I recently had both my brake pads (front and rear) and rotors (front and rear) replaced on my Chervrolet Blazer because I was getting a squeeling sound when I would brake. After I replaced both the pads and rotors, I was told to wait 150 miles so that they could wear in before the new squeeling would stop. It has now been 1,000 miles and I still hear the squeeling. Is this normal? Should I take my vehicle back in to have it looked at again?

Sounds like you are doing a lot of slow braking and have glazed the pads over. This causes the squeeling. I would return to the dealer and tell them you have the same complaint again.
What they need to do is use rough sandpaper and rough up your pads and rotors. Then set the brakes in. This is a process of repeated braked until almost coming to a stop over and over until the rotors are really hot then driving until they cool off.
Should prevent the sequealing, but first they have to break the glaze.

While doing your brake job did you do the following: On the non -friction side of the disc brake pad apply a liberal amount of NAPA - CRC Brake Quiet before putting the pads back onto the calipers? This is a red colored high temp silicone material . It's necessary to apply this material to cancel out pad-disc harmonics and squeal. Some less expensive pads do not come with the thin metal plate covered with high temp tape on the non-friction side of the pad either. This plate also helps to eliminate squeal. Even if the thin plate is there still use the CRC Chemical Brake Quiet and you'll be fine. This is off the beaten path somewhat but In the past in some GM cars (Pontiac Grand Am's GT Coups) GM has recommended higher tire pressures 5 psi less than the inflation pressure listed on the TIRE not the doorpost.The reason for this is to cancel brake harmonics.

You should never have a noise coming from your brakes with new pads and new rotors or turned rotors, whoever says that hasn't worked on many cars. I have installed many sets in my time, you need to check and see if the automatic warning tabs are bent back to the correct position, if they did not do this when they were installed you will get a noise, standard procedure on some makes and models. There is no brake in time when ever thing is new, stay away from that mechanic.

Hi! There is a red paste called "stop squeak" that should have been applied to the brake pads before they installed it on your blazer. If you had just the squeaking problem and you replaced the pads and rotors then you probably did not need a replacement, these guys were just supposed to apply stop squeak to the pads. You should take it back and ask them to do that for you...and yes, don't pay anything extra for that.

Some brake noise is common. If the disc pads were not tightened properly in the caliper assembly this can cause squeeling. What brand and price are the disc pads ......... this alone can cause brake squeel. Return the vehicle to the repair shop and discuss your problem.

Usually this happens because the brake pads are not the right ones. I.E, they are using noname craps that cost less but are harder instead of the normal pads, from the manufacturer of the car.
I think you should go to the dealer and report that and if they don't fix it call the car maker. They will definitely have a "customer phone" listed on their site and the dealer will most surely call you in 10 minutes to change the pads and fix the crap he's done! It worked for me with Renault!

new brakes require the break in 30/30/30 rule..30 stops from 30 mph in 30 min.. it heats them up so they dont glaze over.. most people take it easy with new brakes. wrong....go back and have the roughed up...there is also a paste and anti sqeel clips on the pads..lots of shops leave the off cause they r a pain to put on....good luk
