Rear Brake Rotor

Claviger said:

For the lateral movement of the friction portion of the rotor across the buttons, there should be a few mm of play. There should be zero movement on the carrier portion, the middle part that's bolted to the wheel.

Typically the problem on free floating rotors is they get tight and stop moving at the button area, this usually leads to a pulsing at the lever/pedal, similar to a warped rotor.

when i worked on tribals 2005 front rotors 200000+ they had a lot of play but did not give problems we replaced because the brake pads wore out the rotor
with him towing that trailer put a lot of wear on the system.
yes i know we are talking about a different set up but we are still talking about a floating system.

If you check, I think you can purchase replacement floating brake rotor buttons. This might be a cheap solution if the buttons were the worn part causing the play. There are a number of videos showing how to replace.

Something I just came across while looking for a video on cleaning up calipers (I've often shared) that seems related to this post. This one is about rotors. Never done it, but will be shortly, especially after reading of other's problems with rotors...
