Props to a new tool - AGM Pressure Bleeder

[TrackRat350]

I don't typically make recommendations for tools, but I used one this weekend that is worthy of sharing with you all. I flushed/bled the brakes on my 350 using a AGM-products pressure bleeder and it was a great experience. I have also used a Motiv which you have to hand pump and in my case - work around the leaking fittings. The AGM uses shop air and has a built in pressure relief valve. It also has quick disconnects, a quality catch bottle and a big syringe to clear the old fluid from the reservoir. This is just my .02 cents on this time saver. Good job AGM. https://agm-products.com/collections/tools/products/brake-pressure-bleeder

Looks very similar to the unit I have - a Sealy VS820 - but with shop air instead of a pump. I gave up on pumps years ago and I use shop air through a pressure reducing valve into a Schrader valve on the screw-on fill cap. If the AGM uses the same body and fittings as the Sealy, it's a great unit.

Of course, there's always a catch, and in this case, I only use the Sealy for the cars in the family fleet that aren't the GT350. For it, I installed Stahlbus bleed screws.

I haven't looked into it on this mustang yet, but on my old ST you could use forscan to turn on the ABS pump and easily bleed all of the breaks. You'd top off the reservoir, hit the button and open the bleeder, then it would purge out all the fluid. Repeat 4 times.

The pressure bleeder works but if the mustang has the auto-bleed option its way better and cheaper

I know I’m resurrecting an old thread, but which master cylinder adapter did you use for the AGM pressure bleeder? I just went to try mine and the 1495 adapter they recommend for Mustangs does not fit

I've oogled those things also. Very trick. Curious, why that route for the 350 only? You prefer them over the Sealy?

The Stahlbus bleeders have an interesting design. You can back the inner screw out two full turns and brake fluid will flow just like a loosened regular bleed screw. Well, with the exception that there's no seepage past the threads because there's an o-ring seal preventing it.

But, if you only back it out 1/2 a turn, the bleeder becomes a pressure bleed work-alike. It takes a surprising amount of force on the brake pedal to push fluid out past the spring-loaded ball valve in 1/2 turn mode, and that means that any air bubbles in the system will get squashed and knocked loose and come out through the valve with the fluid.

The Sealy is a great unit - but if I want to be absolutely positive there's no air in the brakes, the Stahbus is my go-to.

That sounds pretty cool, and a pretty darn solid endorsement too.

There's a new trick I tried on one wheel last year that I'm going to use again this year on all four. I backed out both inner and outer bleeders to 1/2 turn and pumped the pedal. I was able to bleed inner and outer caliper halves at the same time. I checked with my brake fluid water gauge to make sure both inner and outer were pushing out new fluid (0% water), and it worked great.

An interesting side-note - I just checked my GT350 Maintenance Manual (the CD) and it says to use a pressure bleeder that puts 50 to 60 PSI onto the braking system. It's the same design as a Sealy, and at 60 PSI, all air bubbles in the system will definitely be gone. You just can't do it with the plastic aftermarket Sealy-type units because they'll explode at that pressure.

I use the Stahlbus on my car as well after @JAJ 's recommendation and can attest to their high quality. When I bought new ones for my AP calipers and went to install them, I realized they were a couple mm to short. I had bought them months ago, so I thought I was hosed. Reached out to them and they exchanged them at no charge even though I had opened them, installed one and bought them 6 months earlier.

A+ company

BUMP - TTT

Me too. Wife just bought me the AGM bleeder and need to know what adapter to use.

Since the adapter for my Motive is for " From Alfa Romeo and Audi to Ford, Porsche and VW" (it's red) looks like the AGM 1501 should work (?) It's a screw on:

Anyone? Bueller?

I ended up reaching out to AGM and Navid there was super helpful. It is the 1501.

Yes, that is a great tool. I usually rebleed the brake system BEFORE replacing pads and rotors.

 

[RedYeti]

When replacing brake components, bleeding works incredibly well using ForSCAN’s ABS module bleed while supplying it with fluid using the AGM pressure bleeder

Great. Thanks.
