blairjj Posted January 20, 2010 Share Posted January 20, 2010 So in what surely can only be described as a complete act of idiocy, I decided to rebuild my 200sx rear calipers when I had them powder coated. I was inclined to do this as I was doing my front S12+8 and it "seemed" like a good idea at the time. These were Rock Auto rebuild specials that I got for like $30 They came apart easy enough: So at this point... right here: My spider sense SHOULD have been tingling... see that roller bearing in there? Here let me help out a little: it's part number 44130 in this diagram courtesy of Courtesy Nissan (NLA). It is a VERY special little bearing... one that is obviously expensive as later rebuilders bypassed replacing it and used bronze: So I know what you are thinking... why didn't he just leave them in there... I mean did they NEED to come out? So this is yet another thing that I have made peace with myself by pretending that the previous owner had done this. All of this brings me to my question for the forum: Any one ever replace this before? Here are some better pictures of the sizes of the parts in question: Powder coated caliper bodies are lonely: Quote Link to comment Share on other sites More sharing options...

Tricked Posted February 22, 2010 Share Posted February 22, 2010 I've done the same disassembly with another set of rear calipers with built in parking brakes. I left the bearing in, told the shop to take care not to get any sand blasting media in them, had the powder coated. Once I got them back, I had sprayed out the bearings with a cleaner and compressed air to get out any possible blasting media and the old hardened grease. I repaced them with grease, reassembled them and haven't had an issue since. Quote Link to comment Share on other sites More sharing options...
Tricked Posted February 22, 2010 Share Posted February 22, 2010 Are there torgue members that the clipers mount to that you are powder coating as well? Quote Link to comment Share on other sites More sharing options...

zcarnut Posted March 18, 2010 Share Posted March 18, 2010 Problem solved: Jay; It's looks like you have made some spare bushings. Any thought about selling a couple? I've got two 200SX calipers I'd like to save from my "scap metal box". Quote Link to comment Share on other sites More sharing options...
