Wilwood mistake - need help

[Colin Frolick]

Howdy all. i'm a little embarassed and need your help. Last night I was mocking up brake lines for these 4-piston wilwoods on the rear of my car. i assumed the caliper used typical 3/16" lines so i blindly screwed one in... much later i realise you're supposed to use a banjo fitting with 1/8-27 NPT thread. the steel line fitting I used is 3/8" - 24 threads per inch, so it went in easily enough i assumed it was correct and didn't notice i was damaging the threads. so now what can i do. the threads aren;t that bad, though these are the brakes and of course safety is paramount.

i have some banjo bolts left over off a honda motorcycle that are a little larger diameter and could be made to work by re-tapping the hole, but then i'd likely need honda-size lines, but what i REALLY need to ask is - how is one supposed to plumb these? this is on the rear so flexible lines are not needed, but how do you connect a steel line to this type of port? or what kind of fittings / flex line am i SUPPOSED to use.

thanks in advance

Call Wilwood and ask for Mike Hamrick. Mike is a cool cat and knows his product better then anyone. 805 388 1188.

Sorry I can't answer your specific question, but why wouldn't you want flexible lines on the rear? For drums, I understand, but for discs - how are you going to remove the caliper to replace the pads with hard lines? I used a flexible stainless steel braided line as with the fronts.

Flexible lines to the rear calipers are the usual way to go. Calipers move a bit and a hard line is just asking for a stress crack. Also for pad replacement they are nice ;) . If the correct size banjo will tighten w/o stripping in the caliper just do that. So long as it tightens enough to not leak it will be fine. It wont fall out or anything. If it wont tighten the larger banjo bolts may be an option but correct sized hoses may be hard to find.

IMO the brakes are not to be second guessed (at least I would not want to second guess mine in a panic stop), a "qualified" opinion on whether or not the calipers are deemed unsafe should suffice. Should there be any questions....?? Bite the bullet man, and by 2 new calipers if you have the 12.19" x .810" 1pce rear rotors then you would need 2 of the 120-6806 calipers which retail at $124.95 each. I know my life, wife and kids are worth the $249.90 replace them if you have any doubts.

BTW the 1/8-27 NPT female inlets are pretty straight.....the male fittings that plug into them are tapered and correctly installed should have teflon taped wrapped in the proper direction (be sure to trim any edges to ensure smooth engagement and allow no debris to enter the caliper piston area) will ensure a tight seal.

Since the male fittings that plug into these calipers are tapered there is a pretty good chance you are okay once you install the correct 1/8-27 NPT pipe thread fittings.

P.S. We have the SS Flex lines for your car in stock $35 each.....Wilwood 1/8-27 NPT fittings are included at no charge as well as chassis side/hardline fittings adapters.

thanks for the input. i'm looking again at the threads in the caliper and i think with the correct fitting there should be no problem. life wife and kids are important

LTorres I'm giving you a call

correct me if I'm wrong here but 4 piston Wilwood calipers have a 1/4 pipe thead and you can use a fiting that will use a -4 or -3 flex line to a bulk head fitting that you now can fit you 3/16 steel line to
