How to fix squeaking brakes for free - on Hyundai ix20, but works on most cars

Turn on subtitles to see comments during the video.
This video demonstrates a case when the squeaking brake can be fixed by simply cleaning and greasing the braking pads that are rusty and stuck to the caliper. Even though the disc is warped this method eliminated the squeaking completely because the pads were now able to retract far enough to not touch the warped disc while spinning.
Obviously at the end of the day it all depends on how much the disc is warped.
The steps are demonstrated on Hyundai ix20, however the principle applies to any other car.

Using the wrong grease, should be copper based.

thanks for your comment, copper is fine too - i tried copper for 2 seasons , but I find this one better and it is also recommended on forums (but half of the crowd uses copper alright:) , even the paste manufacturer seems to be recommending it - ruclips.net/video/n9A4DS9Q3Jg/видео.html . Anyway - works very well for me, hence Ii put it in the video:)
