🔧 Dorman 788-522 Brake Line Adapter-Bubble Flare-M10-1.0 x 3/16 In. x M12-1.0: Reliable Solution for Brake Line Connection Review

The description tells you that you have a bubble flare on the 12mm plug end but no reverse flare on the socket side. Maybe include a picture of both ends or describe the product in full.

The male end is a bubble flare (as stated in the product description) and the female end is a reverse flare (which is not stated anywhere). that would be good to know. I was lucky enough to have a drill press with a vise and a brand new drill bit, I couldn't imagine hand drilling it. It would be great to include photos of both mating surfaces to show the type of mating and/or reference both surfaces in the description. I'm only giving 2 stars because I was able to pierce it to get it working…

As another reviewer mentioned the 10mm socket is not machined for a bladder expansion caliper. It needs to be modified (with a drill) to properly seal the Bubble Flare port. The problem is that because the part is brass, it has a "brittle" finish and it's difficult to get a good enough finish for a hydraulic seal with a hand drill and vise in your garage. just know Otherwise, it seems to work well as an adapter. Two stars for an important Mi representation of the play!

Large male end is correct but inner M10 end is reverse flared. I had to cut a brand new end of the line and extend it back to the correct inverted flare to make it work. I bought this because I called Dorman and they even told me on the phone it would burst a bubble for both parties! I had to have this ending so I made it work, but shame on you DORMAN, THIS IS FALSE AND FALSE ADVERTISING FOR THIS ARTICLE!

Attempting to build a custom brake system using metric bladder fittings proved successful harder than I thought. One of the last things I needed was a 12mm to 10mm adapter. It looked like that, but unfortunately it wasn't. While the male and female threads were correct, 12 turned out to be a bubble and 10 an inverted flare. Using a 21/64" drill bit, I machined the tapered saddle into a concave profile that would work for the job. Bubble ends seem to be the trend with modern systems and I was…
