Why do I have rust on my brake rotors?

Why do I have rust on my brake rotors?

The popularity of alloy wheels puts brake rotors on full display. Rotors, however, must be made from heavy, heat-resistant, metal—unprotected metal that easily rusts* under the harsh conditions of a wheel well. The unsightly discoloration showing through their expensive alloy wheels leads many people to ask how to remove rust from brake rotors.

How do you get rust penetrant off a rotor?

Rotate the rotor 180° and repeat until the rust penetrant is dripping off the bottom of the rotor. Tap around the rotor hat with a hammer to set up vibrations to work the rust penetrant in deeper.

What should I do if my brake rotor is stuck?

Do NOT crank down on the bolts or you’ll strip the threads. Then, with slight pressure from the bolts pushing against the wheel hub, smack the rotor face around its outer edge. Do this several times, then tighten the bolts ¼ turn and repeat. Continue smacking and tightening until the rotor breaks loose.

Can a lug nut be torqued to remove rust?

And, the lug nuts should be torqued only after the vehicle is down off the jacks. Because removing rust from rotors is a cosmetic exercise (normal use of the vehicle keeps it in check), painting the hub will improve the appearance and prevent the non-braking surface of the rotors from becoming unsightly.

What should I use to remove a stuck brake rotor?

Most often these holes use a metric thread, so you’ll need metric bolts. Here’s how to proceed with the removal. • shoot rust penetrant (Liquid Wrench, PB Blaster, etc ) between the studs and the rotor. Rotate the rotor 180° and repeat until the rust penetrant is dripping off the bottom of the rotor.

Can You Leave your brake rotors out in the rain?

Even so, brakes can work quite well according to my experience with some reduction in swept area but don’t let this go too long. You can leave brake rotors out in the rain for years and they will never “rust out”.
