hopefully someone can please help me.. i have a 2001 V6, no modifications, and im going thru several brake issues, mainly the rear. i replaced the pads, machined the rotors, new brake hardware, and the driver side rear caliper. but every single time, 2 days later i get a high pitched squeal from only the rear driverside. i take apart the brake system, put it back together, bam, squeal gone, 2 days later, back again. but now the squeal is accompanied by a "Thump" sound everytime my wheel makes a full rotation. and im only having issues on that side. neone? help?

Did you use a repair manual (Haynes/Chilton) when doing the job? Perhaps you missed something, or a step. I first thought that all vehicles' brakes were generally the same but began to notice differences. My Dodge's rear drums are simple enough. I would rule out the 'thump' being brake related unless you're positive the shoe isn't dragging and has been installed properly. One thing I would check for is a bad wheel bearing (easy to do yourself; jack up the wheel in question, place one hand under and the other on top of the tire and rock the tire/wheel towards your chest. If there is play and the wheel rocks, your bearing is shot). Are you using the right lube on the spring and around the cylinderto prevent noise/rust?

It's also possible the brake shoe might be dragging or your brake proportioning valve isn't sending the correct pressure to the required wheel.

Check the emergency brake and make sure it is disengaging all the way. Also, when was the last time you changed the rear axle gear oil? It'd be wise to visually inspect the pinion and ring gears for any wear that might be causing a thump sound.

With any luck you'll get this problem resolved. I can't say I've ever had brake issues like you mentioned, but I know I wouldn't be happy!!!!
