2003 Trailblazer EXT

I am having serious problems with my brakes. The first issue that I had was that the truck would shake as I apllied the brakes. Found that the front right caliper was sticking. I have since then replaced all of the calipers, rotors, brake pads but I am blessed with this awefull squealing sound everytime I lightly apply the brakes to stop. If I mash down on the brake pedal, the squeal will go away.

Yesterday I could not stop during a heavy rainfall. I applied the brake and it felt like the truck was sliding. There was not enough rain on the road to hydroplane. The only thing that I have not replaced is the Master Cylinder, but I do not want to replace something unless I know how to test it first. Any suggestions?

Thanks,

Dave

Honestly, I believe you went overboard with replacing all of your calipers. I doubt they were all defective. With regards to your stopping problem, are you sure all of the air is out of the system ? Also, did you replace all of the rotors and pads at once ? The noise is most likely due to a glazed rotor or crappy parts.. Did you replace everything with factory parts or aftermarket junk ?
