STANG KILLA SS

dang thanks for the heads up. that sucks. i wonder what size die that would need? to have ready?

No die, needed, just spin the smooth end of the flare nut against the file a bit. The compression of the fitting tends to mushroom the end of the straight section a bit backing up to the flare on the tubing.

Damn I forgot about that. I don't think my new Wilwood lines are DOT. What do you think about a single layer wrap of electrical tape? It shouldn't significantly change the stiffness.

What about that high heat rubberized sleeve/tub people use for oil cooler lines near headers. That should be fairly resilient to road debris.

Thanks, I'll give it a shot!

Heat shrink is easy to apply before you install the lines. The shrink comes in different shrink ratios with 10:1 great for protecting lines of all types. I have some that expired for DOD use and I was able to buy it at a good price as surplus. Check around for USA made products as I have experienced some china stuff that failed (split) on new hardware and we made the vendor replace it will the proper spec heat shrink.

Most all ss hose kits are produced with a jacket on them today to keep out dust from getting into the weave. Clearly better than we had some 20yrs ago.

That said there is no such thing as a DOT approved hose. The US does not issue such thing and relies on self compliance to being DOT compliant. What makes one "compliant"? The hose must have a strain relief on the end at the fitting. Most of the time this is a black plastic slip over cover. It's really more cosmetic than functional...slide it back off, it doesn't do much. Also the hoses cannot use chassis adapter fittings- if you have a stubby adapter between the chassis end and the 3AN hose end (adapter with the clip holding it) then that's not a compliant hose.

Various manufacture do different things for different reasons....at the end of the day nobody inspects or verifies your hose kits to be approved by anyone but the manufacture itself..

*As a side note, most TCE spec hoses use a straight npt adapter to the Wilwood brand caliper and then a 45 or 90 AN3 hose end. We do this specifically to ensure our customers have the pipe thread tight and cannot break it off trying to "index" or "point" the fitting the direction they desire. The hose end is infinitely adjustable for this and can be quickly changed without potential damage to the caliper. And like the rest they are compliant, but not 'approved'.

That pipe thread bullsh*t is the biggest knock against Wilwood, in my opinion...
Especially when it needs to be 'clocked'.
Carroll Smith would be appalled.

I finally opened the box on the lines supplied by WW. As Todd mentioned, they are fully jacketed so no need for an additional sleeve.

well $hit, i got everything in the mail for my brake upgrade except the calipers.
well i just a message from ebay saying the seller refunded my order. obviously didnt like me stealing them for 15% off on black friday code on a "big" item

Hmmmm someone would be getting a call...

In the case of the AP Racing Radi-CAL, it's not just the material, it's the entire design shape and structure of the asymmetric caliper that adds stiffness. From our website:

Over the years, many different strategies have been employed to shrink the brake caliper footprint while maintaining adequate stiffness: More robust caliper bridge designs, two-piece calipers with steel through-bolts, exotic materials (i.e. Beryllium, MMC), forging rather than casting, monobloc design, etc. All of these innovations pushed calipers towards becoming lighter, smaller, and stiffer. However, until the advent of the Radi-CAL, the same basic rectangular, boxy shape remained the accepted standard.Is a rectangular box really the most appropriate and efficient shape for a brake caliper? AP Racing has now proven that it is not. As a brake caliper clamps brake pads against a spinning disc, a tremendous tangential friction force occurs between the pads and the spinning disc. In other words, the caliper is pulled strongly in the direction of the spinning disc, as represented by the downward pointing arrow on the right side in Figure 1 below.

The caliper resists that force via the spindle hard mounting points, depicted by the upward arrow on the left. The dynamic load placed on the caliper twists or pulls the caliper into a parallelogram shape. The dynamic force exerted on the calipers during a braking event is the key to the magic of the Radi-CAL design philosophy. Brake calipers of the past were designed to some extent in relative isolation from the forces that they were attempting to combat. They were designed to be the stiffest box possible while resting on a table, with much of the caliper mass residing at either end. The Radi-CAL is dramatically different because it was deliberately designed around the braking event forces that will be acting upon it. This is achieved by optimally distributing the body mass of the caliper on a diagonal, rather than at the two caliper ends. As such, the forces dynamically acting on the caliper are supported by the caliper mass, rather than what historically has been an empty box (see Figure 2 below). At the same time, this also allows for a significant reduction in overall mass, because all non-essential, non-load-bearing caliper body material is removed. So in the case of the Radi-CAL, it's not just about the material that is put into the caliper, it's about the material that is taken away!

The concept is along the lines of why an arch bridge is stronger than a beam bridge when all else is held equal. You can watch a vid and read more about it in the link below. It's not just marketing fluff. It's a major step forward in the history of brake caliper design:

That sucks, but this is fairly typical for many parts in the aftermarket, not just brakes. The number of bait-and-switch sellers is off the charts. Give us a call when you're tired of being jerked around and want a final solution, regardless of whether or not you're shooting for a championship. We'll be here!

I have black Willwood Calipers in stock that I can get you some sort of a deal on.
