Just went to fit new pads and discs all round, and the front left caliper piston refused to wind back in.
​​​​​​
Clearly the caliper needs a rebuild/overhaul, and I certainly don't want to swap it with a pattern part.

Can anyone recommend a place I can send my calipers off to get refurbished or exchanged for genuine Nissin units?

Thanks

Most of the remanufacturers will send you a new one, and then ask for yours in exchange. Big Redd will do what you want. Bigg Red

Just in case it solves your issue... Front calipers down 'wind' in, they just push. It's the handbrake mechanism on the rears that requires you to turn the piston to retract it.

Just get the refurbished kit and a rewing tool and do it yourself. Much easier that people make out, especially on your second go! Can refurb both for less than £40!

Just realised it's the front! As Chris said, no tool needed. Just grab yourself this:

and away you go. Pop the piston out, clean it up, new seals and pop it back in! The main seal is a bit of a drag to get on, takes some time to get it seated properly.

Thanks guys, I'll put them on the workbench first and see how bad they are.

​​​​​It would be nice to give them a full refurb and paint, but if it's a simple piston job then I may just well do it myself.

I'd like to change the just the piston and seal on my rear callipers, the pistons turn ok but I'd prefer them changed as preventative maintenance. Worth doing or just replace?

I'm always for the DIY route, and this is a good how-to to get you started with the rear calipers, if you choose that option. As said above it's fairly tricky seating the main seal/boot, but a bit of patience will get you through it, and you'll be a pro next time! Plus once they're off you can paint them red and gain a few BHP!
