    Thank you for the video very helpful my break fluid is very dark so maybe it’s the last thing to check with is the master cylinder and the pedal goes to the floor slowly but when I press the breaks fast the get hard then like two seconds they go slowly to the floor I don’t see no leaks and fluid it to the max never had leaking problems thank you for the great step by step information

    There could also be air in an otherwise good master cylinder so might need to be bled as well, also if too much fluid leaked out there could be air in the ABS module which unfortunately requires a scan tool with ABS function to remove

    Our mechanic was looking at our car and said the ABS module had a leak. The pedal is super soft, goes straight to the floor, and comes back up slow. It makes an airy kinda sound when you push it down, and when you get to the floor it just drives down the rest of the way with no resistance. It’s a 2010 RT charger. We bled the brakes swapped out 3 ABS modules and bled the brakes between each module, the problem still occurs. The mechanic told us there was a leak in the last module, and the second module was good but the screw on one of the lines was rethreaded, but the brake fluid wasn’t leaking in the second module. We did most of these on the list but we didn’t check the cylinder. We’ll try it next time.

    Great move - well explained...
    Changed slave cylinder, brake pipes, brakes, pads and all fluid was out.
    Filled up with new fluid, bleed each wheel until no air. Filled up with fluid from bleedscrew in slave cylinder (to get air out from master cylinder?) and then used scan tool to get air from ABS
    Neww at scan tool, think i got it right...
    When car dont have ignition the brake is ok, when ignition pedal goes to floor when brake..
    One of this 5 issues in this movieclip its must be? mean good brakes no ignintion, bad brakes when ignition on...

    Also an internally leaking ABS module can make the pedal sink to the floor just like a failed master cylinder would but a little slower.

    I was going 55 mph around a curve yesterday and lost brake pressure for a little bit. Pumped them until i got pressure again. Ended up being a 6th reason not mentioned.
    My left rear brake pad got so thin it slipped out of the caliper and got lodged into rotor and caliper frame. Caliper pistons became the pad. Got all messed up.
    So, theres a 6th reason.

    It's usually a rear cylinder. Now & then it's a leaky pipe or a sticking front caliper - but generally it's a leaking rear cylinder.

    Hi, I watched many videos already since I found your channel yesterday. This channel is why I love youtube and the internet. Great information well presented straight to the point.
    But I have to say the channel really needs playlists. It would make finding the content much easier. A general playlist for videos like what is X part or what does X part does. And playlists by car model or brand. You know the videos you released better than I do so you should have a better idea of how to organise them into playlists.
    You still earned yourself a subscriber! Keep up the good work very informative channel.

      Make sure the parts store gave you the caliper for the correct side. You can check this by looking at where the bleeder screw is on the caliper. It should be close to the top. Many of these calipers will fit either side , but if its on the wrong side , you won't be able to bleed the air out of it. Good luck , l hope you find the trouble.
