KSDP, Open both caps on the Bosch Hydro-Max booster. Using a vacuum pump evacuate all the fluid in both chambers. Refill the Bosch Hydro-Max with clean fluid.
I will review the 2-man method.
You will need a 24"-30" length of clear tubing I believe it's 1/4" internal diameter. I used a black hose. Place the hose into a 2L soda bottle.
Proceed to the right rear bleeder and with the assistance of a helper, have the person apply the brake and ask them to hold it and not to let up on the pedal until told to do so. The engine does not need to be running. The emergency pump will provide enough pressure.
Crack the bleeder screw and allow the fluid to continue to flow until it shows clear through the tube or as it enters the bottle. When clean, close the bleeder. Tell the pedal stomper - OK! (You could use an FRS or shout really loud!)
Refill the Hydro-Max at each flush cycle. Hint: Use a small mirror to observe the fluid level.
Repeat on the left side.
Refill
Proceed to the front axle, right front typically and repeat the process that you did on the rear.
Refill
Complete the flush at the left front and refill the Hydro-Max up to the bottom of the opening on the tank. Down from the opening about ~1/2".
That's it.
Start the machine and pump up the brake pedal.
One man method can be easily accomplished using Oemy's Super Speed Bleeders.
Don't forget to refill when bleeding each corner if you don't have a way to refill the Hydro-Max automatically.
Oemy has a great bleeding procedure on his website. Check out that resource as well.
