I hear a very irritating clicking noise when I use my brakes.?

ok you probably do not need new brakes!!!!.......when the wear indicator hits the rotor it makes a sqeaking noise not a click....the fact that it is only one click tells me that the problem is that the brake pads are not releasing with the caliper.....most likely cause is bad brake hardware or a failure to grease the contact points when the brakes were done last.....if you have the ability to change your own brakes you can fix the problem yourself....just pull the pads of and grease the points where the metal of the pad slides on the caliper/pad holders.....it is pretty easy to see where they contact by the shiny metal.....also get some "disc brake quiet"...your favorite parts store should be able to help you find it and follow the instructions!!!

This is a Brake pad problem, I had the same problem in my old 1996 Nissan Altima. Midas had put literally the worst brake pads i have seen in my life, and whenever i'd initially apply the brakes, I would hear a click. So what i did was a few thousand miles later I bought high quality rotors and pads, and changed them myself, and voila, problem solved! The car doesn't click and it stops better.

You are probably looking at a minimum of a 300 (rotors and pads--never machine your rotors, its like 2/3 the price of a new one to machine it. Save yourself the headache and get rotors the same brand as the pad, and be done with it) dollar job if you repair it at a shop, or about 120 bucks if you do it yourself like i did. It is very easy!

It's probably loose brake pads or loose caliper cause by worn hardware.

When you apply the brakes, either the pads or caliper will move toward one side of the caliper bracket making a click or knocking noise. In rare cases, the caliper bracket bolts may have loosen up.

ON the brake pads and disc there is a small metal Gauge that makes a grinding noise when the pads and or disc need to be changed. Get the brakes checked asap.

looks like your calipers. The piston could be scraping against something making the clicking/crack noise very almost. common replace although, only replace that caliper. even although its perfect to interchange the two the front calipers to avert too plenty pulling on the hot caliper making you brake inconsistently. wish this helped.

It means you need new brake pads. That clacking is a little piece of metal they put in the pad to let you know you are close to burning your pads out completely and need new ones. If the clicking stops, that means the metal is gone and then the grinding will start. You do not want that. Get new pads, dude!
