.
