stephen grant Posted November 29, 2010 Share Posted November 29, 2010 As above. Can't stop a very small weep from somewhere around the lower washer, where the banjo bolt goes into the caliper. Apart from trying subtly different washers, with subtly different torques, is there anything else I can do to try to stem the (gentle) flow? stephen Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted November 29, 2010 Share Posted November 29, 2010 Is this a new build, or a leak that has developed on an older car ? Check the mating faces that the washer sits against on the caliper and the bolt. Look for scratches on the washer. If a new build, it it actually coming from the caliper itself ... recalling similar recent posts. Link to comment Share on other sites More sharing options...
stephen grant Posted November 29, 2010 Author Share Posted November 29, 2010 It's a new caliper on an old car. Hope it's not coming from the caliper How do I tell? When I looked, the mating face on the caliper looked ok, but I suppose I didn't look that carefully... s Link to comment Share on other sites More sharing options...
Bricol Posted November 29, 2010 Share Posted November 29, 2010 If they are copper washers, anneal them and try again. Bri Link to comment Share on other sites More sharing options...
stephen grant Posted November 29, 2010 Author Share Posted November 29, 2010 Heat it up and then drop it in a bowl of water? Will give it a go this evening, thanks stephen Edited by - stephen grant on 29 Nov 2010 12:41:39 Link to comment Share on other sites More sharing options...
u01rsb Posted November 29, 2010 Share Posted November 29, 2010 I had it leak at this point once caused by damaged thread on the caliper after a crash. Sent it back to AP and they heli-coiled the thread which now is as good as new. Hope it isn't as serious for you, but there is a solution if you need it.

Bricol Posted November 29, 2010 Share Posted November 29, 2010 Annealing - yes you can do that with copper, although I just let them cool naturally. Bri Link to comment Share on other sites More sharing options...
