Brake bleed with Motiv
#16
Burning Brakes
Yeah I had that issue when I decided to use it wet. I had done a whole 987 bleed dry, and a few times on the 964. Figured I'd go wet to get the clutch bled, back under the car, and thought I heard the neighbor's sprinklers on. Noooope. Cleaned it up, added new hoses. The burst lines were the originals from the mid-2000s when the unit was purchased. Lesson learned.

I guess if you wanted to compare and be real scientific you would need to take into account that multiple pressurization/ depressurization cycles weaken the bleeder hose and reservoir as well. Like aircrafts, they may have a limited number of cycles before something breaks. Just a thought.

I'd do the wet method simply to save time. Fill it up and go through and bleed each nipple. Versus, reservoir is low, depressurize, unscrew, fill up, pressurize, repeat. It's less time to clean the Motiv than constantly go through the dry method steps over and over.

All this talk of blowing stuff up. Why use the motive bleeder at all! Pump! Hold! Pump again! Hold..... Just use the pedal pump method. No blowing up hoses, no clean up. Just a sore leg and the need for a second person. With all things equal it takes forever but doesn’t involve the possibility of things breaking. What if the bleeder is too tight and breaks off in the caliper, better not bleed your brakes at all since something expensive could break.

Motiv does have an all metal cap to help prevent the cap from blowing off like that. Honestly have never worried about anything blowing up like that though, just keep an eye on the PSI and you are good to go.

I bleed my brakes/hydraulic system with a dry Motiv and it works great. I haven't had issues with anything exploding or leaking, if I see a hose that looks a bit dodgy I just replace it. No issues yet. *knock on wood*

I do a lot of brake fluid flushes on many models and always use the dry method. The quick connect has a check valve so just remove that and fill the reservoir to the top and check after each corner. This way you don't need to pump it up as much each time. It takes far less time to check and refill the fluid tan it does to clean the unit after.

I don’t get buying a bleeder if your going to use the dry method. Couldn’t you just get a cheap 1/4” regulator with a gauge and a spare cap and use your air compressor?
