Basic instructions. I mean, the Motive unit anyway, I believe assumes you have some knowledge of how the brake system functions and the various components involved.

Hmm, don't remember, and i just took the unit to work to perform tomorrow on a unit at work. I have 2 adapter cap, 1103 and the 1100.
But you can see this video here:

All my knowledge is from the forum and google. What advice can you provide in flushing brake fluid? Thanks.

I prefer to keep the unit clean and clear of brake fluid.

Remove the cover from the brake fluid reservoir.

Remove as much fluid as you can from the reservoir without uncovering the suction.

Fill the reservoir to the brim with fresh fluid.

Attach the bleeder cap adapter to the reservoir.

Make up the connection to the pressure bleeder.

I only pressurize the unit to about 10 pounds.

Start at the right rear and crack the bleeder valve on the caliper.

Watch the level in the reservoir and in your catch bottle you've attached to the bleeder. You can't let the reservoir empty or you'll force air into the system

I bleed 1/4 Liter which is more than required. Basically, the volume of the reservoir is likely enough.

You'll have to SLOWLY depressurize the system to refill for each caliper. Let rear, front right and then left front.

Alternately, you can fill the unit bottle with a few Liters of fresh fluid and can just move from caliper to caliper.

If you are unmounting the caliper and removing the brake pads, make sure you take positive action to prevent the caliper piston from moving under pressure. They can move sufficiently to dislodge from the caliper seal and boot. Otherwise, you can depressurize the system when moving between calipers to mitigate this problem.

Thank you so much for such a detailed description of the procedure. One thing I would like to get more information is the "slowly" depressurized the bleeder. How to do that? By slowly unscrewing the bleeder cap? Thanks.

My dealer did a brake flush for me in the neighborhood of $100+. That pencils out for me to just have it done... with a loaner a nice review

My dealer quotes me $185, but I really want to do it myself. Thanks.

My indy charges $107 for the brake flush. This requires me to drive to them, wait for the service, and then drive back home. It is not that much compared to the other jobs but you can do the flush yourself in 30 minutes and about $10 in fluid. Also, the dealerships near me don't usually give you loaners unless the job is above a certain amount of hours or in some cases, they don't give you loaners if you didn't buy the car from them.
