probably a stone caught in the brakes, it will eventually go away, but may damage your brake rotor, worst case.
if it really annoys you, listen to what wheel it is coming from & remove the dust plate from the back & the stone should fall out (if that's what it is)
replace the brakes.grinding is caused by worn out, metal to metal pads grabbing is caused by the metal being hot and sticking
Permanent...once the metal has oxidised -there is no way to reverse it.
The ginger garlic paste may have turned green after grinding in a stainless steel jar because of a reaction between the garlic, ginger, and the metal in the bowl. This is also why a person should never mix mayonnaise with other foods in a stainless steel bowl. The acid mixes with the metal to form a toxic substance.
I didn't think it was possible but apparently it is (from grinding stainless steel, that is). I guess if the chromium metal gets hot enough from the friction of the grinding wheel, then some of the chrome will convert to chrome 6. Below is a link. See Table 2. Also see the authors comment before Table 2: "Surprisingly the highest numbers are from arc-air, grinding and welding". The report doesn't give many details. it would have been nice to know if maybe these welders were working in an area with another possible source of chrome 6 such as welding.
Such chemicals are called as catalysts. Example:- Nickel metal is widely used as a catalyst.
A grinding noise when braking can occur when the brake pads are going bad. You are hearing the brake grinding on the metal discs.
filings
swarf
By grinding or filing the metal.
When grinding metal you should wear eye protection. A mask to filter metal particles from the air you breath may be appropriate if you are doing work that will release very small metal particles, and if the metal is chemically hazardous.
Check if muffler is loose, check if rear brakes are worn out & grinding
Check the brake pads on that wheel, it sounds like you have metal on metal if the grinding is only when you are stoping or right after you release the brake and start rolling
A bad transmission. The sound is from metal grinding on eachother.
try checking your engine for loose things
Yes, by grinding the zinc metal you can get the zinc powder. Which type of grinder we can use
Its kind of a grinding screeching metal on metal noise.
Could be a bad wheel bearing.
