Washing Brake Calipers
Is it OK to wash brake calipers in soapy water prior to painting and installing the seals and pistons??

Best thing for them before painting, but use some brake cleaner first to get the oliy stuff off.

They were in the electrolysis tank to get all the crap off. I then bought some recon ones and they are in worse condition than my old ones!
I'm going to recon my originals because they are in better condition.
They are already in rec oxide and I've just blown the pistons out and they are in excellent condition.
I'm going to wash them, dry them in the oven then give them some Hammerite

Sounds like a plan - should look good when they are done

All you need is some washing soda, a car battery charger, a piece of steel and a plastic container!

I electrolysis'd my calipers by hanging them into the tank by the rubber hose. Everything intact, just straight of the car, cut through the pipe
with a hacksaw and into the tank.
The electrolysis doesn't attack anything except rust. I used caustic soda because I had some around and the tank was outside. I did that over 9
months ago and I've just took the caliper apart today and there is no rotting or anything bad.
I'm reconditioning them because I split the dust cover with the wire brush! and to make them look nice. :-)
Theres no need to remove anything before the derusting process.
