Motive Products 1119 Large Round Style 1.5" to 4.5" Universal Adapter, Compatible Power Bleeder Attachments

Worked well to bleed the system very well. Even at 15psi the fluid moves a bit slow, but gets it done. The universal adapter I had to use with my older honda was a bit more difficult to get to seal well, but once I got it set, it was fine.Great product that makes it easy to bleed the brakes for less then the dealer would charge to bleed them once.

When first testing product found it would not hold pressure. Tested different things and found the clamp at the plate had caused a hole in the tubing. I took the clamp off, cut off the section of the hose with the hole and reattached the tubing and used a conventional hose clamp with success.

The unit shipped is square and does not match the size of the top of the master cylinder resevoir. It does not resemble the one in the picture. The square shape causes the wing nuts on one side to locate under the cowl lip and wiring along the firweall. It is difficult at best to access those wing nuts to really lock the unit down. I spent over an hour trying to tighten it down enough to make a tight seal, without success.The motive system is terrific. But, not for this application. For the time spent trying to make the seal and hold pressure, you might just as well do it old school and bleed the brakes with an assistant pumping the pedal or go with the mitivac system that pulls the fluid to the bleeder.

A little challenging to get leak free on my older 64 Dodge single reservoir master cylinder.It ultimately served its purpose.Dave

Works great! Candy believe it took me this long to buy one.

Great idea that works just OK. It’s painfully frustrating to get it to seal properly on the master cylinder. If you have a car with an odd size reservoir cap, it’s a good option

Need multiple adapters for different vehicles but it works

It will not go on a 1966 Mustang with non-power brakes.I tried to reach out to support multiple times, eventually I got a "you might need to cut it and make custom clamps."What would be easier would be parts so that I could put a hole in a replacement cap.This device did not have any directions on how to attach it and the chains, looped under the master were either loose or pulled the top off.I was never able to get a seal.I had no interest in cutting this up and building an entire solution out of something that just doesn't work.I went to the auto parts store, bought some hose and a replacement master cap. Plumbed that into the main pressure tank and was fine.Maybe this works if you have power brakes?Maybe it's for dual masters?No idea, but a complete waste of money for a 1966 with non-power brakes. It went into the trash.It was built well though. Just unusable.I want to note, that is just this specific adapter.In general, this product/brand/tool is a life saver when bleeding brakes.

Works great, nice size. Highly recommend this bleeder
