I see a lot of older threads recommending either Speed Bleeders or Motive Pressure Bleeder, is there really advantage to one versus the other? To be honest I rather do the Speed Bleeders as I live in a Condo with limited space so just one less thing to find a spot for but if there is some sort of advantage to the Motive unit other than just ease then I will find some closet space for it. Also do the front calipers have two bleeders each, if so do those require 2 speed bleeders for a total of 4 for the front and 2 for the rear?
Motive Pressure Bleeder or Speed Bleeders?

I just purchased a motive... Fill it with race blue pump it to about 12lbs start rear passenger and work around... Keep an eye on pressure thru out the bleed... Ys the fronts have 2 bleeders start with inboard side and move out outboard.
It's a great process and supper easy... And don't take up much room it's like 16" tall.

I've been vacuum bleeding brakes for years. Many Vipers. No fluid under pressure if something goes wrong.

Dave666 I bought the Mightyvac that you posted about way back when and I love it, use it all the time and it's more than paid for itself. The only thing I don't have 100% faith in it is bleeding brakes. Since it's sucking air through the system you always get bubbles with it through the bleeder so it's hard to be sure you've gotten all the air out of the lines. It's strange I seem to do okay with newer cars (Vipers) but I was doing a buddy's '69 Vette and we couldn't get the air out till we went old school by pushing the peddle. Do you have any tips? Sorry for the hijack KDR83.
What's the advantage of pressure versus vacuum bleeder or vice versa? I see the worry of not being sure if there are any bubbles in the system come up a lot with a vacuum bleeder?
And see Dave, not all my posts are about making my car pretty

I have used both and my opinion is that the Motive gets more air bubbles out because it is constant pressure when you break the ****** at the caliper so it pushes out air in high spots in the lines. The other method stops and starts many times throughout the bleed and the bubbles just move back up to the high spots in between squeezes. I always am paranoid that it will squirt all over the place some day so I take absurd precautions with it in a bucket and covers over it. Takes the worry away.

I have both and prefer the speed bleeders.
I guess it's just a personal thing, but I just feel better pushing the brakes to get all of the air out. With the Motive, I just didn't "trust" that I got all of the air out. Plus, I didn't feel like the Motive was working right unless it had more pressure running to it that I felt comfortable putting on the system.

On other cars, I've never had any luck with any type of vaccuum bleeder. I've always had to do it the old fashioned way (the pedal). I did try a motive power bleeder once and it was amazing. I still haven't bought one but really need to. Connect, pump it up, and open the caliper valve and it all flows out without any additional effort, and the power bleeder itself also refills the reservoir so you don't run dry. It's a great invention.

Does anyone know what the proper cap part # is for a Gen3/4 car?
I use the Motive but don't fill it (just use for pressure)
My steps are:
**** out old fluid with turkey baster,
Fill to top with new,
Screw Motive on(empty) and pump up,
Open Bleeder screw on caliper and tap on caliper with mallet to assist in freeing air bubbles.
As i see the reservoir is getting low i shut the bleeder valve.
Slightly unscrew top of motive tank to relieve pressure, Then remove cap & Top off fluid reservoir,
and on to the next corner/caliper.

I have used the Motive system numerous times to bleed my Gen II and it works very well and is simple. No running back and forth to pump the pedal. Ford 3 prong cap works great. Shop manual recommends pressure bleeding. I have heard that bleeding by pumping the pedal can result in over travel of the master cylinder piston and possible damage to seals. Not sure if this is true. Have not had that problem with bleeding other cars.

I am not a fan of the speedbleeders. Numerous reasons.
I've been pulling the fluid out for many years and it as never failed me. The vacuum comes in handy for other stuff too, like the power steering, differential, clutch or any other case where you wanna get that last drop out.
And why is vacuum spelled with two u's? It should be spelled with two c's, one u and an e. Like vaccume.

For the same reason your name is spelled with a C and a K. Haha
