hxk494 Posted January 22, 2022 Share Posted January 22, 2022 Hi folks, I'm doing some work to my 110 brakes and need to replace the caliper brakcet - ftc3306 - I've fitted the new one using the existing bolts and I'm pretty sure these are wrong and should be longer as they don't come all the way through the threaded part of the bracket. It looks like they should be closer to 45mm in length rather than the 35mm that was in. Looking again at the parts fiche it appears that on the 110 the stub axle/calper bracket should be attached (per side) with 4 of M10 x 55 bolt (BX110111L) and 2 of M10 x 35 (BX110071M) and 2 of NY110047L M10 Nylock. This would thefore be 2 shorter bolts and nuts and the 4 longer ones going into (through) the caliper bracket but without nuts. Would anybody be able to confirm if this is correct? Serial is VA if that makes any difference I've attached a few photos which show the 35mm failing to fill the 4 threaded holes in the caliper bracket (but this is how it was attached previously). Thanks, Martin. Quote Link to comment Share on other sites More sharing options...
hxk494 Posted January 22, 2022 Author Share Posted January 22, 2022 though now having looked at BX110111L - https://www.lrseries.com/BX110111L-BOLT-M10-X-55-HEX-HEAD-NEW-REPLACEMENT I really don't see how that will work as the non threaded shoulder will meet the threaded caliper bracket after passing through the stub axle before it's tightened Really confused now!

hxk494 Posted January 22, 2022 Author Share Posted January 22, 2022 though maybe the longer shouldered bolt will work? this is sold as stub axle kit (DA3100) for 110 Sailsbury disc brakes from LA930456 and it has two shorter bolts, 2 nuts and 4 longer bolts. https://www.steveparkers.com/product/da3199-stub-axle-kit-defender-110-rear/ Quote Link to comment Share on other sites More sharing options...
western Posted January 22, 2022 Share Posted January 22, 2022 As the 110 parts book shows BX110111L M10 x 55mm IIRC thats what I used on my drum to rear disc conversion using the FTC3306 caliper brackets I can't remember if I put nuts on them or if they are just beyond the caliper bracket face.

western Posted January 23, 2022 Share Posted January 23, 2022 You can always extend thread longer on the bolt with a M10 thread die. or use fully threaded Hex head M10 x 55mm set screws Quote Link to comment Share on other sites More sharing options...
tommobot Posted January 24, 2022 Share Posted January 24, 2022 I'm looking for some bolts this for exact purpose... I believe, M10X 1.5 - LENGTH TBC @10.9 Does this sound about right? Quote Link to comment Share on other sites More sharing options...
