HF: Pneumatic Brake Fluid Bleeder

[DodgeRamz2007]

I know a lot of people do not like Harbor Freight tools, and I do agree there are a lot of items I wouldn't buy either; however, I did pick up this pneumatic brake fluid bleeder http://www.harborfreight.com/brake-fluid-bleeder-92924.html and it worked great.

I used it to suck out the brake fluid reservoir. The fill bottle made sure the fluid level remained where it should be. I bleed the brakes and it worked great. It recommends 90 psi, but I run it at 40 psi and it worked nicely. Great tool for the price. I am going to use it next to change my rear diff fluid so I don't have to take th cover off.

Just wanted to provide some information about this nice little tool.

90 psi? My motive does it at less than 5 psi.

Does it suck or blow?

It say 90psi, I sucked out the fluid at 20 psi/bleed brakes at 40psi...could have done it at a lower psi. It just sucks fluid.

This is a vacuum brake bleeder. It just happens to use air pressure to create the vacuum. Its not like the ones that actually push brake fluid through the system under pressure.

That is correct sir!

Pressure bleeding is probably better, but I've used a hand-pumped vacuum bleeder for at least 10 years. I have had some rebuilt calipers on my Camaro with worn bleed screw threads that the Mityvac couldn't pull fluid through.

Got it. Dont remember all the details, but I bought a pressure bleeder instead of a vac one when I got my motive for some pretty compelling reasons. They escape me though...

A side topic, if one uses teflon tape on the threads of the bleeder screw to prevent air going past when bleeding, do you need to remove the tape when done bleeding?

That is interesting. I have never heard of someone using teflon tape on bleeder screws. Not sure what leaving them on would do.

Since no manual tells me to, I also never use teflon tape there.

However, it might be an advantage by keeping water away from the threads, which often causes rust and makes the bolt break off inside the caliper.

One could remove the teflon tape after bleeding.

IMHO no need to remove the tape as long as none got under the seat area of the bleed screw. As stated might help keep some of the nasty stuff out.

Living in the rust belt I bleed my brakes once a year. It exercises the bleeder screw and no worry on breakage. Lube my caliper pins twice a year autumn and spring.
