Wilwood Problem

[Railroad]

I have the late model Mk Iv 20th Anniv with the optional IRS and big Wilwoods all around.
I was try to make a little progress today and install the hardline to flex brakets to the frame. While trying to install the rear flex hoses to rear calipers, I could not get the banjo bolts to feel good as they threaded in. I tried the other bolt and other caliper, same results. I guessed maybe they have an interference fit to maintain the tightness. After making a few more turns it was just to much resistance and I stopped. Too late to call FFR and Monday is a weekend away. The bolts are listed as 10mm x 1.5 thread. I have no way of knowing what thread is in the caliper. I have a very well stocked nut and bolt vendor close by, but they are down to Monday also. If I can confirm, I have the right bolt, I can get a tap and die and chase the threads, if needed. As usual there are 50 other places I can work, while I put this on the wait and see pile.
Thanks for any advise or input.
A friend loaned me his pneumatic riveter. That thing was sweet until it quit working. I think a stem got hung up. It will be definitely worth the time to get it running again.

Mine didn't use banjo bolts at the rear calipers. Came with an adapter like can be seen in the lower RH corner of this pic. This were in the rear brake kit from Wilwood as part of the 220-12092 Flexline Kit. Looking at that kit on Wilwood's site, the fitting is their part number 220-6412, and has 1/8-27 NPT threads. That's not going to work very well if you're trying to put in a metric bolt.

Thanks edwardb. I need to see if I picked up the front brake line kit and tried to use it on the rear. I will see if the front takes the banjo bolt fittings.

[edwardb]

Nope. No banjos on the front either on mine. I received the same exact fittings as I showed for the rear. The NPT threads into the calipers require thread sealant BTW. Only fittings in the entire provided brake components and lines where thread sealant is necessary.

Dont know if the anniversary kit would be any different than mine. I had the big wilwoods all around also. Front brakes were the same as EdwardB described for the rears.

The part # on the bag is 14493. I am not at the shop and my parts list is there. I am going to guess they sent me the kit for the donor brakes. I am seeing some pics of the banjo coupling on those brakes. The kit for the front has the 45* fittings like you guys posted. Looks like the rear kit should be the same as the front?? Thanks for replying, I sleep better when I get a handle on an issue.

Again not sure if it is different for the anniversary kit but my lines and fittings were in the wilwood box with the brakes that were drop shipped directly from wilwood. The only thing I used from the kit boxes was the piece to connect the parking brake cable to the parking brake calipers.

FF supplies part number 14993 with the 2015 IRS parts. But you're right. Those are for Mustang brakes. Both the front and rear Wilwood optional brakes have the flexline kit and fittings referenced above that should be used with their brakes. As stated, they are included with the rest of the brake components they dropped shipped to you. Use of the Wilwood flexline kit and fittings is described in the Wilwood instructions that came in the box.

I too had both the banjo bolts and the proper Wilwood fittings in my kit. As you did, I initially went with the banjo bolts as they were the first set of components I came upon (and what I am used to from previous experiences) when installing my rear brakes. I noticed too much resistance upon the initial few quarter turns, realized the mistake, chased the threads with a proper tap, and installed the correct fittings. I can't speak for you but I felt that I still had the vast majority of the correct threading left to provide a proper seat for the fittings.

Make sure you do not introduce contaminates in the calipers when chasing the threads. I chased the threads with wax on the taps, cleaning the tap after every small turn, and flushed the system to help reduce contaminates prior to installing the proper fittings.

[Railroad]

Thanks for all the good experienced information. I do not recall seeing the correct kit with the rear brakes. I did get my brakes with my original delivery. I will have to double check for the right lines and fittings.
I think the threads will be OK. I looked at the banjo bolts and the threads show no distortion at all. I know they are a harder material than the cast alum alloy of the caliper, but I feel good about it.
It is so good to have the answer to these things, just a click away. I appreciate it.

Wilwood uses a 1/8" NPT fitting there.

My IRS kit came w/ SS braided hoses w/ banjos that connect to the 2015 Mustang calipers. BTW, I re-used the factory bolts because they are 50% longer than the banjo bolts in the hose kit. I am sure FFR will swap w/ you.

The OP is posting about the optional Wilwood brakes. There are no banjos used for those, even though FF included them in the kit. As they did mine. The right parts are in the Wilwood brake kit, described in the Wilwood instructions, and pictured above: 220-6412 Caliper Inlet Fitting, 45 Degree, 3 AN male to 1/8 in. NPT male.

Wilwood 12.19" (Combination Parking Brake) part number 140-12049 accepts a Banjo fitting for the flex line. This brake combo is only for a solid axle (8.8) car. Sounds like FFR sent you the incorrect flex line kit for your brake package.
