So I was flushing the brakes after changing my pads and rotors. I figured it was time for new brake fluid. But I screwed up! On the last brake I was flushing, I forgot to keep the master brake cylinder reservoir topped off! In fact, I let the brake master cylinder run dry which meant I introduced air into the brake master cylinder. This traditionally would require uninstalling the brake master cylinder, connecting hoses to its bottom drain port lines and running those to the reservoir with the master brake cylinder clamped in a vice and then pumping in the piston with a screw driver to cause the brake fluid to move out of the brake master cylinder and into the reservoir which would flush out all air bubbles over time - this process being called a bench bleed to remove the air from the master cylinder. However, after extensive research, I discovered a little known method for bleeding the brake master cylinder while it is still on car and better yet, without having to remove ANY brake lines or hoses! You don't even need a brake master cylinder bleeder kit! All you need is 10ft of vinyl hose! You simply connect the hose up to the front left caliper bleeder nipple and then run the hose into the brake master cylinder fluid reservoir. Then you top off the reservoir and tape the hose in place if needed to ensure it doesn't come out. Now, you pump your brakes while making sure to keep the brake master cylinder reservoir topped off with fluid so you don't introduce more air into the system. Then, after pumping the brakes (never pumping the brake petal all the way to the ground but only 2/3rd of the way tops else you risk breaking the master cylinder - or so I read) you eventually see all of the air gone from your clear vinyl hose and just see fluid running through! Then you know you have successfully removed all air from the master cylinder. Well you need to keep going even after that just about 50 or so more pumps. The more pumps the better as you are enabling the master cylinder trapped air pockets to bubble and work their way out of the master cylinder over repeated patting of the brake petal over time. After this process is done, flush all the brakes at each of the 3 remaining wheels beginning with the rear right wheel, then the rear left wheel, then the front right wheel. You can do this with any brake bleeding method - gravity, partner, vacuum pump, pressure bleeding, etc. Once all brakes are fully bled, you should be back in business! My car brakes were PERFECT after this process. Also, as a side note, when flushing the fluid in the first step from the caliper and back into the reservoir, I put a coffee strainer on the end of the hose to ensure no particles got into the reservoir. Also, the fluid I was cycling back into the reservoir was new fluid as I had already flushed all my lines with new fluid 2 days prior. So the fluid was very clean still.
