I have used a Motive bleeder before and it works great once you have it set up. Put it up to around 10-12PSI iirc on the reservoir and then just open/close the bleeder valves in sequence until you see fresh fluid.

The only catch is that depending upon your application, pressurizing the reservoir may be a royal pain. For example, OEM Honda twist-lock lids just don't hold pressure and I haven't found any aftermarket adapters that fit well. Some are ridiculously tight to the point that they will break the plastic reservoir while others instruct you to clamp a flat plate down hard on top of reservoir lip using a chain (lol).

I ended up epoxying the upper half of a threaded Porsche 356 reservoir onto the lower half of the stock Honda reservoir on my 85 civic. The epoxy joint held fine but some pressure ended up leaking out between the Porsche threads and the motive adapter cap anyway, go figure. Maybe a lower pressure would have helped but I was already using below the recommended pressure (15psi), so YMMV. Just be prepared to clean up drips and leaks.

check out the CTA 7030 and 7043 adapter for Honda.

Wrong size for most applications.

I did buy a CTA 7032 for my Prelude but it is so insanely tight to get on/off that that I only test fit it once because I was afraid the reservoir or locking tabs would snap. Spec listed on the website is 74mm but the plastic on the adapter measures 74.8mm and the o-ring brings it up to over 76mm.

Ask 20 people and you'll get 25 answers. Here's mine. Get a Vacula vacuum bleeder (or the Chinesium clones available everywhere now). I've had mine for 25 years. By far one of the best tools I've ever bought. One pass at each of the wheels and you're done. You don't even need to bench bleed the M/C, it will pull the air out.

Long clear hose looped over a ladder, pump away.

Gravity will keep the line full of brake fluid, so no air will get in, and any air in the system will rise to the top where the line loops over the ladder.

Obviously a catch bottle at the end of the line. I use an old brake fluid bottle, two holes in the cap, one just big enough for an interference fit for the line, the other hole acts as a breather.

There is no wrong answer, we all have our favorites. In my case, and I bleed/flush a lot of brakes, I have motive pressure bleeders with all the adapters and 2-3 vacuum setups which all work fine, but 99/100 times, I use my bleeder bottle. I a not even sure if my current one(s) all have the check valve, it doesn't matter if the pickup is under fluid in the bottle.

I take out the bleeder, wrap the threads with teflon tape and reinstall it. Then I use one of these:

The teflon tape prevents air from going back into the bleeder past the threads.

Has been working great so far.

For home use this is cost effective and reliable, I have two 200ml Syringes. I have one for sucking fluid out of brake calipers and reservoirs (the dirty version) and another for back bleeding hydraulic clutches by "injecting" fresh fluid in to the slave cylinder (the clean version). They cost around £3 each!!!!

Silicone grease works pretty good for sealing threads if you get bored using PTFE tape 🙂

Motive with various adaptors for the cars/trucks. Works great, cheap and easy. Should of bought one way before I did!

This is what I use: https://www.amazon.com/dp/B00F9XHVKA/?tag=atomicindus08-20

It was expensive for what it is, but once you own it, you never think about it again and it was well worth the money.

I also take out the bleeders and lather them in anti sieze. Learned on my last brake job that the aluminum calipers GM uses are a PITA if you don't replace the fluid when its due.

I started with mity vac and it was terrible. I then tried vacuum bleeders but they always pull air from the threads so you don't really know buy looking at the tubing if all the air is out, you just have to assume.

I tried a friends motive and it was pretty good but if you put brake fluid in the resivor its a mess when your done and absorbs water if you don't put it back in the bottle until next time. If you just use it as a pump for air it works well but why pump when you have an air compressor.

I ended up buying a power probe cap for my vehicles and it has all the advantages of a motive bleeder without the manual pumping. Do have to stop, depressurize and add fluid if you do it this way typically after your done with the rear axle but its clean and easy.

Thats unfortunate. I had emailed CTA for my Honda applications, and they pointed me to the 7030. It fits well, works much better for me than Motive’s “universal” adapter plate and J hooks. Power probe also has a Honda cap, you might check with them.

I second this method.
An enthusastic third. I'm a DIYer, and usually have not had a second person to pump the pedal. I had the little bottles with brake fluid, but I hated not being able to see what was happening as I pumped. I then graduated to a vacuum pump, and that worked better, but it was a lot of pumping. Next, I tried the air-operated vacuum version, and that was a huge improvement. But then I learned about the Motive, and bought one, and it's by far the best method I've ever used. Pump it up and the fluid & air just spits out like gangbusters. It's very easy to get a good, firm pedal with the Motive.

Either pressure or vacuum both work good. Each has its place. I chose vacuum with the mity vac. Not the fluid suckers but the dedicated brake bleeder vacuum they sell that runs on air and has an auto fill jug for the master. It's pretty expensive but when you work by yourself most of the time it comes in handy. There has been once that I couldn't get it to **** fluid from one caliper and had to have a helper two man bleed to free it up. Not sure if there was something in line or what. But after a few pumps of pedal the vacuum worked great. So not sure if a motive style pressure bleeder would have solved that or not. But overall I've been very happy with they mity vac for the last 15 or so years I've had it.

I use a motive but really should buy one of those allstar bottles to reduce the mess.

Yep, I always use silicone grease it's way faster and you can just wash off the excess with brake cleaner after you tighten the bleed screws.

I used an expensive fancy pressure bleeder at the dealership, but the adaptors were always missing/broken or it was just a filthy mess after the last guy used it.

I use 4mm silicone tube with the syringes and it's clean quick and above all very cheap, it's very rare I work on brakes nowadays but I back bleed a lot of clutches after they run the reservoir too low and they can't get a pedal.

I used an old metal oil squirt can for years, but the brake fluid melted the paint so switched to plastic syringes, the seals last quite well considering, I just buy new ones from ebay when they start getting a bit grotty.

I personally wouldn't spend a lot of my own money on any tool that is in constant contact with corrosive brake fluid (sooner or later you will have to fix it).

Slow, BUT IT DOES WORK !

Make sure the reservoir is full and stays full ! Get an old plastic quart bottle with a screw on cap and about 3' of clear vinyl. Also find a spring clamp that will guarantee the hose stays attached to the bleeder screw. Drill a hole in the cap slightly smaller than the OD of the hose. You want a tight fit. Place about 1/2" of brake fluid in the bottom of the bottle. Feed the hose in to the bottle until it is BELOW the level of the fluid. Crack the bleeder and walk away for at least 5 minutes. Check often because this will drain the reservoir !

Make sure the bottle stays upright and the hose is always below the level of the fluid in the bottle.

I do the same and work on other areas of the car while draining the calipers of old fluid (Track car) Make sure to keep an eye on that master. I have a suction gizmo but found it do be a PITA. It sits in a box somewhere.

I had a motive pump and a mityvac and I just gravity bleed. Really nice to lift the car and use a few feet of clear hose.
I'm not sure if Motive fixed this or not, but after a few years, all the hoses crumbled from being exposed to brake fluid. Luckily I didn't find out by spraying the car with brake fluid.

The only problem with this idea is that Power Probe doesn't make or sell these anymore. Great idea though.

I have been using the Mityvac MV6835 for years. Hooks up to your air compressor and no adapters needed for different cars. Works very well but you have to ignore the bubbles you see in the tubing as it does pull air from the connection to the bleeder and perhaps through the bleeder threads. You can effortlessly move a lot of fluid with one of these....
