Default Do I need new rear brake pads?

Hello all. I have noticed that while coming to a stop and am down to something like 5 MPH (in other words, a slow crawl) it feels like my brake power comes in...waves. Like it wants to brake a little better...then not...then better. Almost like it's from the drum itself or something. To add to that, I have noticed a sort of screech that I believe is also coming from the bad brakes. It too only happens at that very slow speed and it only does it a little bit. I haven't looked yet but, could it be that the pads are worn down to nothing?

Thanks all!

Edit: finally checked the back (spinning the tire) and found that the left side spins about two rotations before stopping and the right side can't be free spun at all....

UPDATE:


Got the drum off and took a look. The wear pattern is weird on the pads. At the top, it is real rough. In the middle area of the pad it is a nice smooth, at the bottom it is rough like it is at the top. Looking inside the drum it looks and feels smooth. A neighbor stopped over and was talking to me and swears up and down that the drum is out of round. Could it be? Would this be why I feel my break power increase and decrease in one breaking period?

Yes! Sounds like you need brakes in the front and rear. The screeching sound is the wear indicators on the front pads and if it's fading like that you need to check all the way around. I don't go cheap on brakes because obviously they are very important. Have you noticed you need to add fluid to the master cylinder?

Have needed to add any fluid, no. Will double check tomorrow just to be sure though. Will also check all pads. Assuming I can get the drum open haha

Jack up the rear of the truck, chock the front wheels, and while in neutral spin each rear tire, there should be a slight drag, if not you can either try adjusting the adjuster or pull the wheel and remove the drum to visually check the rear shoes.

A squeak when stopping doesn't necessarily mean the brake pads (front) are worn down, more in a 4x4 than a 2wd sand or debris can get between the pads and rotors and cause a squeal.

Pull the front wheels off and check the pads, also check the rotors, any visual signs of ridges or grooves and you probably would need rotors, most people won;t bother having the rotors machined as new ones are pretty cheap, unless you get OEM rotors.

if the drum is stuck on there find a 12mm bolt head. Im not sure on thread pitch I just pulled one off and there are threaded holes in the drum you can screw the bolt in and will pop it off for you. just a little helper when they get rusty

Squealing brake pads can tear up your rotors and drums very fast, resulting in very expensive brake job.

Replacing pads only might be $200. Replacing the rotors and drums at the same time can run you $800 and up because of all the extra labor. That extra money is what you spend for putting it off.

Usually if you think you need brakes you do. I just did mine about 8 months ago and I replaced everything front and rear,then a couple weeks ago I noticed my truck was rolling backwards with the parking brake on. So I pulled the drivers side drum off and it didn't want to play nice for me but once I got it off the wheel cylinder took a shit and it was a nasty mess. So even if your brakes aren't that old parts go bad. I like EBC pads on the front http://www.summitracing.com/parts/eb...ssan/model/d21 but I don't know if your doing it yourself.

That sounds like warped rotors. High spots grab and low spots release. Do you have any pulse in your pedal when you are breaking kinda hard?

I have not noticed any pulses. Going out right now to at least check the front pads and will probably take a look at the back brakes tomorrow.
