I just did 6 complete overhauls of entire brake systems on ground support equipment for aircraft. I replaced the master cylinders, the main brake fluid reservoirs, entire lines from the systems, calipers, wheel hubs races and bearings. I bled the systems by gravity first then by suction using the air pump assisted method. The specific pressure for the equipment must be 725 psi or better. All 6 systems have 800+. My co workers used the one, two, and three hold the pedal to the floor method. I then opened one bleeder at a time and closed it before they let off the pedal. I ensured and verified there was no air in the system. Even the bleeders threads were sealed with sealant to ensure no air was entering the system.
3 of the 6 vehicles came back with soft pedal. We rebled those systems and verified no leaks were present anywhere.
I consider myself very proficient in repairing and troubleshooting these brake systems. Yet the soft pedal reoccurs. What could it possibly be?
where would you go after you replaced the master cylinder and the pedal still sinks to the floor after pumping it up

After watch your video, I figure out I left air in my brake line, problem solved, you saved my day, thank you very much 🙏
Thanks
Thanks brother
Thank you very much excellent video
This is 1 worth keeping 👍
Good video. Have you ever had a brake booster check valve go bad? If so, how did you test the check valve? Thanks for your time.
Can you show a video tutorial on how to “auto bleed” with scanner and quick video of how to check the booster for leaks like you stated.
Awesome show, what brand is the scan tool in this show.
Thanks god bless
I just replaced brake booster on dodge caravan 2013 but breaking lights stay on . Any idea what is the problem. Thank you
Don’t know if you answered back to question but I recently had a brake problem when I was drive my brakes went out on me I will admit my brakes was scratching for a while so I know I need brakes pads then I noticed my fluid wasn’t in there when I put some in so can that be the reason because my pads being gone ??
I changed pads rotors and dot4 fluid but break pedal vibraiting when using it and hard to press. Why is that? Thank you
Mid to late '90s Chevrolet notorious for soft or spongy pedal
Can you do the same documentary on steering pumps
Muchas gracias! En español, Genial!!! 😊
Could also be the rubber lines....
So I'm having some brake issues on my chevy equinox I'm having to pump the brakes for the brakes to slow the car and come to a stop
I have a 2014 chevrolet malibu 2.5 engine that starts runs but after a while it dies and won't start I already replaced the crankshaft position sensor but dies the same thing can someone help me out thank you
My brake pedal doesn't return all the way almost but not all the way .any help is much appreciated
What if the pedal squeaks? What could be wrong?
Can i just replace the rubber of the master cylinder?
Great video.. can a bad or aerated master cylinder cause trouble with releasing the brakes as well? Also I have bled all my calipers a number of times and there is no air in them could the master cylinder still have air in it?
+@Dnasty1 We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I changed a front brake caliper on my Accord 2014 and it sinks even after 2 bottle flushing. Before that was everything great. When the car is off the pedal get hard but when i turn the engine on it sinks. What can i do, pls?
How funny and ironic to see this video. I recently experienced where my foot seems like it keeps going further toward the floor to stop the car. Even my master cylinder was low with fluid. I added fluid thinking all was now well. Few weeks went by and noticed that the fluid is low again. So I have a leak somewhere but I cannot find it anywhere. So I am thinking it is the master cylinder.
W can happen when transmission fluid is added to brake fluid
My brakes pedal operates normally until it’s 4th-6th brake then it won’t release pressure and I end up spinning my rear tires and can’t move
After changing all that it still wasn't working. It was the brake sensor. Breaks were activating and making that humming noise like I was driving on ice.
Master cylinder change by no change in pedal distance

Umm anyone else getting language changes from english to spanish
Thanks for noticing! This is a new CZcams feature we are trying out on a few videos! Alternate language audio tracks are selectable under the gear icon settings!
Of course you cannot replace the seal instead of a whole master cylinder?
That fluid look horrible it should be clear like water
Simply no logical diagnostic strategy here!
