A lot of times, those bladders go bad. GM wants $800 to replace them (parts only). When I refurbished my seats, I replaced those bladders with some medical bladders that are a little more stout that the stock ones. They work like a charm and give excellent support. I also reinforced my seat but I didn't buy any kit. I just made it up. It's funny how a kit mysteriously showed up on Corvette Central. You can make your own for less than $10 bucks. That's some serious Corvette tax that they are charging!
Here are the old bladders and the bladders that I used as a replacement. The old, leaky ones:
The replacements (cost was around $49)
Here's how I reinforced the seat. I covered the fiberglass edge and taped the hell out of it so that it would no longer bust through the bolster after replacing the foam and leather:
For the bottom, I bought some really hard carpet like you would find at the front door to the unemployment office and laid it on the springs. That was over 3 years ago and my seats are showing no wear in those problem areas. I drive the hell out of my car so it gets a lot of use.
Don't pay that Corvette tax!
Junkman2008 - I just took my C5 sport seat apart and found all the bladders are broke. I found a source for ADC bladders but I do have 2 questions: What size bladders did you use??? and How did you fasten the bladders to the plastic bladder support??? Your solution is be far the best I have seen for bladder replacement, just need a little clarification on the above questions.
Thanks for sharing you ideas with us rookies.
The sizes are listed on the boxes. I bought 2 of each, an adult and a child size.
I believe that I used Gorilla Tape to hold them in place but it has been so long that I can't remember. I need to remove that seat cover again so maybe I will remember to look at it when I do. Once the seat is put back together, they ain't going anywhere.
I find the repair kit is exactly what I wanted. It has everything I needed and has instructions.
The price you pay for ANYTHING is more than the cost of the raw materials. And, yes, you can go out and buy the raw materials for less, but the kit save me time I don't want to spend looking for the right materials comes right to my front door.
Its like a friend of mine that complains about the cost of everything including a pizza. Yes, you can buy all the stuff for a pizza for a lot less than you can get it at Domino's. But it cooked an and ready to eat.
What else is there to know that ain't covered in that link?
Hi Junkman! Doing well?
i did the deed on my drivers seat, I have not read the entire post but I assume your question is about the seat repair. Here's what happened on my end, I did the repair not too long ago:
small hands and patience helps on the electrical connections, the Ms helped. I did not determine if the seat mounting nuts have a torque....I just tightened them down. You have to be careful with the 3m glue...off your hands, wear a mask and eye protection, I held my breath any way and left the area to breathe, spray in the proper place and do a dry run on how you place the ballistic mat...if the mat touches the glue, it stays! Prepare a nice area to work on the seat, I put out some horses and plywood sheeting. Might as well clean the covers while the seat is out of the car. I could not find the small size bull rings to set the cover back on the seat but the next? Size up was okay, now have a new tool, bull ring pliers!! If the button eschucheon is broken buy a new one....I found two broken areas on mine. I put the jute? Pad on mine, the seat feels great now, what an improvement. Oh yes, I also placed some ballistic type material on the L edge of the seat...the metal also cut into the seat bottom foam, again with the fantastic ! Glue. An easy way we removed the seat back handle: We used a 2" long needle ( needle thin) nose pliers ....the nose of each end was pressed against the tips of the C clip and off came the handle, easy peasy. As far as I know there is no fix for the seat back that pops out of place if your back presses hard against it while adjusting your man stuff. The seat back handle pops the seat back in place. I am really pleased with the outcome of project.
