Default breaking-in brakes

Dumb question...
I recently did a brake job on my 02 Durango (new: pads, rotors, shoes & springs, drums). Braking is great but it's a little noisy during the moments that the truck stops completely (truck's inertia is completely stopped ) and when I take my foot off the pedal. Will this go away once the brakes are bedded?

Do you mean squealing sounds? Or rubbing sounds? Either way, I've found that if you speed up and stomp on the brakes really hard the sounds will go away. I do that when it rains to get rid of the rust build up from the night before .

you may have just gotten some grease on the brake parts.. spray it down with some break cleaner and see if the problem goes away.. did you just replace the parts or did you do a full job by spraying down the Back of the pads with disk break quite and lubing the calipers with brake lube??

I didn't spray anything. I did use lube on the back of the pads and other metal contacts like where the pads set on the mounting bracket, caliper bolts, etc. That stuff is pretty messy, so I could have gotten it on the rotor/pad contact surfaces I guess.
The noise isn't a squeal, it's more of a rubbing sound at the very second that the motion of the rotors are stopped completely. Like I stated earlier, the truck is braking great, it's just annoying to hear.

Also did you clean the new rotors before installation to get the oil off?

No, I didn't even think about it.

When new rotors are bought they are covered in a grease that is very light. You are supposed to clean it off with brake cleaner before installation. Next clean the new pads. Next is the slides on the knuckle. You are supposed to sand out the indents (nice and flat) and grease them before you install the pads on the knuckle so they slide and not stick in the holes that are there. Next you are supposed to clean and grease the slide pins and ensure the pads are sliding correctly on the knuckle slides.

Sounds like you might have ruined your rotors. I would pull them back off and clean ans scratch them up with some light sand papper. Next clean and sand the new pads, and then install like I told you.

Or simply take it in to a shop and have them done right.

I've seen brake jobs work fine without doing any of the fancy stuff.. I can be a bit of a perfectionist when I do jobs but the mechanics will all still work down there.. In my own opinion, you should be fine (without seeing it), but I would spray some brake cleaner all around the rotors.. make sure the lug nuts are tight too..

I've seen people do "non-fancy stuff" and totally regreted it. Can it be done, well most likely, but should it be done the easy way, NO.


When doing brake work I never faulter because it's your life as well as everyone in your truck, or in your path that gets hurt. Just my 2 cents......

I agree. I took them apart, cleaned them and tried to smooth out the indents with a file and sand paper. The noise is gone. But I do have a slight squeal now... Could that be from sanding the rotors/pads or maybe I didn't get enough grease on the other parts?
I feel good about the braking power, just hate any type of unnecessary noise.
