yeah ive looked at your pdf (its very good and detailed) but im afraid its a short time solution if the corrosion wont stop.
Short term solution? Sorry I don't agree and I have the proof. If an overhauled caliper stays free for ten years without any further overhaul, and the next time it need's to be cleaned it's also very easy since it can be taken apart easily (since the items are not seized tight together) then you only need two overhauls to give you twenty years of problem free braking! I consider that far from short term and much better than even the new car market achieves. the caliper is very new and in very good condition
And there in lies the first problem. New calipers are assembled without any protection and deteriorate quickly. Any new calipers I have bought I strip first and rebuild them properly before fitting them. Most people simple fit a new part without thinking. and another thought, aluminium expand faster then iron when it gets hot, so the piston will get stuck anyway? or is this just to little to take in hand?
No that does not happen. Heat is also transferred and the individual components cannot be considered in isolation. I will repeat this again... Properly overhauled calipers can last ten years without further jamming problems and I know this for a fact since those that I have done on my cars and those of others have proved it. The original unprotected calipers did not last this long from new (I had my Murena from new) and similar calipers on later Espace and other new cars models corrode and jam just the same, as I have found and have had to change at work. (We had to replace with new at work as overhauling was not allowed, as I have explained before) Corrosion and things seizing together is common with new parts on vehicles because they will never assemble them with even a little grease which could be helpful - it's all down to cost and accountants! Let's face it, they don't even fill the brake reservoir in most cases as this saves them money - the dealer ends up topping the reservoir up and standing the cost since you cannot claim warranty on this! It is a typical 'cheat' factories use to reduce their costs!! Roy
