But; I needed to store the frame outside for a couple years. Now that I have the motor close to done I want to finish up the frame work. My brand new font disc brakes and rotors look 20 years old. They are sooooo rusted. Any way to clean them up or is it money lost and start over?? | | | | | Joined: Feb 2004 Posts: 29,805 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,805 | Use a ScotchBrite Roloc disc in a drill motor to polish the rust away. The 3" size works best for brake rotors. There are plenty of them on Ebay.

You will then be able to see if you have pitting. Driving the truck will clean them up better than anything else if you find that they aren't pitted.

A slightly pitted rotor won't seriously reduce braking ability. A too-thin one will heat up and be very inefficient.
