I have a 2001 Tahoe 4WD with about 150,000 miles. When braking there is a very loud grinding noise; it seems like its louder when it's cold outside. There is still plenty of brake pad left; however, the left caliper was very difficult to remove. Could this be the cause of the noise? Also can the need for an alignment cause noise when braking?


No, an alignment will not cause any noises, just tire wear. If the caliper was hard to remove it's possible the pads are sticking against the rotor and overheating causing glazing. You also may want to check for any rub marks on the rotor; it's possible your caliper may be hitting the rust buildup on the rotor when braking. I recommend having the caliper cleaned, lubed, and inspected for a binding piston; if the pads are glazed, replace them.
