Wow, this is a relatively cheap mod that yields a substantially greater stopping power which is key now that I have 33's and may move up to 34's. Great right up and job well done!!
 
I have not heard back from Crown Performance yet. Anyone know if it is possible to go from the frame/body connection and directly to the caliper and bypass the bracket connection?
 
Talked to John at Crown Performance. He said there are a couple people from the mud forum who have ordered and installed brake lines; Frame/body to Caliper, bypassing the bracket connection and eliminating the hard line.
A customer installed 20" line who had 3.5-4" of lift, but claimed that the 20" is slightly longer than needed. I only have 2.5-3" of lift, so I will plan on ordering a 18" line and see where I land.

18" brake line will work. I was first one and have 20" long lines which are +4" over stock. I don't have tundra brake caliper conversion but I do have tundra control arms/CV axles. Tundra caliper conversion has a hard line.
 
I would clarify w/ John at CP that this is NOT the same order. A few of us have since ordered extended SS lines from them after @Atwalz but really just a direct replacement to the OEM ones, but SS and a bit longer. Sounds like you need a Tundra version, but yes I assume as long as you get the ends correct CP can make whatever you need them to make. @bjowett?

Right, Tundra caliper conversion has a hard line from caliper to bracket, and then another from bracket to frame/body. Talking to John at CP, he mentioned it can be a single SS line going from Tundra caliper (regular flare connection) to the frame/body connection (female) and in the middle would be bolted onto where the bracket connection would be. This new SS line would eliminate this bracket connection. But does this mean, it would be much longer than 18-20"?

Be aware, the tundra caliper does not use a banjo bolt. Be very specific about ordering a tundra frame to caliper line. Sounds like 18 to 20 inch will work.
 
Ok, thanks for the clarification @TexAZ. I'll ask John to refer to the existing Tundra SS brake lines and just extend the size to ~18".
 
These are the type of connections that CP (crownperformance.com) can have on the SS line ends. I believe I would need the regular flare connection for the caliper and the 1086 female for the frame connection.

I'm trying other options, Crown Performance does not have Stainless Steel fittings.

Spiegler does.
Standard-Lines

@Atwalz , @Mogwai , @TexAZ , @bjowett , anyone can snap pics of the ends of the brake lines you removed off the URJ200 I can send to Spiegler so I dont end up ordering the wrong fittings? Or please chime in.
And I also believe both the external threaded (Tundra caliper 47750-0C030, 47730-0C030) fitting and the frame side internal threaded connection are M10x1.00mm, please correct if I'm wrong.

This 90deg swivel connection may work well for the Tundra caliper.

Frame side connection
Unsure which I need here, as I believe there has to be a clip groove to be accounted for, and none of them are swiveled fittings.

option 1.

Option 6.
2 more options, 810 and 830, but they are both AL.
 
Considerations.

Connection at the hardline:

1. OD of the female fitting has to be small enough to fit through the bracket. Anyone have this?
14.5mm, thanks @Atwalz. Since CP lines are actually 15mm OD, one can get 15mm OD female fitted brake lines.
2. Does the female fitting have a concave or convex bottom?
Concave
3. How thick is the bracket? Need to make sure there will be enough of a groove sticking through to get the retaining clip on.

715 and 716 look like good contenders for this particular connection. Will confirm with measurements, OD of 7.8mm (715) and 10mm (716).


Connection in the middle:

4. Does the brake line go through a mounting hole or is it attached only by the tab locator? If it is routed through a hole we have to make sure the fitting at the caliper will be able to fit through this.

I believe it is mounted by tab, can someone confirm?

5. What size bolt is used to mount the line? I want to make sure it will fit through our tab locator.

8mm I believe?



Connection at the caliper:

6. 90 degree male M10x1.00 fitting.

419 fitting will be the one to go with.

Here are CP line +4" longer than stock.

Measurements of OE lines are in my build thread.
 
I threw away my OE lines.
 
Thanks @Atwalz, on that second last pic, CP line on LC, what is the wrench size on the CP line? Trying to determine what the OD should be to get through the hole.

Goodridge lines are 15mm OD.
