R1 and delink the brakes

[Squidley]

Just wanted to toss up a quick note to all the 1st genners that are thinking of delinking their front brakes and going with the R1/R6 front calipers. I just finished this mod on the '86 I currently own, and I used several different lines. The main line from the front brake master cylinder was off a 2nd gen. I sent this down to what I think was a Vmax splitter and then the R1 calipers I bought had the lines with it and I used them to the calipers.

 

The reason I am writing about this is I ran into a problem when I 1st put it together. I want to save you fellas some headaches should you want to try this. Let me start out saying that all banjo bolts are not the same. Also all brake line connectors are also not the same. The original equipment lines on the 1st gens have a groove inside the fitting and the banjo bolt has a full sized shank. The 2nd gen line does not have this groove in the line, nor does the R1 lines, so there has been an engineering change with this and the bolts are not interchangeable. What I ended up doing, was grinding a groove in my old bolt at the splitter, and also on the master cylinder bolt as I wanted to use the original ones to make sure they worked properly. I used the banjo bolts that came with the R1 calipers on them.

 

The pics below are of the differences in the bolts, and the mod plate I did to mount the splitter. I bled the brakes out tonight and have a good feel to it with newer lines.

Good tech info on the banjo bolts. References pics, but no pics here! Interested in the seeing the plate to mount the splitter.

 

I have a complete 01 Vmax front line set with the splitter. There is not a groove inside the line connectors. Looks like I need to track down the new style grooved banjo bolts.
