Just looking for a little advice from anyone who has had their calipers powder coated.

i bought some braided hoses for my SV at ally pally and decided while I was in the process of doing the hoses I may as well get my calipers painted as we get alot of powder coating done through work and may as well get the rear stabalizer arm done too.

I want to remove all the parts tommorrow and was looking for any tips as removing the pistons and seals from the calipers and making sure they dont get any paint where i dont want it is what worries me :?

any advice would be helpfull

tips as removing the pistons and seals from the calipers

The easiest way to get the pistons and seals out is to pump them out with the brake lever. This is also messy as there will be brake fluid sputing out at pressure. This is not very pleasant stuff. Wrap the caliper in a cloth first.

Cheers for that Scoobs I will give that a go I have plenty of old t-shirts I can use as rags.lol

Any advise on how to block up the piston holes so as not to get powder coat in there, I read on one site that you should send them the pistons along with the caliper??

A good coater- and by that I really mean one that does a lot of work on bikes- will take care of that for you usually. But I think some would ask for the pistons.

Or you could pump them out as far as the oil seal, then drain the fluid using a plastic hose on the bleed nipple, take the calliper off the bike and THEN take out the pistons. That's what I do and find it far less messy. Just a thought that's all.

bigape, you seem well up on knowledge of working on calipers. do the pins, holding the front pads in, slide in and out or do they screw in. local dealer told me they screw in but i have never heard of this. serviced rear caliper and about to tackle front ones. :) have changed fluid, wanted to copperslip pins on front calipers.

The pins slide in are held with a R-clip. This is the same for the front & rear on a curvey. On a pointy the fronts are same but the rear i beleave they changed it to a pin with a socket head that screws in which makes for easier removal unlike the rubish curvey rear brake pins getting stuck.

As TSM stated they are pins that slide in and out. I seriously suggest that when you get them out, before you put them back in, apply a liberal coat of copper slip grease. This will help in the prevention of them siezing in place. Something that SV pins do very easily. If you can, get the pins changed for stainless steel ones. This can save you a lot of heart ache and effort if when you come to service them again.

All 650 front calipers have plain pins that are not threaded, pointy rear calipers have a threaded pin.

Well just come in from removing and stripping all the calipers, all went smoothly which was good, used low pressure air line to get the pistons out in the end which worked a treat.

Just gotta prepare them for painting now.
