One Man Brake Bleeding
 
Ok, so this question is not for my Porsche, because I have the Motive bleeder obviously. I have a few other Hondas, and the reviews about the Motive universal adapter are not so great that I haven't bought one.

So here's is how I have been bleeding my brakes by myself: I top off the reservoir, attach a hose to the bleeder valve, stick the other end into a container, slightly wrench open the bleeder valve, go pump the pedal several times, make sure fluid has been coming out, then tighten the bleeder valve, top off the reservoir, and move on to the next one.

Please tell me if there's anything wrong with this method, or anyway air can get back into the system?

Yes, use the correct adaptor for the vehicle (Motive makes a lot), and put the fluid in the Motive unit like you are supposed to do. It only takes about 5 min. to clean out the Motive unit after you use it, and you will save a lot more time than that by not having to run around the car.

You need to be Motivated to do this by yourself.

Since I really have no friends, this was my only real option.

i put speed bleeders on my calipers.

+1 on speed breeders. Then your friendless process works.

You know, I've been accused of speed breeding.....:(

One word: Mityvac.

You can't open the bleed nipple and then pump the brake pedal several times. Each time the pedal comes back up, it will suck air back into the bleed nipple. You should press and hold down the brake pedal, open the nipple, allow the fluid (and air bubbles) to come out, then close the nipple before you release the brake pedal. Then repeat until the new brake fluid reaches the bleed nipple. That's why it's a 2-person job, or 1-person, easy peasy, with a Mityvac :).
Don't forget to keep the brake fluid reservoir topped up, or you will suck air into the top of the system.

I prefer the Motive with the European adapter. Super simple, no chance of air to get in.

I think Motive only has a universal adapter for Hondas, which is the one with the chain around the reservoir to clamp it down. People on Honda forums say that adapter is very flimsy and hard to set up for air tightness.

I have that adapter for my Toyotas and it is very hard to get an airtight seal, a lot of fiddling is required... I am back to using the two man method when bleeding those. But for the Boxster and my son's Miata (whose clutch cylinder is the same as the boxster brake cap) which have the screw on adapters, the tool is the way to go.

I have the hand pump Mityvac, and it sucks a lot of air through the bleeder valve thread, so I can't tell if my system is free of air when I use it :(

Always use the specialized tool for this procedure.

I think this method is probably ok. Potential problem is if air leaks in around the bleed screw threads. If you have the hose set up so fluid siphons into the catch can while you are not pushing the pedal it should be ok.

Another option is to build your own motive adapter for the Honda. Buy a replacement cap and attach a fitting to it for the motive. Drill/tap the hole if there is enough thickness, and JB weld. I did this for my jeep before an adapter was available for it.

There are two different size adaptors for the Honda/Acura line: Honda uses two size reservoirs. One reservoir is approximately 2.5" in diameter - that one uses the 1101 cap which comes with kit 0101. The other reservoir is about 3" in diameter. It uses cap 1119 which comes with kit 0119. You can use the 0119 on both size reservoirs, however the 0101 will only work on the smaller Reservoirs.

While both are "universal" style adaptors, they both work well, we use them regularly.

Hancock,

Why don't you put some teflon tape on the bleeder treads..? This will help to keep you from sucking vacuum through the treads.

You're joking right? You shouldn't say things like that. People who don't know better might actually do it.

get a piece of air tubing like for an airline for an aquarium with a diameter that will fit over the bleeder valve. get a small clean jar with a cap. punch a hole in the cap so the airline fits into the hole and reaches the bottom of the jar. half fill the jar with fresh clean brake fluid. prop the jar so it stays upright and wont fall over you can use wire or a large rubber band. open the valve and leave it open. make sure the brake reservoir is full. now pump on your brake pedal. the air bubbles will be forced out and when the brake pedal is released it will suck in new fluid from the jar.
