One of the most common repairs you’ll see on your car is a resurfacing of the rotor. Rotors are essentially the discs that turn as the car brakes. They can become damaged over time, and over time, the metal disc can start to rust. This rust can cause problems with the braking system, so it’s important to get it fixed as soon as possible. However, many people don’t know how to do this themselves. That’s where sandpaper comes in. Sandpaper is a simple tool that can be used to repair rotors quickly and easily. By removing the rust and corrosion, you can restore the rotor to its original condition. Here are some tips on how to resurface rotors with sandpaper:
Materials Required
Materials Required:
-Sandpaper (120, 220, or 320 grits)
-Ruler or a straight edge
-Paintbrush or stiff brush
-Rotary tool with sanding pad
-Sponge or cloth
-Water bottle
1. Start by measuring the circumference of each rotor on the bike. This will help you determine which grit of sandpaper to use.
2. Place the ruler on the rotor and measure from one edge to the other. Write this measurement down.
3. Place the sandpaper on your work surface and draw a circle around the measurement you made in step 2. The radius of this circle will be how wide you want your sanding to be. [Note: If your bike has uneven rotors, it’s best to round them off instead of trying to get them perfectly circular]
4. Starting at one edge of the circle, begin sanding away at the rotor with a moderate amount of pressure and continued moving towards the other edge of the circle until it is completely smooth. Be careful not to overdo it or you’ll remove too much material and have to start over again!
5. Once all of the rotors have been sanded, it’s time for finishing touches! Use a clean paintbrush or stiff brush to apply a light coat of sealant or wax to each section that has been sanded and polished. Allow it to dry before riding your bike!
The Process
If you have a car with rotors that are in need of resurfacing, the process is pretty straightforward. Start by removing the old rotor by breaking it off at the hub. This can be done with a hammer and chisel or a vise and a wrench. Once the old rotor is removed, clean up any sanding dust that has accumulated on the rotor surface using a cloth or a shop vacuum. Sandpaper can then be used to smooth out any rough spots on the rotor surface. Be sure to use enough sandpaper to produce a smooth finish but not so much that the paint is scratched or damaged. Finally, apply a layer of sealant to the surface of the rotor and screw it back into place.
Tips for Success
1. Start by lightly sanding the rotors with medium-grit sandpaper. Be careful not to over sand the surface, or you will remove too much material and end up with a rough finish.
2. Use a finer grit if necessary to achieve a smooth finish.
3. After sanding, rinse the rotors with water and dry them off completely before applying an anti-glare coating or sealant
