Good morning,
I would like to add to this great tutorial a important information based on my experience.
After changing the discs/pads, there was (not immediately) the appearance of a noise of metallic rattling located mainly on one of the two front wheels. This occurs when driving at low speed when passing over bumps and other irregularities in the road.
Someone also had this problem and described it very well in the following link: https://www.sportiveshyundai.fr/forum/vi...
This seems to be located on the brake disc/caliper assembly. It is not coming from the wheel nuts (I checked).
The vibrations produced on the wheel create a very unpleasant noise to hear of “metal part vibrating” (perhaps a “play” of the disc with the hub). Fortunately, this does not present any safety problem, it is just very annoying.
The person was able to solve their problem by changing the pads again AND the metal springs of the stirrup, the one who holds everything together.
When the spring is corroded on the caliper, how do I remove this spring?
Good morning,
(If your post is still relevant)
Normally a good flat screwdriver for prying (near the holes where the spring attaches) should do the trick.
When the springs are seized in the hole how to remove them already tried with penetrating oil nothing so what to do my ad a quote of 600 euros to change them thank you for your good ideas
Kind regards, Bruno
