Changed out rotors, pads, ran into a problem
Gents, thanks for taking the time to read this. I changed the pads, and rotors on my 06 over the weekend. The front went smooth, put it back together, took it for a drive, and everything was ok. Moved on to the back, had a bit of a problem getting the stockers off, but finally got them removed. Lowered the eBrake, and give 'em a quick (light) tap with a hammer. When going to reassemble everything, I couldn't get the new rotors on. So I adjusted the parking brake "star" all the way in, and it made the rotor go on easier, still wasn't easy to put on, but at least they went on. After getting the car back together it's obvious that the parking brake shoes are against the rotor as the car won't roll on its own, and when you let off the gas it comes to a quick halt. I haven't driven it, that was just pulling it back and forward in the garage. I'm fairly sure I'm going to have to pull it all back apart, is there any advice/tips/hints you guys can offer for this? Sorry for the long winded question, and thanks for your time.

I am curious as to why you couldn't get the new rotors on if the old rotors came off. At any rate the parking brakes are usually self adjusting. If you back up and hit the brakes they usually will adjust...it may take a few times. At this point though you may have to take the rotors off and adjust them but I am wondering if they will be difficult to remove if they are as tight as you are saying.

It appears that it's mainly on the passenger side, so I'm going to pull it apart first and see if anything is obviously wrong. Although unless there is a switch under the rotor that says "make brakes stick", and it's flipped to on, I doubt anything is going to jump out at me. lol
Thanks again for the reply.

The new rotors may have a slightly smaller ID than the old ones so the adjuster needed to be adjusted in. Sounds like you need to go a little bit further on one side.
I think the self adjusters only work one direction and may not reduce the drag (can only increase the braking force).
Good luck!

Your problem sounds like the new rotors are not finished properly inside the drum. If you had to force the rotor on with the PB shoes completely retracted the drum interior diameter is too small.
Parking brakes do not self adjust. They are adjusted by using a gauge that measures the inside diameter of the drum and transfers that reading so you can adjust the outside diameter of the shoes. If they brakes are close to tight then you might be able to adjust them by pulling up on and releasing the parking brake handle 3 times.

Bill, you and StKnoWhere are dead on. Thank you very much for the help! I've had an insane week at the office, so today is the first time I've looked at the car. I took the old rotors back to the garage, put the brake shoes back on, and it slides over fine. So I measured the new rotor and the inside is definitely smaller than the factory one. I purchased them from TPS Motorsports, I wonder if they'll take them back (swap them out) if they're obviously defective.
Thanks again for the help everyone!

I'm sure Mike at TPS will correct the problem for you. He is a stand up guy just don't go ballistic with him, which if never a good negotiating tact anyway.
I believe for the performance rotors, in the rear, bigger brackets are required. And I would assume it would be included in the kit.

I got your email late last night and wasn't able to get back to you. Some family was in town so I had to entertain them...
The rotors you have are defective and we would be happy to exchange them for you and get you a set shipped out ASAP. I'll make sure they are shipped expedited freight so you'll have them shortly.

Hey everyone, thanks for all the help/responses to my thread.
Medicdiver, I purchased these rotors http://www.tpsmotorsports.com/tps-c5...1997-2010.html and truthfully, I wish I would have purchased the Z51 brake upgrade. Looking back, I really wish I would have spent the extra money and gone with them instead, stupid move on my part, but I guess it's a little late now :\
Donald, I'll be curious to see how your upgrade goes. The entire process really isn't that bad, and the looks/performance will def be an improvement over stock I'm sure! For the record, you've really got to cowboy up on the caliper mounting bracket bolts, they torque to like 125 ft lbs.
TPSMak, I sent an email to Jason I believe it was on Aug 13. I assume that's the email you're referring to in your post below. I really appreciate your response to the thread, and your attention to my problem. My name is Jonathan, not Jim, BUT if you help get my vette back out on the road you can call me whatever you'd like LOL.
Thanks again for the help, I really appreciate it.

Mike, I'm not sure if you're receiving my emails. I sent one on the 13th and another on the 18th and received no response. I thought you might see this message in case the email address I have "MikeM@TPSMotorsports.com" is wrong.
I haven't heard of, or received any replacement parts and I was wondering if there is anything else I need to do to get them sent out.
Thanks for the help,
Jonathan

John,
I just let you a message on your cellphone... the rotors are being sent out to you Priority Mail so you should see a replacement set by the end of the week, If you want to call me back I left my cellphone on your voicemail.
