Installed new front pads and brakes grind when applied what did i do wrong

Hi Benjamin:
I'd be getting the brakes checked (or actually check them myself).
That involves getting the vehicle jacked up, removing the wheels, and visually inspecting the brake pads and discs.
PLEASE! This is a safety issue and you NEED good brakes.

Don't delay/ Get them checked.
Best to you.

A grinding or rumbling noise can also be symptoms of a wheel bearing or constant velocity joint in a driveshaft. A worn wheel bearing can also cause a 'whistling' sound (as can a worn CV joint).

A grinding noise with brakes is either worn pads causing metal to metal contact on the brake disk/rotor, or the brake backing plate catching on a spinning rotor ... or a loose/missing anti squeal brake shim (they stop the pads from rattling and vibrating).

However, as you say a mechanic has looked at the brakes and can't find anything wrong .. I think I would begin to suspect a wheel bearing or constant velocity joint on the driveshaft (front wheel drive cars).

Worn brakes

Try checking the rear brakes.

if the rotors were not turned when this was done you will get wear-in grinding noise..the uneven surface will i time eat the pad to fit the rotor surface..next time get the rotors tuned or replaced for good surfaces.. good luck..

you need to check to see if the new brake pads have been fitted correctly, some brake pads may go on either way & the metal side is on the rotor......hope this helps......cheers.

Usually a grinding noise in a disc brake is caused from a rotor with a raised edge that froms from normal wear. The raised edge is not a big deal until you install NEW disc brake pads. All of the sudden you have a grinding noise everytime you apply the brake because the NEW disc pad is being ground down but the raised surface created from the OLD Disc Brake Pad. Most of the time the Brake repair shops turn rotors on the car when the pads are replaced and this grinding symptom does not manifest itself.

On and OLD set of disc brake pads over time that raised area on the rotor starts to flake / rust / corrode and can come in contact with the brake disc pad when the brakes are applied.


Hope this explains it well enough.

Thanks for using FixYa.

The grinding noise probably means you need to put new brakes on. If you fill the brake fluid reservoir, and then change the brakes, the new fluid will run out anyways, because the new brakes will have to be put in, and the fluid will run out.

from my experience its sounds like ur front rotors may need resurfaceing...if ur doing that...may as well replace the brakes on the front as well...sometimes glazed front brake pads may make a sound but never heard of it as a grind, usually its a squeal...have ur dealer check ur rotors for hot spots in which u would need them replaced if they are overheated..also check the front pads for cracked brake pad material

Sounds like your brake calibers are sticking. Get new ones and new pads. You probably should get new rotors also because with the dragging calibers they most likely got hot and are warped. Search on ebay and www.rockauto.com . I personally use power stop drilled and slotted rotors with mid grade pads. You can probably get a whole kit.
