Hi guys,
I live in Évora, a small, old, beautiful Portuguese town, but with very very bad roads. Every road in the historical part of the city are made of rocks, disposed in a very irregular way, as it was centuries ago, something like this:
A while ago, I started to ear a "banging" noise when driving over roads with this pavement, but as soon as press slightly the brake pedal, the noise go awya, but if pulling the hand-brake, the noise continues.
I checked the brakes several times looking for the cause of this with no success, the pads are ok, have no play, everything seems ok... Today I decided to give it another go, and I noticed that if I "twist" the sliding part of the calliper, it is possible to see some play in the sliding pins. After removing the sliding part of the calliper, it is possible to see some play in sliding pins, and the actually make some noise when "toying" with them from one side to the other, so, I guess that I found the culprit...
Now, my question, is it normal for the sliding pins to present some play, allowing them to play from one side to the other up to the point of making noise?
The sliding pins are easy to replace, I wonder if it is the sliding pins that are worn, or the part where the sliding pins are installed...
Here are a couple of videos that I shot with my cell phone, they are very bad, but they give an idea of what I am talking:
