Yep, very slick and functional part. I used them when I swapped in Brembo calipers on my Mustang and it made the bleeding super easy.

Speedbleeders are great, a pressure bleeder from a garden sprayer is better but more work.

They always leak on me. The fluid takes the path of least resistance and in my experience, that path was out through the bleeder threads instead of going up against check valve spring pressure.

This. They won't prevent air from entering past the threads when you let the brake pedal return.

They can save a lot of time, but that needs to be noted. Leave them loose for a minute to gravity bleed before tightening, or press the brake pedal, hold it, tighten the bleeder, and then let it return to be sure no air gets back in.

I put them on all my cars, friends/family cars when I help service them. Makes brake bleeding or fluid refresh a cinch.

For my racecar they are especially handy. When doing a tyre change at the start or end of a track day i can bleed the last caliper in about 30 seconds given the wheel is already off. (pop ona hose, crack open 1/4 turn, pump pedal 4 or 5 times, close bleeder, remove hose). Top up reservoir now and again.

I have a pressure bleeder but prefer speed bleeders unless I'm doing a 100% fluid change and a clutch bleed: then it’s worth the extra setup and cleanup time versus effort spent with pumping the pedal and topping up fluid.

I had a truck that had really loose bleeder threads on one wheel. I tried a new screw but it was the casting. I was pedal bleeding into a fluid filled bottle and the air just leaked back in. I wrapped the screw with a little teflon tape and got the job done. When you close the bleeder the seal is at the bottom of the screw and the tape caused no problem.

They come with sealant already on the threads, but in my experience, the sealant washes off when the fluid goes passed the threads. I haven't tried Teflon tape. I think what I'm going to do next time is get a Motive bleeder.

I have them on all my vehicles but they do leak through the threads. I have the Astro Pneumatic one person bleeding kit w/check valve and same thing where air gets through the threads where I have to get my wife to press and hold on the brake pedal.

I have used them before, they leak. I still prefer gravity bleeding first and then coating the bleed ****** with grease and submerging a hose into a bottle of fluid and pushing the pedal. Works quite well, but you have to make an airtight seal imho.

When I did my old truck sealant coated screws hadn't been invented yet ha ha I got the Motive after readung a lot of reviews and it is that thread problem is why I don't like the vacuum method.

I had them many years ago. The thread leaks plus their eventual failing from what I assumed was Minnesota road salt made me go back to the 'wife presses on the pedal as I open and close the bleeder' method.

For cars, try a pneumatic brake bleeder. One person operation and superfast. No need to pump the pedal at all.

I've used them since the 1990's on 4 different trucks and have never had any leaking past the threads. If I had to remove one for any reason (changing out a caliper or wheel cylinder) I cleaned the threads and put some new sealant on them. You don't loosen them very much 1/4 turn or even less is enough in my experience.
