Default Caliper and bleeding questions?

I plan to get my calipers powdercoated and I was wondering if I should take them apart before dropping them off so that they dont damage anything when they blast or coat them? I havent looked at my caliper just yet to see all what I can do as far as taking them apart goes, but I just wanted to know if thats a good idea or not? Is it hard to take them apart? Is it worth it? Will I have to buy anything once I removed it? Meaning, on some stuff when you take it off you really shouldnt put it back on, you should replace it with a new one. (seals or something of that nature) To fully remove the caliper, you just take it off from the rotor and disconnect it from the line, right? Will it have pressure in the line? Will the fluid gush or just pour out? Is there anything that I should be careful of when taking it off? Then I will need some tips on bleeding the car system. What all needs to be done? Just reconnect the lines to the caliper, put them back on the rotor, put everything else on and you are ready to bleed? I will need an extra person to do it correctly right? Is it possible to do it yourself? So basically what you do is pump up the brake pedal, hold it, and release the air out of the caliper release valve and repeat the steps? If you could please, correct me or fill in anything that I left out. I really never bled a system by myself, I was usually the one that just pumped the pedal, so I really dont know what to do on the other end of the job. Thanks

I dont know where about to get the information about the calipers. I dont really need to know how to disassemble them or to assemble them, I just need an opinion whether or not I should tear them apart before I get them blasted and powdercoated. Thanks

They will need to be disassembled and the bores need protected from any abrasive media (bead blasting, polishing, etc) or the calipers will likely be junk when you reassemble them (and don't powdercoat the pistons....no paint, etc). Good Luck!

They told me that they mask everything off, do you think that I should leave them as they are or take them apart? I really havent looked at them yet, so I dont know if taking them apart is going to give me a better surface to cover or not. I just would hate for them to mask them and when they are done with the pieces, you will able to tell where they did so. I want them to be professional, precise, and accurate. Do you think with the blasting and coating that it will cover most of the rough texture on the caliper? Or do you think that I should sand them down before I take them in? Thanks alot

If the shop is "Professional", they should do fine work. You will have to tear them down to clean out the grit, so I'd send them that way. Just my thoughts.

The cheap plastic one.

I've heard the metal version is much more durable.

You have to remember, though. It was being used on 5 or 6 other cars with similar intervals ... once every 6 weeks or so.

It got a work-out ...

I just found out today that I will have to tear them down before I drop them off. Will I have to buy a rebuild kit for the calipers once they are disassembled? Or will I be able to reuse everything that came off? If I do have to buy a rebuild kit, where can I get one? How much am I looking at for the kit anyway? Where can I find a how to write up on how to disassemble and reassemble a caliper? Thanks

I've never had an LS1 caliper apart, but most have some kind of seals/o-rings. These may not withstand the baking part of the powdercoating process. I would definately not take a chance here. Buy a rebuild kit from GM. The kit should contain a parts list and instructions. And if the calipers have a rough texture, have your coater put the powder on heavy.

So I take it that I would get a rebuild kit from a dealer, if so, do you have any idea what Im looking as far as price go? Is it hard to disassemble and assemble the caliper? Do you think that its worth taking apart to powdercoat? Thanks

NVMySS,

There is usually a reason for the information that you receive in these posts....it just isn't often clear at the time. Sometimes you'll get the right answers, even if you ask the wrong questions....However, I don't have the site information you need (I don't think, I'm not sure which site it was). Good luck.

FWIW, I'd not bother with powdercoating calipers...I'd upgrade to a Z06 brake kit and use the Z06 calipers that already have the work done for you (if it all works out, you'll have pretty calipers, if not, you'll have a leaking mess and brakes are "somewhat" important)...just my thoughts. I think Mitch is running that same kit......

P.S. I wasn't trying to belittle anyone with that last post, I reread it and it sounded worse than I thought.....No disrespect intended....

What all has to be done to convert to ZO6 braking? Can I just change the caliper and pads? If so, will the brake line fit in the tap that originally fit in the stock calipers? Will it bolt right up where the stock one bolted in at? Where can I get them at? How much am I looking at spending for the conversion? Thanks
