Motschrocker Posted July 31, 2014 Report Share Posted July 31, 2014 Hello, I have a 66 roadster with front disc brakes from a 1973 datsun 610. They are fuctional but i do not feel supercomfortable with them. I cannot find a set of calipers anywhere. Anyone have a lead on where i could buy or an affordable way to rebuild them. Maybe a step by step guide? Any help would be great Joshua Quote Link to comment
mklotz70 Posted August 1, 2014 Report Share Posted August 1, 2014 I'd like to see pictures of that setup if possible. Did you check rockauto.com? Quote Link to comment

Rockauto and every other site i checked does not have them. I found some rebuild kits though so maybe i will just have to attempt that on my own. Quote Link to comment
banzai510(hainz) Posted August 1, 2014 Report Share Posted August 1, 2014 arent they the same as a 510? ck rock auto and x ref the part numbers. Lots of 510 calipers out there in junk piles Quote Link to comment
mklotz70 Posted August 1, 2014 Report Share Posted August 1, 2014 Thanks for the pics. It showed me what I wanted to see. You're using stock roadster rotors/hubs and 610 calipers. I'm pretty sure you can put volvo calipers on there....might need to shave the diameter of the rotor down. http://www.311s.org/pmwiki-311/pmwiki.php?n=TechSection.VolvoCalipers If you think about going this route, I have a pair of the calipers already drilled and I have the block off caps so that you can easily run one brake line. I just checked myself.....rockauto does list calipers for the '73 610. Did you look under Datsun or Nissan? Check 311s.org They've got tons of roadster info. There's a couple of vendors that sell the stock rotors......for A LOT of money!!!! What do you consider affordable? I do roadster kits...you can take a look at those and see if they fit the bill. www.bluehandsinc.com Quote Link to comment

Lots of 510 calipers out there in junk piles according to RA....they match up with 411, 510, and 710 .....so you might contact EagleAdam on here....I'm pretty sure he put new 710 calipers on Jessi's wgn just before he swapped over to the other setup I did.

Motschrocker Posted August 2, 2014 Author Report Share Posted August 2, 2014 Thanks last i checked rockauto had them listed but not acthally in stock or you could mail them in for a rebuild i will try and cross reference the part numbers and see if i can find some from another model tjat would work. For nkw i wanna use the previous owners set up and just bolt on a new set if possible if not i may try another modfied setup. Quote Link to comment
mklotz70 Posted August 2, 2014 Report Share Posted August 2, 2014 Calipers are super simple items. If you take yours apart and the bore and cylinder are nice and clean with no pitting, clean them up good, throw in the rebuild kit(new seals) and call it good. Quote Link to comment
banzai510(hainz) Posted August 2, 2014 Report Share Posted August 2, 2014 I don't think 710s will fit early 610s yes what I remember most people throw them away when they upgrade. I think I had 2 sets and gave them away. Just ask around on here and maybe somebody has a set Quote Link to comment

If you take yours apart and the bore and cylinder are nice and clean with no pitting, clean them up good, throw in the rebuild kit(new seals) and call it good. I have not cleaned pistons or bores. How would you recommend doing this? Steel wool? Soft cloth and some rubbing compound? I ordered new seals today. Quote Link to comment
mklotz70 Posted August 5, 2014 Report Share Posted August 5, 2014 If the inside is smooth and shiny, just replace the rubber parts and reassemble. Lube them only with new brake fluid. I did this vid awhile back. It's a bit long and of a different caliper, but it will give you an idea of what's inside and how to get the rubber parts out and back in. If the bores are pitted, I'd get new calipers, but you can use a hone to refinish the bore.....here's a quick example.... I'm sure with a few minutes on google or youtube you'll find better info.

Ratwagon1600 Posted August 5, 2014 Report Share Posted August 5, 2014 I have not cleaned pistons or bores. How would you recommend doing this? Steel wool? Soft cloth and some rubbing compound? I ordered new seals today. This is exactly how I clean caliper pistons. If there is slight surface rust I may also use some rust removal liquid. Following cleaning, give everything a thorough rinse in methalayted spirits. Methalayted spirits does almost exactly the same job as rattle pack brake cleaner, and is way cheaper too, therefore making it a perfect Ratsun alternative. Quote Link to comment
