Hello everyone. I have an issue with the front brakes on an '05 Silverado. The brakes are sticking or virtually locking up. If you cycle the pedal several times the brakes will release enough for the truck to move, but you can tell they aren't back where they should be. Both calipers and pads were replaced and the system bled. It seems that something is holding pressure at the calipers and not allowing fluid to return to the master cylinder. Any ideas what it could be? Thanks for any help!!

 

Grease the slide pins and flush your brake system. If this doesn't fix it, i bet your master cylinder is going out.

 

Brake hoses

 

I did not mention that the right brake hose that runs from the caliper up was replaced. What else could it be? Master cylinder? Or the Brake Pressure Modulator Valve? Thanks!

 

I would try replacing the left brake hose first. Rust forms on the inside of the metal bracket on top the spindle which clamps and restricts the hose. Also you may need to do an abs bleed to properly clear the air from the system.
