2000 Camaro SS

Is there a known problem when changing a 2000 Camaro rear end that has Traction control and anti lock brakes with a 12 bolt that has neither? The 12 bolt came with 93 LT1 brakes. When I put the brakes on they never let they just stay on.
Would the anti lock brakes be giving me a problem with keeping the brakes on?

I don't really understand what you are asking - but a couple of points

You of course lost ABS and traction control - since your car was a 4 channel setup you can make it work again using the proper caliper mounting plates and sensors - I would suggest doing that - you will need to switch back to your LS1 rear brakes more than likely though.

You will have lost your parking brake unless you converted that to LT1 style - it uses a caliper clamp that directly engages the rear caliper while the LS1 uses some semi-drum setup.

Thanks for looking into the question. I gave up my SS brakes when I went to a Strange 12 bolt set-up. I already ordered Wilwood Pro Street brakes with e-brake. To be exact at this time I have a set of 1993 LT1 rear brakes on the 12 bolt. I really need to drive my car as I just finished a great deal of work on my engein, clutch, and more. I need to get some A-tap readings at WOT. But every time I try to drive my car when I apply the brakes the rear brakes stay on. Locked up. The only way to get them to let go is to take the tires off this relieve the pressure and the brakes let go. I'm wondering if this is caused by not having ABS brakes on the car. I do not have any 4 channel set up or nothing. The car is VERY close to being 100% drag only. It will never be driven in the winter or rain as I have a spool and also a modified scoop to intake air just under the nose of the car. https://ls1tech.com/ubb/cgi-bin/ulti...;f=24;t=000270 I guess I need to know if there is anything else that I need to do to make the rear brakes work. I'm thinking when I get the new brakes installed my problems should go away. I don't need traction control or ABS to work. Any suggestions will be appreciated.

I installed a 12 bolt that wasnt set up for ABS or TC. I used my factory brakes though. My car works perfect without ABS or TC, no problems whatsoever. My ABS inop light stays on, thats about it.

So from what it sounds like to me whenever you engage the brakes your rear calipers stay locked up, and you have to remove a wheel (thus freeing the rotor) to be allowed to turn them at all?

You can pull your abs fuse to ensure that isn't causing problems, but this sounds more like some sort of mechanical/fit problem - when you torque the rear wheels down completely but before you engage your brakes can you turn the wheels?

Yes the wheel will turn when I torque the wheels down. I have the rear of the car up at this time...I put the wheels on, I then can spin the tires....I put the brakes on and that's it, the wheels will not turn until I take the tires off again. I'm thinking that the off-set from the rotor to the calipers are not correct. (Once again I bought the rear used off of a guy and I'm thinking I was not told everything about this rear end) So with that said, I don't know if the brakes on this rear are REALLY the brakes that are supposed to be on it. I'm thinking not. The rotors have been turned down to a 11 inch diameter, I was told for light weight. As I said I have a set of Wilwood on the way mad to the specs needed to run on this rear. But I need to get some runs soon to tune the car before the track opens for the season. What if I took the rotors off put a one inch block of wood between the brake pads and then wired them to the axle. Would the front brakes have enough stopping ability to stop the car by themselves? Would I be asking for trouble trying this? I was told by Wilwood that it will be at least 10 or more days before the brakes bet here.
I'm going to try pulling the fuse to the ABS to see what happens.

Well if the 12-bolt was out of a '93, then that is your problem. The axles are about 1/4" difference in length than the '98-up cars. The only way to make them work is to use your axles. You will have to swap them out. So sad, but true <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

This is why your brakes are binding. Had a friend went through the same thing.

I bought this rear knowing it is shorter because I'm running 28 inch by 10.5 inch slicks and I want them to be inside of the fender lip as per regs. I'm really just wondering if there is a problem using my master cylender and brake line on a non ABS & non traction control rear.
Thanks for all the responces.

Since everything came together as a unit I think it should work also. Since you are getting new rear brakes I would wait - but right now it almost sounds to me like the rotor might be incorrect for the application?

The only other situation I could think of would be with regards to the ABS or TCS - but pulling the fuse for both of those should answer that question

Ummm, just a thought, but since it's a used rear, and all the stuff came together. Assuming that you were actually told the truth about the rear, one thing seems kinda obvious to me to check that noone has suggested so far...........are you sure that there is no trash in the lines? maybe something blocking the line just enough to keep the pressure from releasing? May not be the problem, but it could be.
