rook and if you look on ebay they have speed bleeders on there 3 for $20 once they are opened they only let air and fluid out no air gets sucked back in truly a 1 man bleeding job

+1 you will never need braided lines on your street bike the brakes on the 14 are already very good.

true the brakes on the 14 are very good but just like any other bike with oem lines the rubber lines get soft and start expanding with braided lines that dosent happen.

I don't think anyone mentioned that the Dot5 fluid is silicone based. Very high boiling point and doesn't attract moisture. Also won't hurt paint/plastics if you spill some. I've used it for 30 years in my '79 GS1000 with no problems. Seems too good to be true. However, last year a front caliper mysteriously gave me trouble and I never could figure out what went wrong. Many others claim the silicone swells rubber and maybe the piston seal caused my locking calipers. I don't know.
I decided to stop using it and changed the front on the 1000 to Dot 5.1 which is glycol based but has the highest boiling point of glycol based fluids (522 degrees). I still have silicone/Dot5 in the rear and will unless trouble comes up. One thing for sure, if you ever go with silicone and then want to go back to glycol based you have to CLEAN the parts like crazy because the silicone is tenacious stuff.
I like that Mity-Vac tool and will probably buy it. My 1000 has Speedbleeders on it and they work pretty good. But I did have one start leaking (that bad caliper) and I couldn't stop it from leaking. Probably my fault from over-tightening over time. Once I had the caliper taken apart you could see a slight impression in the metal from too much torque most likely. You gotta watch tightening small parts. You always want to tweak it juuust a bit more to be sure. Something like 4ft/lb is all these things need I think. Even though the Speedebleeders work well I think that Mity-Vac sounds like a good idea, especially when you figure it should last a long time and you'll get your moneys worth.
What else is cool about a good tool like that is that it ENCOURAGES you to do the job at intervals the service should be done. So it might save you from other problems/costs related to putting off the work.
As for what fluid to use I'm sticking with the Dot 4 per the factory manual. No problem finding it around here.

It is more the subtle things that are missed.

1. Washers are set in a direction having more surface contact to one side so you take advantage of that move.
2. If you push fluid up from the bottom, fill the master, your only bleed is the master as if you started from the master and the bubble rise to the top anyway. It was a waste to nipple bleed the lowers if you want to salvage that taper in the caliper to seal, you leave it alone as much as possible. Open and closing wrinkles that machined groove. There is a one time open/close method and you are watching too many screw wrinkles to the caliper-to-taper moves.
3. Now Dave says to have air in the master? You want no air to act the water droplets on the roof of the diaphragm think. You want that master filled so the other side of the 14.7 pissing contest is on the other side. There is no air or moisture to mix with the oil. You now have zip air but the oil displacing the one side. You have the air side is that diaphragm with the air now. Now you see it?
4. Where was the brake pad wear as opposed to the overfill of the master now. Someone forgets that extra oil, goes to change a front tire, pushes the caliper pistons in and that diaphragm collapses and there goes the oil out the master onto your paint. YOu are working at the bottom looking down... LOOK UP!
5. LOOK OUT! Like blue has a disagreement, I too disagree with quite a few moves or carbon buildup theories like ducks are lined up and shot out of the water watch out on the net or someone is gonna get it right > For your decision making, [not mine]. Figure out the steps or get stepped ON... "The DonkeyKongizzz ON! Dave Moss!" Dis Donkey Ho TEA is going to hose your moonsteer and where is BROCK? I'm not done! I have weirdwaysingworld questioning their tech... Page 16 Dec. 2010. Call it coincidence I mention 5 air bag bikes and the tech mentions ignition retard? Is it not the air retard, hello? Who came first, the retard chicken or the air gate quack'inn me up with air gates is that slowing fact of the egg walking across the street is the theory.
6. Variables like 3V and 3wV = 6 fun due mental cases do I bring up is now mention Ivan and that hatrick. 4 are all lined up like ducks yes or no?
7. Cum 11 you stand in front of that fish market with that theory; are the dead fish I pick up that wash up ship to shore here fishy-fishy come get, SmokedaFeeish behind the smoke house of cards! PAz says PAY UP!
8. Ball is place me or you behind the 8-Ball and now stick that rug right up your clue stick is take the shot!
9. Out of 10 times I yes/no the tech is a no show as show both sides and now choose to lose make that move > 1 to
10. = No one comes to the table... And that yes/no kink in hubbish is the rubbish in pure speak they know the difference give me that shit!

I spent lunch with my old race buddy. We are swapping stories. He tells me about one guy (a story in itself) he had in his pit. The hot brake oil was silicone dot5. I ran that shit back then. But getting back to that brake change, his pit guy swaps oils from base dot4, and they mixed. Now the story heads to cherry read discs and it's locking the caliper rubber all up. He said there was the white (obviously) crystal all inside.

You are going to watch the crystal ball. It's swaying left to right now cough. We clear on the clear we do not mix mix is mix at all? Oil is oil but to mess with the mix is accelerate the crystal'ing my brake drag, say, have you seen my glow plug on wheels?
