Mo Murphy Posted September 14, 2010 Author Share Posted September 14, 2010 Thanks James, how did you find them so quick ? I searched but obviously with the wrong combo of words, must be me age ... Mo Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted September 14, 2010 Share Posted September 14, 2010 Well I knew of the suppliers, just chose three that I knew stocked 'obscure small parts' and punched in the part number. Googling the part number is a good way to find suppliers of a part too. See the list of people selling it below! http://www.google.co.uk/search?hl=en&q=17H8764L Quote Link to comment Share on other sites More sharing options...
western Posted September 14, 2010 Share Posted September 14, 2010 google lots of suppliers to chose from even LR main dealers can get these. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted September 14, 2010 Author Share Posted September 14, 2010 Mmmm times have changed ! In years gone by these were impossible to get hold of and I quite wrongly assumed that this would still be the case. Still always splendid to be proved wrong Mo Quote Link to comment Share on other sites More sharing options...
western Posted September 14, 2010 Share Posted September 14, 2010 no problem with splitting caliper for rebuild provided the corect seals & care is taken, for vented calipers you'll need 4 seals per caliper to seal the spacer block fluid drillings to each caliper half, for standard calipers just 2 seals for each caliper are required.

Mo Murphy Posted September 18, 2010 Author Share Posted September 18, 2010 OK chaps, spot of bother Have bought above seals 17H8764L from LR series who sent Britpart items. Trouble is that the seals are too small being 13mm compared to the 16mm or so of the originals. My question is, are the seals the correct size for the part number, in which case I've ordered the wrong bits and I'll have to take the hit on that one OR should the seals be 16mm and the items supplied are undersize in which case they go back to the supplier. If they are in fact correct does anyone know the part number for the larger seal ? A rather poor phone photo to illustrate the dilemma. Original seals at the top, new at the bottom.

western Posted September 18, 2010 Share Posted September 18, 2010 they maybe small new, but once the caliper parts are bolted together the seals should sqaush down to fill the recess/seal the fluid drillings. more seals here but diameters not given. & here page 16, bottom right of page also used on mini car calipers.

Mo Murphy Posted September 18, 2010 Author Share Posted September 18, 2010 Ralph, these won't fill the recess even when squashed and will obstruct the drillings, they are simply too small. The seal only stands proud by a fraction of a mil and the face of the other half of the caliper is flat so there's no way that this seal will seal the recess properly. Have any of you other chaps found seals to be undersize when you've changed them ? Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted September 18, 2010 Share Posted September 18, 2010 Weird, even on the Brit-car site they're shown next to a ruler and they look about 13mm. They're the only ones listed in the parts book as far as I could see Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted September 18, 2010 Author Share Posted September 18, 2010 This is really odd isn't it, James. Still I'm sure someone who's changed them before will be along at some stage and can yay or nay them based on their experience. Mo Quote Link to comment Share on other sites More sharing options...

I had the same trouble on a mates and ended up fitting new calipers as it was less hassle Quote Link to comment Share on other sites More sharing options...

Have any of you other chaps found seals to be undersize when you've changed them ? very strange, maybe there is a duff batch out there. same number for Discovery & RRC front caliper half seals discovery rear caliper half seals are RTC1137 -- could be incorrectly identified on the package you got.

Mo Murphy Posted September 18, 2010 Author Share Posted September 18, 2010 Ah now that's interesting Rusty, and would explain why the bloody things don't fit Ralph, So there are 2 different seals, well found ! That's a discovery half in the picture which is the same size as my rangie calipers which have been rebuilt so it seems I need RTC 1137 for Disco rears. Splendid. I'm sure I'll find a use for the others somewhere Dreading opening up the front calipers now, probably find I need yet another different size !

cackshifter Posted September 20, 2010 Share Posted September 20, 2010 I think Keith Gott used to sell the correct seals, might be worth a call; IIRC they don't have a part number. Nigel Quote Link to comment Share on other sites More sharing options...
ldtopham Posted September 20, 2010 Share Posted September 20, 2010 Mo, Is it the rear calipers? I ask because I split one of mine when refurbing them last year and could not get the seals from anywhere. Mine were the ruber cylindrical type and not o'rings. I ended up buying a replacement caliper from Keith Gott and retro fitting stainless pistons to the new caliper. The cylindrical seals were used on my 1997 110 Defender 300tdi original rear Lockhead calipers. I didn't split the other 3 after the finding of no replacement seals. If yours are defintely o'ring type seals ignore all the above. Regards, Lee Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted September 20, 2010 Author Share Posted September 20, 2010 Lee, they are square section O rings, like a slice from a bit of rubber pipe. We'll see what RTC 1137 look like when they come. Mo Quote Link to comment Share on other sites More sharing options...
ldtopham Posted September 20, 2010 Share Posted September 20, 2010 They sound just like what I was looking for . I hope you find what you need. If not please post a reply with your findings to warn other DIY'ers of the potential £££ for aiming to do a job thoroughly Cheers, Quote Link to comment Share on other sites More sharing options...
