Cubitron Scotch-Brite Roloc Pro Brake Hub Cleaning Disc, XO-DR, 07546, SiC Extra Coarse, 1-1/2 in x 5/8 in

These work great and I am able to get around each stud to fully remove the rust and then go between the studs. I still need a wire wheel for the areas too close to the stud next to the center protruding ring where this cannot quite reach as it touches the stud and the ring and leaves a small triangle shape. A little rust build up can move the rotor enough to give pulsing brakes and I hate that. Now I can remove the rust, give a light coat of grease and install the rotor knowing I won't have rust build up messing up my new brake job.

I saw these used on South Main Auto's channel on YouTube. They work great getting rid of rust right where it's critical near the studs on the hub. If you're changing your rotors you must have a clean flat surface and these get the job done nicely. Make sure to get the adapter for your cordless drill these are just the scrubby ends. Highly recommend these for any DIYer or professional. They're made by 3M so quality is top notch.

Loved this product! Used to buy small packs from autozone and such but a 10 pack for this pricr!? Can't complain! Used it to clean hubs, when replacing wheel bearings, and so much more!

Package contains 10 roloc discs but not the pictured adapter. Part number 21713 is on the box. The instructions in the box talk about the holder and discs as in photo

Exactly as described. Came in 3M packaging containing 10 pieces.

These discs are one of my "go to" tools for metal finishing/cleaning/smoothing. Unlike grinder wheels, these will leave a beautifully smooth surface. Perfect for cleaning mating surfaces and removing old sealant/gasket material. Be careful though as they are designed to remove metal they can also damage your mating surface if you are too aggressive. Love this product and will continue to rely on it!

Expected from a 3M product. Pleased with purchase.

These discs, plus their holder make cleaning corrosion around lug studs a snap!
