Holy cow, your suspension is completely worn out! 
Plain to see how much movement there is in the radius rods in that second video - the rubber bushings are completely done - or maybe the rust has eaten out the centre of the mount...
I would think that if those bushings are that worn, then all the others are, too. Replace the lot: upper and lower control arm bushings, upper and lower ball joints and the radius rod bushings. Check the sterring rod and rod ends for play, too.
When its all done get a good alignment and go forth safely!

It looks like your sway bar is missing and steering rack boots torn too.
For parts, assuming you are in Europe try Brickwerks in the UK.
Also you might want to update the thread title to refer to front suspension rather than brake calipers

The YouTube video labeled "Front brake noise 1" shows the squeak coinciding with the radius rod movement.
I wonder if the hole that the radius rod passes through has been damaged enough that the metal sleeve is rubbing, metal on metal.
It's not too unusual to see that hole double the original size.

This is the wear levi is describing, on this one it's just starting to wear through the inner sleeve but if left too long the rod will start eating the frame.
(the portion that's missing is steel not rubber)
And the worn out bushings/sleeves with Powerflex replacements in the rear.

It is the right had end of the radius rod in photo 1, the hole in the left hand end is where the drop link for the sway bar is meant to go. Photo 2 is the tie rod end.

Sorry. Should have pointed out the picture I posted is of a Syncro's radius rod end, so it looks a bit different than yours but same idea.

As Mellow Yellow said, if you're in Europe get in touch with Brickwerks, if North America, VanCafe.
Good luck!

Show my silent...
thanks for the answers and thanks to all the members for the suggestions. I ordered all the silent blocks as soon as I get them up I'll let you know if I solve. |

You should check the procedure on how to charge the radius rod bushes first because you may need to remove the whole lower control arm (not sure on your early style radius rods) so it might be worth having new bushings for these as well.
Also check out getting a sway bar (aka anti roll bar) and associated parts as well.

that I can not solve. when I brake I hear a squeaking noise. I changed the front brake pads, all the rear braking system but the noise is always present. the noise seems to come from the right front wheel (passenger side). I blew the oil line but the noise remains. I made videos to understand the problem.
