Rotors

[billybos]

What’s up have 50,000 miles on the ranger and I need to change my rear brake pads. Question is do I have to change the rotors. To me I would say no but some people say the rotors do not last as long as they used to I do not see any visual problems other then normal wear I would just like to get some of you guys opinion

If you want to do it right, yes. You're living in the rust belt, just like me. Those rotors are going to be shot.

The best way to know is measure. You can find the service instructions on this forum, they will provide rotor specifications.

50k and already shot? I'm at 120k and still got some life left.

Replaced my rear pads and rotors at 32k. But I drive up and down, never level.

Yeap same.... I use mine for Uber/lyft and to visit my customers

Would only replace rotors if out of tolerance (unlikely at 50k), deep gouges, pulsing, hot spots. Not just because of a pad change

Save yourself the money, it does not "need" to be done. If you experience something like the above, by all means

Still waiting for mine to need a change at 150K miles...soon...

While to do it right can have some shortcuts implemented if using the old rotors, it mainly depends on if you were having (pulsating pedal) issues or vibration issues when braking.

The decision is based on what does the rotor surface look like and what do the off pads look like
If there are any indications of (Hot Spots) or (Cracks) replace the rotors

Don't just slap on the new pads and call it good:
Take the extra steps - remove the rotor and scuff it up - take the glaze off of it. I personally use the (Yellow -Roloc) Disc - it's great for rotors and do not forget to clean the rotor hat and hub surfaces and of course clean and lube the caliper guide pins

Keynote: As this is the Rear Pads, you should be aware that the rear calipers have the parking brake pistons and they do not compress in, they screw in with a special winding tool and there are a number of threads on how to do it on here.
Note that pads are side specific - which is detailed in that thread, I would have to locate it

If you wanted to take an extra step - you could use a hand mic around the rotor to ensure you are in specs for DVT (Disc Variation Thickness)

Ditto on what airline said.

Me personally, i always resurface them if i am able too.

Just my FYI regarding my experience with the rear brakes...
Fun at 7000 miles...

Two years later...

My left inner pad died and ripped up the rotor as well..Irellaced all 4 corners with R1 Concepts Front and Rear Brake Kit, Drilled Slotted Brake Rotors| Optimum OEP Brake Pads

Also lube your caliper slides

 

[jflogerzi]

oem is going to be best
