3M 7000120356 Brake Rotor Conditioning Disc 120 Grit 12 Pack

Product Description

The 3M 7000120356 is a refill pack of Roloc Brake Rotor Surface Conditioning Discs engineered to create a non-directional scratch pattern on brake rotor surfaces after turning. Each disc mounts via the Roloc quick-change attachment system, allowing fast disc swaps without tools. The pack contains twelve 120-grit discs, providing enough material for multiple rotor service jobs. This abrasive is used after a lathe pass to condition the rotor face prior to burnishing new pads, helping promote even pad seating and reduce initial brake noise. Installation and use are performed by automotive service technicians.

These discs are suited for brake rotor reconditioning in automotive and light-truck service applications. After a rotor is turned on a brake lathe, the surface requires a non-directional finish to meet OEM brake break-in specifications. The 7000120356 refill pack is designed for shop environments where the Roloc disc holder is already in use, keeping consumable costs predictable. Typical users include automotive technicians and brake specialists performing routine brake service on passenger vehicles and light commercial vehicles.
