Understanding Brake Pad Materials
When replacing brake pads, it's crucial to understand the differences between organic, sintered, and semi-metallic pads. Sintered brake pads, like the EBC FA 447 HH used in this guide, are ideal for sport bikes due to their longer wear time and superior performance in high-heat applications and wet conditions. However, they take a while to warm up and can be noisier than organic pads. Organic pads, infused with rubber, are quieter but wear out faster. Semi-metallic pads, prone to glazing and heat failure, are not as reliable.
Step-by-Step Brake Pad Replacement
1. Preparation: Before removing the caliper bolts, take off the cap of the brake fluid reservoir to facilitate the easy depression of the pistons.
2. Remove the Old Pads: Use a 12mm socket to remove the caliper bolts. Depress the pistons with a large flathead screwdriver, then remove the old brake pads by sliding them out.
3. Install New Pads: Insert the new sintered brake pads with the shiny side toward the piston. Ensure they fit snugly into the caliper.
4. Reassemble and Torque: Slide the caliper back over the rotor and torque the bolts to 28 foot-lbs using a torque wrench.
Changing the Brake Fluid
1. Drain Old Fluid: With the new brake pads installed, it's time to flush out the old brake fluid. Use an 8mm wrench and a vacuum bleeder to remove air and old fluid from the lines. Attach the vacuum bleeder to the bleeder screw and the brake lever.
2. Bleeding the Brakes: Pump the brake lever to build pressure, then open the bleeder screw to allow the old fluid and air to escape. Keep an eye on the reservoir to prevent it from emptying completely and introducing air into the system.
3. Add Fresh Fluid: Refill the reservoir with fresh DOT 4 brake fluid. Repeat the bleeding process until the fluid in the vacuum line is clear and free of air bubbles.
4. Final Steps: Clean any spilled brake fluid with a degreaser or warm water, top off the reservoir, and ensure the cap is secure. This keeps moisture out and maintains brake performance.
By following these steps, you can ensure your motorcycle's braking system is in top condition, providing safe and reliable performance for your rides. Remember to perform brake maintenance regularly to keep your bike running smoothly and safely.
