Thanks for offering your old stock lines, Jim, but I'm guessing the ones I have are probably identical to yours.
. I have been studying the threads and videos related to IABS brake bleeding. I'm feeling a little less intimidated, but I think I may pick up a funnel and a bleed bag to make the job a little easier. I'll also pick up a couple 7mm wrenches for fabricating a special wrench.
The Spieglers should arrive mid-next week.
That post was a bit tongue-in-cheek - no offense intended. I was going to quote Dirty Harry and ask "Are you feeling lucky, Punk?" but refrained.
Glad you are tackling replacement. As mentioned, lots of good write ups and videos on bleeding iABS brakes. For our generation iABS, you don't need the funnel like the newer version. Also, I am definitely NOT a fan of reverse bleeding after doing it once - it just makes a big mess, can push contaminates from the calipers to the ABS module and you still need to forward bleed the control circuits afterwards in any case.
I don't know how to link other posts, but some pointers I learned doing this:
1. Before removing the handlebar reservoir cover, turn handlebars all the way to the left. Although not absolutely required for bleeding, I remove the 3 switch assembly screws, loosen the brake assembly clamp and rotate it so the reservoir is as level as possible. Replacing the hose requires this anyway - just leave it loose until after you bleed. Put a quarter over the hole in the sump so fluid doesn't squirt out while you are pumping the lever.
2. To access the bleeders on the ABS module, get two 7 mm combination wrenches (Home Depot has them for $1.99 each) and bend the box end of one 90 degrees for R2 & F2 ports. You'll have to remove the "FFA" clamp bolt for R2 and remove the battery for F2. Bleed sequentially F1, F2, F3, R1, R2, R3 several times. See picture identifying the ports (courtesy of John Sailor).
3. For bleeding the wheel circuits, turn the key to on (do not start) and use the servo pumps to push fluid from the reservoir(s) to the calipers. Be careful to not drain the reservoir! A trick I learned here is to replace the two overflow hoses from the caps with hoses submerged into a can of clean DOT 4 brake fluid to replenish the fluid level as you pump. See picture. Many here use Valvoline Synthetic DOT 3-4. I went through almost a whole large can to thoroughly bleed after Speigler brake hose install.
That reminds me it's been a year since I did this - time to get back into the garage to flush the brakes!
