I searched rockauto and found these, can someone verify that these are the what I need.
More Information for RAYBESTOS RC11885

Do I need them with or without center rattle clip?

 

during my parts search for rear breaks, i find alot that says 4wd only. i didn't see in this thread clearly if i need to look for the 2wd or 4wd break setup. can anybody clear this up for me?

 

2WD 05+.

The AWD or 4 wheel disc used a smaller front rotor and different pad.

 

im actually asking about the rear setup.

 

You just need to use the correct Rotor and pads with the dual piston calipers.

There are 2 different rotor thickness. 28mm and 31 or 32mm

 

are you saying the caliper won't matter (2 piston) just make sure the pads match the rotor?

 

Hello,

I found this thread a few months ago...been a forum reader for a while. My 2000 silverado was due for a complete rear brake overhaul so I went with what I read here. I decided to replace the backing plate too as mine was about half it's original size due to rust.

I ordered '05 tahoe z71 parts - rotors, pads, calipers and brackets. The job went smooth with no problems. Everything looks good as well. One thing I noticed since this upgrade is that my front brakes have become prone to locking up much easier than with the original setup. It seems like the fronts are stopping more of the vehicle than before which is causing the abs to kick in under a hard stop. The rear are working. I could see they were when I was bleeding them but I'm guessing just not as much, maybe? I'm stumped but I'm not a mechanic so I thought I'd post.

Has anyone that did this upgrade on a 2000, or year close, noticed this? I looked up master cylinders and the Tahoe shows a different part number than a 2000 1500. Any input on this is appreciated.

Thank you,
Joe

 

You may need to get an adjustable proportioning valve or a distribution block for a Tahoe Joe.

If it was designed with drums or smaller rear discs it would send less fluid to the rear...increase the requirement for fluid but still send less and you end up with what you are getting. The original distribution block may be limiting your rear brakes.

Just a thought.

 

That's what I was thinking. I looked up a few adjustables last week. I'm going to see if anyone else chimes in with this issue then move forward with the prop valve. I would think others that did this would of run into the same problem. Also, I swear I read a thread on this "upgrade" and one poster said the prop valves were all the same.

 

I have 05 tahoe brakes on the rear and 05 truck brakes on the front of my 99. I also have the abs disabled so the brakes are less...forgiving. I have noticed it seems like the rears actually do more work than I think they should. Havent looked too far into it because the stopping power is great, but it does make doing a burnout difficult.
