So I am having a problem with my front ITR Nissin brake calipers. I am having very small seepage at the brake line fitting holes. I now have the fitting bolt torqued 10 ft lb over factory spec of 25 ft lb and it still seeps. I bought these calipers from rockauto.com which are rebuilt by Centric brake parts but they are OEM Nissin calipers but what I notice about these Nissin calipers is there are some ridges/rings around the brake line fitting hole, it is not smooth like the 98 civic ex Akebono calipers. I already returned them once but still the same problem. Can anybody with ITR calipers who has them removed from their car verify if their calipers have these same ridges at the brake line fitting holes? Check out the pictures

 

Did you use a NEW crush washer on both sides of the banjo? Those ridges should actually improve sealing.
