SeaHawk Get your caliper from JRT Automotive from ebay. They are a fraction of the cost of Honda dealerships and are re-manufactured genuine oem by EBC. They are as good as new and Honda dealerships are happy to fit them. You will save yourself at least £200.00!

 

Good to hear of a happy ending, eventually.

 

I took a look at my rears this weekend for preventative maintenance reasons, to grease and to check the pistons etc. Both of my pistons seem to wind in freely until they're around ~5mm proud, at which point they continue to spin but won't retract any further. Does this sound normal?

If they are both moving freely i would guess that they are fine as the piston is not seized. As both of them do the same i would say its normal.

 

How are you winding them? You should use the special tool that pushes and turns.

If they turn freely they're fine. With mine I have to use a 9" plumbers adjustable wrench and lots of force to get them to turn.

 

I'm using a cross shaped fitting that I've welded to a old 1/2" drive socket, so I can push and wind. I suspect the end of the piston or cylinder is corroded and that's why I'm struggling with the final 5mm?

How does the piston work - if it's on a worm drive I don't understand how I'm able to keep winding the piston without it being pulled back in?

Cheers

It's not. The stud is connected to a bearing at the bottom (i.e. it's free to turn). So turning the piston only works when it's not too stiff to push in. When there's too much resistance the stud just spins round with the piston and it's not going any further in.

That's why you need the right tool that pushes against the caliper as it turns. I wouldn't worry too much; from the sound of it yours are probably far less sticky than most S2000s. But doing it the way you are you probably wouldn't be able to get brand new pads to fit.

 

Ah Gotcha. Yep - new pads were my thoughts exactly - they're not going to be fun to fit.
