The weakest link in a stock bike's braking system is the rubber brake lines. They can bulge and split, and don't offer the consistent pressure and durability of a stainless steel braided line. Also, they look pretty weak.
Installation of aftermarket brake lines is pretty simple and doesn't require any special tools. Remember, you'll need to bleed the brakes after installing the new lines, so be sure to have a bottle of brake fluid ready.
1: Loosen and remove the lower banjo bolt from the caliper. Keep some paper towels handy and wrap them under the brake line to catch any leaking brake fluid.
2: Loosen and remove the upper banjo bolt from the master cylinder. Again, tuck paper towels under and around the area to catch leaking fluid.
3: We loosened the master cylinder so it would rotate a bit, making access to the banjo bolt easier.
4: The trickiest part of this job is releasing the snap rivet from the fender. It needs to be clamped from the inside, then pulled out. Yu might find it easier to simply remove the front fender entirely to attack them from the inside.
5: The brake lines from both calipers meet at a joint that's bolted to the lower triple tree. Remove this bolt and the brake lines will be free.
6: Assemble your new banjo bolt and brake line (the shorter line of the two) for installation with the provided copper crush washers. One washer goes between the caliper and banjo bolt, and one on top of the line and bolt. It's the same on both calipers.
7: Loosely install the brake line, but don't tighten fully.
8: Both brake lines meet at the master cylinder after being fed through the fender snap rivets, and use the extra long banjo bolt to attach to the master cylinder. The same procedure for crush washers applies here--one goes between each stacked component. Three total here.
9: Install the arrangement of both brake lines into the master cylinder, but again, leave loose until the lines are moved to allow full movement on the bars without hanging up or being constricted.
10: Here's your end result--new brake lines.
Add fluid and bleed accordingly. Not sure how to bleed your brakes? Check the tech section for instruction!
