The process of restoring a brake disc’s surface to a smooth, even condition is a common procedure in automotive maintenance. This involves removing a thin layer of material from the rotor’s surface using specialized equipment, effectively eliminating imperfections such as grooves, rust, or scoring. An example of when this might be necessary is when brake pedal pulsation is experienced during braking.
Undertaking this maintenance provides several advantages. It can extend the lifespan of brake pads, improve braking performance by ensuring optimal contact between the pad and the rotor, and reduce brake noise. Historically, it has been a cost-effective alternative to complete rotor replacement, offering a more economical repair option. It also reduces the amount of metal that ends up in landfills, compared to simply replacing the brake components with new parts.
