Hi guys,
I'm new on this forum. Well actually i've been following it for quite a while, but i've just bought a MK Indy kit from the dutch
importer, so I'm eager to start building! And probably will need lots of advice!
But first I have to do some cleaning, as I have some very rusty parts in my garage. I've read the threads on electrolysis and it sounds very
good. Does anyone know if it's save to put my calipers in if I first remove the seals and piston?
Cheers
I have so I hope so! I put it in with the seals and pistons (these are going to be replaced) with a blead nipples in both outlets/inlets to stop water
getting in the piston boars, I figured that on the car the bit's now left exposed get wet anyhow..

Personally I'd buy new calipers - I got mine for £28 each after spending ages cleaning the old ones and eventually realising they weren't
worth bothering with.

as bluemoon said, I'd keave the old pistons/seals in and would even plug up up all the holes as I woudn't want to be electrolysing the
internals.

Phosphoric Acid is what you need (in a slightly higher concentartion than they put in Coca-Cola!).
It'll dissolve the rust leaving you with clean steel. If you are going to paint the calipers I suggest you bake them in a gentle oven as the
iron is porous. All the grease and cr*p will 'sweat' out. HTH
Anyone you recomend?
so whitestu, where did you get the calipers from??
This is incredible but what has worked for me in derusting all of my parts is a mixture of 1 part blackstrap molasses (the kind you feed horses) mixed
with 8 parts of plain water. I keep in in a 45 gallon Rubbermaid trough with a lid outside. If you take the paint and oil off and give it a rinse
before dropping in the mixture, the part will come out perfectly clean in about a week or so. The mixture lasts for months (although gets pretty
cruddy). Once you are done with it, you hose it into your lawn as it is nothing more than smelly sugar and iron oxide. Only the rust is affected. I
have used in on rusty brake drum and with a wipe with SOS pads, it was natural cast rust free metal.
Honest, it really works! I wonder if it would work better with electrolysis applied, but I have not had a need to do it yet.
Zetec 7 who posts here has seen it and can vouch for the process.
