Ordering one of those right now.
Want to write up a quick and dirty tutorial pertaining to using that and the VN750? I'd love a "dummies" guide.
Here ya go, written from memory while sitting here at work. Let me know if anything needs clarification.
You'll want to start by connecting the vacuum pump to the provided lines and plastic tub.
Be sure to pay attention to the markings on the lid of the tub to connect it up correctly. One of the ports on the tub has a small hose attached pointing straight down on the inside. This port must connect to the caliper, the other port connected to the vacuum pump. If you connect it backwards, you will suck fluid into the pump (ask me how I know
Do not touch the brake lever during this process.
1. Connect the vacuum line to the bleeder screw of one of the calipers. (I did the right side first) . Do not open the bleeder screw yet.
2. Open up the master cylinder top and remove all of the old fluid. clean it out nice and pretty with a rag to remove any potential scum and debris.
3. Pour in some new fluid into the master cylinder
4. Pump up the vacuum pump to get some pressure If attached properly, it should maintain vacuum while the bleeder screw is still shut.
5. With a 10mm (??) wrench, crack open the bleeder screw. The old fluid will get sucked into the plastic tub.
6. Be sure to watch the fluid level in the master cylinder to be sure it doesn't get too low. At the same time, watch the gauge on the vacuum pump to be sure some level of vacuum is kept to continue to suck fluid out. You will likely need to give it a few pumps during the process.
7. At any point you need to add more fluid to the master cylinder, close the bleeder screw then add as needed. Repeat as needed until you are sure all of the old fluid is out of the line.
8. Switch to the other caliper and repeat.
9. Top of the fluid in the master cylinder and close it back up.
10. Pump the handle a few time to make sure you are getting good pressure, test the brakes as you would for a pre-ride inspection, and if all seems OK, take it for a careful test spin.
During this process, be sure to keep the vacuum pumps tub in as much of an upright position as possible. Do not let it get too full or you might suck fluid into the pump. Any time it gets full, close off the bleeder screw and empty it.
Depending on how old the brake fluid is in the bike, it will be a distinctively darker color then the new stuff, so it should be easy to tell when you start sucking the new stuff through the line.
