Never on any car I've put them on. It's quite a few now.

I had a earl speed bleeder strip in my Hilux's caliper. Scared me. I don't like the Earl design. I like the one with the internal ball & spring.

I've been thinking of using these, but I don't like that no fluid comes out. Sure, it's convenient and virtually mess-free, but I find it more convenient to get rid of fluid that has been water-saturated, to any degree.

I bought a Mityvac fluid evacuator for this kind of work. I like that it has other uses as well, like sucking the gas out of my snowblower tank each spring.

I never had confidence in the solo type bleeders. I've always used A Motive Products Power Bleeder.

Better to use a pump like Lou and Mike posted.
Speed bleeders are spring loaded. When you unscrew them a tiny bit, they allow for air to exit without the exit of fluid. This way you deal without the mess of bleeding the brakes.
In my opinion, I would want some fluid to exit the system, as brake fluid absorbs water over time, especially dot4. No hurt in flushing out some fluid for new fluid

My brake bleeding catch bottle disagrees with your analysis. There's no such thing as a gas only bleeder for brakes. They all open and allow fluid out.

Anyone using pressure to bleed brakes is dissolving air into the brake fluid unless there is an air/fluid separation piston in the system. All fluid and all solids contain gas molecules. Compressing fluids or solids only adds more gas to the system.

I used to think vacuum was great conceptually for bleeding brakes, but unfortunately there are too many seals far too willing to allow air into the system from atmospheric pressure when the seals fail to seal under vacuum. They weren't designed for vacuum, only for pressure.

I still prefer the bottled vacuum-system

I agree. I have used power bleeders and vacuums to flush and bleed brakes and I keep going back to the trusty old two person method flush (well one person with speed bleeders) and then I finish by letting each caliper gravity bleed. From my experience that is hands down the best pedal I've been able to achieve. It's also very simple and the most inexpensive way

^^^^I just did mine last week, and as Lance's first post indicated, the front and rear use the same part number. They worked beautifully for me. And again, I want to thank Lance for his great suggestion.

It's too bad Earl's site and all the reseller's sites are so far behind the times in updating their application charts. There's a lot of sales to be gained, IMHO, if their application charts were up to date.

Oh, I see by your profile that you are not an ISF owner. The ISX50 does indeed use different Earl's Solo Bleeders front and rear.

This thread seems to have your answer:

Hey man thanks for replying to my question. I'm installing ISF brake on my is350. So for some reason the rear bleeder screw has a different thread size then the front. Don't know why but thats the case.
