2000 K2500 vibration

[daysvilleman]

Hello I am new to this site, Just like to say hello to everyone.
Anyways I have a 2000 K2500 that i am at wits end with. I have been having rear brake issues for quite sometime.I have replaced the cylinders, pads,drums adjusters and all hardware. However What seems to happen is When i take the brakes apart and inspect them everything looks good.I will put them together and adjust them out. they will work good for probably 10 miles but then I will start to get major pulsation in the rear brake to the point where the whole truck with shake. THe rear brakes will then squeal and lock towards the end of your stop. It almost feels like something is out of balance because i always feel a slight vibration. I just have the driveshaft balanced and u joints replaced as well. If anyone may have any suggestions they would be greatly appreciated

welcome to the forum... have you replace and of the rubber brake lines you could have one going bad. and you can not just look at them to see if they are ok. you have to take them off and then look at them

the type of material on the brake shoe can be affected by the heat and the truck may not like it.....
did you switch from organic to full metallic or anything like that? also open a bleeder and see what the fluid looks like, and if the pedal pushes easy when its open, you may need to flush the fluid
