Bad grinding sound when braking

Outside of knowing how to change oil and air filter, I don't know much of anything else about fixing cars. I have a 2003 Tacoma with about 115,000 mi and I'm starting to have this unusual grinding sound that I've never heard before during the end of my braking (and kind of feels like the brakes are slipping). Anyone know what this problem is? I've never had my rotors turned or replace so could it be about time?

 

Take a look at your brake pads, u might need new brake pads

 

If I remember correctly from the past few brake changes, wouldn't it be making a high pitch hissing sound while driving?

 

sometimes it will. but its not uncommon to have it only when you brake

 

Alright, I'll give it a check then. Thanks.

 

I can't remember exactly how the tacoma is setup, but disc brakes have a 'wear indicator'- that's what causes the squeek/hissing sound. It's usually a metal piece that actually rubs againest the rotors causing the sqeek/hiss.

If that wear indicator is broken or missing - it won't make any noises.

Nitto - you'll also want to check the condition of your rotors. They might need to be 'turned'.

 

From the sounds of it you have worn the metal piece out that makes the high pitched noise when your brakes need to be replaced so now they are making that grinding sound because your pads are past worn out. So I would change them and have you rotors turned.

I did this to my truck a few years back but I didn't turn my rotors and it ate the new set up pads up pretty quick plus it doesn't stop as smoothly.
