Rebuild Calipers or Buy Used?

Been doing a pad change and a simple job has turned out a bit of a nightmare - rear calipers on both sides are completely refusing to retract. Even bought a piston rewind kit but no joy. Peeled back the gators a little and it's all pretty corroded.

I'll probably keep the car another year or two, not worth buying brand new calipers, but just wondering what the best/easiest options are?

1) Looks like a piston rebuild kit is ÂŁ30 a side, is this an easy enough task?
2) Used calipers from breakers about ÂŁ60 each...but I'm guessing with around 7-8 years use on them they might not be much better than the ones I'm taking off.

On a related note, I've got a 2006 MkII - I read that 2001-05 have 283mm rear discs whereas 05-06 had 305mm, in which case if I bought calipers they'd specifically need to be off an 05 or 06? Likewise, are the calipers the same between petrol & diesel models?

I would suggest to get used ones. Do you get warranty on the used ones there? As opposed to getting the rebuild kit, its much more riskier. If the bore is rusted out & has pitted liner then the kit is not useful at all. Does the kit includes the piston? I am not sure if the models you have there has the same spec as the North American Models here. Here is the link. Hondapartsnow.com Compare the part numbers on those years. If they are the same its the same parts if not, they are different.

I'd steer clear of the rebuild kit unless you have access to some machining equipment, and are familiar with it. Also, you'll need a very precise press if you expect your piston to go back in straight. Don't expect the best results with a bench vise or clamp.

Have you verified it is the caliper by opening the bleeder and trying to compress it?

A set of rebuilt calipers with new flex lines and new brake fluid, would be how I'd tackle it. When calipers, flex lines and master cylinder seals start to go, they leave deposits in the brake fluid. I'd hate your new calipers to get a fresh delivery of worn seal and line sediment.

Thanks Otto - the rebuild kit did include a new piston, however, I've found a place doing rebuilt ones with 2yr warranty for not much more so was going to go for them. Only slight issue, they only list them as being for the petrol models.

I've just checked on the parts link and it seems the same part numbers for each of the models listed (though it's a little hard to tell, the US model codes are different from UK ones, and they don't mention if it's diesel or petrol). Can anyone confirm?

Dan - yeah, opening bleeder didn't do a thing!

Lings list both petrol and diesel calipers with the same part number so you will be fine. The US does not have diesels so you won't find info there. I recently did the calipers on my 05 putting innew pistons and seals and they are fine now, but for the amount of time spent de rusting them it would have been easier to just get rebuilt exchange ones.

Thanks Dave - I hope you're right! I'd asked a place advertising petrol calipers if they'd fit, I supplied my reg and they said they didn't but I'm hoping it's just the person making the compatibility database has been wrong.

I just checked the place I got my parts and they also list the same for both petrol and diesel only difference is for the smaller discs on the earlier models

In the US, buying rebuilt ones is the way to go. The parts suppliers take your old ones back and give you a credit for them.

Used? You already have used ones. ;-)

The price for new is astronomical. Dealer wanted $485 for a Scion caliper. Rebuilt was around $80.
