What causes the brake on a GMC Sierra to stick?
The brake hose that attaches to the Sierra’s caliper will often cause the brakes to stick. They may appear to be fine on the outside, but can break apart and collect debris on the inside. When this happens, it effectively traps pressure in the line. This keeps the brakes from releasing all of the way, and they stick as a result.
Are there any brake lines that need replacement?
The brake lines in 1999-2007 GMT800 Silverado’s, Sierra’s, and Suburbans are very prone to rusting out and needing replacement. For individuals who live in “salt” states, where cities commonly salt the roads to prevent ice, the brake line rusting is even more common.

Why do I need to replace my brake caliper?
Your Sierra’s disk brakes use pistons to push the brake pad into the rotor. These pistons have a rubber seal around them. This seal can go bad and the piston will start to lose its free movement. If this is the case, the caliper will almost always need to be replaced.

Why are the brakes soft on my Chevy Silverado?
Air trapped in the lines, calipers or wheel cylinders will make the pedal feel soft and spongy. Air is compressible, so when the brakes are applied any air bubbles in the system must first be compressed before the hydraulic fluid will transmit pressure to apply the brakes.
What should I do if my GM brakes are bleeding?
