Resurfacing Your Rotors
Sometimes your rotors may need to be resurfaced because they have worn unevenly, warped from heat, or become damaged by worn brake pads or pitted from corrosion or rust
. Resurfacing rotors removes some of their metal, until the surface is smooth and even again.
Can you resurface a brake pad?
If the brake discs are still smooth they may not need to be resurfaced, but
most professional brake mechanics will not install new brake pads without resurfacing the rotors
. Resurfacing restores a flat and even surface that minimizes vibrations and allows for maximum brake pad friction.
Can brake discs be resurfaced?
Resurfacing Your Rotors

Can you sand disk brake pads?
For the brake pads,
you will only need to remove them from the caliper, and give them a light sanding with fine grit sandpaper
, just enough to remove the shiny glaze from the surface of the pad. After a while, pads can become crystallized and glaze over, this causes brake squeal and a notable decrease in braking power.
How do you resurface brake pads on a mountain bike?
Can I use white spirit to clean brake discs?

. The material will absorb it and as you’ve discovered, it will have a detrimental effect.
Is rotor resurfacing bad?
A resurfaced rotor must meet the minimum thickness specification defined by the rotor manufacturer.
If a rotor can’t meet the minimum thickness, you shouldn’t resurface it as it’ll become too thin, unsafe, and warp easily
. Next, the rotor mustn’t be warped or cracked. Always get a new rotor for this type of damage.
Is it better to buy new rotors or resurface?
In the long run, it’s likely less expensive to replace your rotors when there are consistencies in the face of the rotor. New rotors won’t wear as quickly on your brake pads as damaged rotors, and
resurfacing the rotors means you’ll only get one last “hoorah” out of them before they need to be replaced anyway
.
Can you resurface brake rotors at home?
Can you fix glazed brake pads?
Glazed Brakes
When the pads glaze over it is a microscopic change to the friction material on the very surface of the pad caused by heat. The Fix:
The best fix for this one is to change your behavior and not ride the brake in stop and go traffic
.
Can I put new brake pads on old rotors?
Having a fresh rotor for the new brake pad to grab onto means the driver will experience optimal braking performance. If the old rotors are kept on the vehicle, you run the risk of the pads wearing improperly. This can lead to the premature replacement of the brake pads which will be costly for the customer.
How much does resurfacing rotors cost?

.
Is brake cleaner isopropyl alcohol?
It’s just alcohol that is used for cleaning medical equipment
and things like that, it’s about 99.9% pure. Personally I always just use brake cleaner on my bike rotors.
Are rotor resurfacing worth it?
Those severely damaged rotors usually need to be replaced, not resurfaced
. Some vehicle manufacturers even require that you replace your rotors rather than resurface them. Otherwise, most industry experts suggest that you should replace them every 30-70K miles.
How long does resurfacing rotors last?

If they aren’t damaged or thinned beyond the discard thickness, you can definitely change just the worn brake pads
. What’s discard thickness? It’s the minimum thickness for rotors, as specified by the rotor or vehicle manufacturer.
