I've had possessed brakes for the past 6 months, and i'd like to get rid of the squeal before i try to sell my 2000 blazer zr2. I have new pads and newly machined rotors...but they still squeak and its driving me nuts. The noise isn't constant at all, it seems to be loudest at the start of a trip then quiets down later. Also, if i lightly hold the pedal down for 5 seconds sometimes they dont squeal when i stop. I am confused and I don't get it, what the hells going on? Thanks.

Good quality and the right kind of brake pads?
Are you pads worn out or down to the squealler?

The brakes originally started to squeal about 6 months after i bought it, so I replaced the pads(with monroe pads) and had the rotors turned...they still squealed, and now I replaced the pads with some $40 NAPA ones..I know theyre the cheap ones but I've had the same problem with 3 sets.

Are you using the good oem type ceramic pads?
I always go with the dealer OEM pads or the wager best grade cermanic pads.
And have no squeal problems.
Always use the installation hardware that comes with good pads and lube all sliding hardware.
Hard or excessive braking or bronco willie stops tends to glaze pads and stir up brake squeal.
Also the wrong rotor turning cut can add to the problem.
Good Luck

There's your clue.
Like MT said, the vehicle came with ceramic pads, use them. Good quality pads are slotted, chamfered, and have shims riveted to the back side. Anything less, stay away. Always replace all hardware and use a good synthetic lubricant. Have a reputable machine shop resurface the rotors and make sure they put a non-directional finish on them when they're done resurfacing. Caliper pistons should move freely in the bores, if not, replace the calipers. If you "cut corners" on brake repairs, they will most likely squeek, indicating an "economy" job.

Doesnt that drive you crazy.. I went thru the same scenario.. new metallic pads and turned rotors.. then went with new rotors and ceramic pads.. still then what finally solved it was the caliper pins.. replace them and noise be gone... really cheap and u can replace them without taking the whole thing apart... try it
