Question on brake lines and RacingBrake BBK
Hey guys, Im finally getting around to installing my racingbrake BBK, and could use some pointers. I feel a bit silly asking such a simple question, but its either late and Im having a brain fart, or something is off. With the kit, I was provided 4 brake lines. (2 of each kind). One is a female end on both ends, and one is a female end, and the other end for a banjo bolts which would go to a caliper. Picture of lines:
The one with the 2 female ends also has a point in the center where it can be set into the holder on the stock front calipers. So, I had figured this line was to replace that stock front soft line, and then use the short hardline that went into the OEM caliper. (See picture):
This doesnt appear to be correct at all. But, just using the other lines provided will make them too short it seems to reach the caliper, at least going around the shock. Also, I have a set of stoptech rear lines, and the other 2 provided lines from racingbrake are the exact same length.. so are these lines for the rear? Any help would be appreciated. Again I apologize for the newbie-ish question, but it just doesnt make sense to me. Also, youd think with spending $3k on a brake kit, you would at least get a parts list or some sort of instruction.

I have the earlier version of the front BBK. It came with only one set, the short line with the banjo. It can not be routed like stock lines. It has to go behind the shock. Where it touches the shock, I wrapped the line with nylon spiral wrap to prevent metal to metal chaffing.
Your other line was meant to be used with the stock caliper but with the RB improved stock front rotors.

Thanks so much, that makes sense. Odd they would just include both sets of lines though.

Ok, so to bring this back up Ive finally had a bit of time to work on the car again. Got the front brakes all together, have 2 questions. One, I was supplied with 4 washers. From past searching, it seems alot of people had issues with their caliper being slightly offset, and these washers had been used to push the mounting bracket back slightly to center the rotor in the caliper. Now, I did not use these washers, and I took measurements and my rotor is perfectly centered. Was there a revised bracket, or am I missing something and need to use these washers?
Secondly, and more concerning is this brake line issue. I had run the line like was suggested above. It just seems.. well "half assed" for lack of better words. Does this look right to you? Im concerned with how it is bending the line near the caliper when the wheel is turned to the outside.

(1) There were two kits made.
The original had the short brake lines, and a clearance problem. One of the caliper bracket attaching points to the hub would rub against the brake disc hub. The spacers were to move the attaching bolts out because the stock bolts are also too long. You still had to grind a little metal off the wheel hub attaching point.
The redesigned brake kit supposedly fixed all of these problems.
With the brake correctly attached, rotate the disc to insure it does not rub.
Then when the install is complete, slowly drive the car in a very tight circle and listen for further rubbing. Grind off any offending areas.
(2) As long as the brake line does not get stretched, it should be good.

Lots of pics in my photo album:

Note that I have the non-standard fitment option which positions the rotors and caliper inboard for more wheel spoke clearance.

gracer7-rx7: Thanks, I will contact RB and ask about brake line options. Although, I purchased this kit new not all that long ago, so if this was an "issue", it seems odd to me that they wouldnt just change the supplied line.
cewrx7r1: Thanks for the reply. I secured the rotor down with a lugnut and spun it and saw no clearance issues. I will double check again to see how far the oem caliper bracket bolts protrude in towards the caliper. Its also not the line being stretched I worry, it is this 90* bend that occurs close to the rotor when the wheel is at full lock to the outside.:
GoodfellaFD3S: Thanks Rich, I was specifically looking for your album even before I made this original post, but couldnt find it. When I click on your profile, and then "albums".. only 2 show up. Perhaps Im just retarded And Thats cool they offer an option for lower disc wheels, fortunately there is massive amounts of clearance with my TM02s.. you can fit your whole hand between the caliper and the spoke:
