Ok, keep in mind this noise I'm going to talk about has been present before/after my recent front brake/rotor and rear shoe/drum replacements.

Whenever I let off the brake, theres a LOUD squeek. I checked, nothing is grinding into the rotors or the drums, they're fine and like I said it was happening before too. Is it just the mechanism doing this? It's nothing more than annoying, and now that I have a great looking truck, letting off the brake and hearing this shrill sound is just driving me nuts. Is it safe to take some WD40 to the parts or what should I do? I didn't replace the calipers when I replaced the front brakes and rotors adn I'm wondering if thats it.

1. NEVER lubricate brakes with anything that reduces friction

2. Check the brake pedal and brake linkage, is the sound coming from INSIDE, or outside?

I had a squeak coming from my brake pedal linkage, up under the dash, I coulda swore it was coming from outside the truck, but it wasn't.

Have a friend accompany you to a parking lot, and have them check if the noise is coming from outside, and if so, where, then find the cause.

its possible you have a slightly sticky caliper thats not realeasing pressure fast enough.

 

either that or it could be the drums in the rear. there are a few contact points inside the drums where the shoes contact the backing plate that hav eto be lubed with high temp grease. These could be bone dry so when you let off the brake and the springs pull the shoes back they squeak from the contact with the backing plate.

 

I had a problem simulor to this with a cavalier. The drums were out of round(new) took them to be lathed, the guy lathe them down a little under recomendation problem fixed. I don't know if this helps you or not.
