henk Posted July 11, 2012 Share Posted July 11, 2012 I started today rebuilding my calipers basing myself on the article of Les Hanson that can be found in the archive however I noticed that contrary to what Les writes (The two seals are different - the upper one is solid and the lower one has a groove around the inside edge), the one under metal seal is the grooved one. Calipers come off a D1. I am aslo looking for the reference numbers of the rubber seals that sit between the 2 parts Thanks for advice, Henk Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted July 11, 2012 Share Posted July 11, 2012 That's the arrangement mine had. Main seal (lower one) is solid section, wiper seal (upper one that fits inside retainer ring) has a groove in it. The gallery seals for the 90/110 calipers I did are part number 17H8764L. Other ones are RTC1137 and 3851-739. See links for nominal sizes, measure your old ones to see what size you need. Quote Link to comment Share on other sites More sharing options...

reb78 Posted July 12, 2012 Share Posted July 12, 2012 I think it was a typo in the tech archive thread. The 'wiper' seal is the grooved one, the lower/fluid seal is simply a solid ring. Quote Link to comment Share on other sites More sharing options...
henk Posted July 12, 2012 Author Share Posted July 12, 2012 Maybe good to add this in the tech article of Les together with the gallery seal references? Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted July 14, 2012 Share Posted July 14, 2012 I concur, this is useful info missing from other write ups. Mo Quote Link to comment Share on other sites More sharing options...
JST Posted July 25, 2012 Share Posted July 25, 2012 i concur, wiper seal has the groove which is closest to the disc. on another note, i have given up rebuilding calipers. by the time you have the seals and pistons i dont think you are far off the £30 for a new caliper anyway.
