Using this brake caliper spacer shim is easy. First, make sure you have a 12mm wide brake disc and either a 1375B or 181375 brake caliper. Don't try to use it with the MCP 1384 - SE Single Line Internal Crossover Style Brake Caliper as it won't work. The brake caliper needs to be bought separately. To maintain it, just keep it clean and dry. Regularly check for any signs of wear and tear. If you notice any issues, replace it right away to ensure your braking system works well.
