Brakes I own a 91 Legend LS. A few days ago I had the front brake pads and rotors changed. Tonight the brakes were grinding and very hot. Also, I smell burning rubber and feel a vibration on the driver side. Should I change the booster or master cylinder?

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).

Brake pads are worn. That noise is the sound of the backing plate for the brake pads hitting the rotors. You will need to replace the pads and probablt the rotors. When the brakes go metal to metal like that it typically destroys the rotor.

good day, it maybe the right time for a good brake pad change, brake pads must be totally worn that it has a metal to metal contact already. hope this helps, have a nice day

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.

Were metallic brake pads installed? If they were and are hidhly aggressive, yes. Give them a few miles to smooth 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

Depending on how far you drive to work, If you can already see grooves in your rotors it is doubtful if yu will do more damage than has already been done! However, you are taking a chance if the brake light has been activated.

Did you check the rotors to see if they were cracked or 'thin' ? Rotors sometimes get really thin with use.And they can crack. Or as in one case that I know of there was sand between the rotor and the pads. The pads were also new. Removed the gravelly sand and they worked fine.

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.
