2007 GMC Sierra Brake problem?

[Joshua]

2007 GMC Sierra brake scoring the brakes work fine but my right front rotor has a deep cut in it i have taken it apart and there is nothing digging into it. There is no squeaking,grinding, there is no lose from the brakes at all but a deep cut WTF?

Sometime in the past, there might of been something caught between your brake pad and rotor that caused the deep cuts. I had the same problem with my Jimmy and ended up replacing the Rotors on both sides with cross drilled and slotted rotors with ceramic pads (not that expensive any more). Note that the ceramic pads don't do well stopping until there broken in and warmed up, so take caution when upgrading to ceramic brakes.

Since ceramic pads were first used on a few original equipment applications in 1985, friction materials that contain ceramic formulations have become recognized for their desirable blend of traits. These pads use ceramic compounds and copper fibers in place of the semi-metallic pad's steel fibers. This allows the ceramic pads to handle high brake temperatures with less heat fade, provide faster recovery after the stop, and generate less dust and wear on both the pads and rotors. And from a comfort standpoint, ceramic compounds provide much quieter braking because the ceramic compound helps dampen noise by generating a frequency beyond the human hearing range.

Another characteristic that makes ceramic materials attractive is the absence of noticeable dust. All brake pads produce dust as they wear. The ingredients in ceramic compounds produce a light colored dust that is much less noticeable and less likely to stick to the wheels. Consequently, wheels and tires maintain a cleaner appearance longer.

Ceramic pads meet or exceed all original equipment standards for durability, stopping distance and noise. According to durability tests, ceramic compounds extend brake life compared to most other semi-metallic and organic materials and outlast other premium pad materials by a significant margin - with no sacrifice in noise control, pad life or braking performance.

This is quite an improvement over organic and semi-metallic brake materials that typically sacrifice pad life to reduce noise, or vice versa.

Good luck and might as well go for the upgrades, you'll enjoy it better and last much longer.
