2005 Chevrolet Silverado 2500HD going through rotors


Topic starter

I have a 2005 Chevy Silverado 2500HD 6.0l gas. I have been going through rotors every 3-6 months. I have replaced rotors, calipers, pads, flushed the brake system. I have bought the expensive rotors as well. I am very aware of this and don't brake hard so I don't think it is the way I am driving. My mechanic cant figure it out and I don't know what else to do.  What could be causing this?  Any help would be greatly appreciated. Thank you

Brakes aren't that complicated. Find a better mechanic.


How do the rotors fail? Do they warp? Get scored up badly?

What kind of pads are you using? Have you tried different pads when you changed rotors? Are the brakes releasing fully, any indication of excess heat?

They warp. the right front isn't braking as much as the rest of them.


do you drive with one foot on the accelerator, and one on the brake?

Do you still have the original brake hoses (17-18 years old)? If so the hose on that wheel could be deteriorating internally, reducing fluid flow when applying the brakes and preventing the caliper from releasing fully. I've had that happen.


Does this vehicle have ABS brakes??  If so, you need a bi-directional scanner to set the ABS solenoids in position to properly bleed the system.  If not, the caliper pistons can get stuck causing constant contact with the rotor thereby warping them prematurely. 

There is absolutely nothing about ABS solenoids for the manual brake bleed procedure in the service manual.
Bleeding can be done the good old fashioned way. ABS is designed to be fail-safe. If ABS quits, then brakes work normally. Power bleeding can be done with a scan tool, yes. But it's a convenience, not a requirement.

Cool! Thanks @mmj
