If you feel that the rear wheel brake on your Yamaha FZ S V2.0 with a rear disc brake is not as effective as the drum brake model, there are a few steps you can take to potentially improve its performance. Keep in mind that it's important to ensure your modifications are within legal limits and won't compromise safety. Here are some suggestions:
Brake Pad Inspection and Replacement: Check the condition of the brake pads. Worn-out or damaged brake pads can reduce braking performance. If they are significantly worn, replace them with high-quality brake pads recommended for your motorcycle model.
Brake Fluid Check and Bleeding: Ensure that the brake fluid level is adequate and the fluid is in good condition. If the brake fluid hasn't been changed for a long time, it may be worth considering bleeding the brake system to remove any air bubbles or contaminants that could be affecting brake performance. Consult the owner's manual or seek professional assistance for this procedure.
Rotor Inspection and Cleaning: Inspect the rear brake rotor for any signs of excessive wear or damage. Clean the rotor surface using brake cleaner to remove any contaminants or debris that could be affecting braking efficiency.
Caliper Maintenance: Check the caliper for any signs of sticking or uneven movement. Ensure that the caliper slides freely and is properly lubricated. If necessary, clean and lubricate the caliper pins or seek professional assistance to ensure proper functioning.
Adjust Brake Lever and Pedal: Ensure that the brake lever or pedal is adjusted correctly for your riding style and preference. There should be sufficient free play before the brake engages, but not too much to reduce response. Refer to the owner's manual for instructions on adjusting the brake lever or pedal.
Tire Condition: Check the condition and inflation of your rear tire. Worn or improperly inflated tires can affect braking performance. Ensure that your tire is in good condition and properly inflated according to the manufacturer's recommendations.
Professional Inspection: If you have tried the above steps and still feel unsatisfied with the rear brake performance, it may be beneficial to have a professional mechanic inspect your braking system. They can identify any specific issues and recommend appropriate solutions.
Remember, modifying the brake system of your motorcycle should be done carefully and responsibly. It's always advisable to consult your local authorized service center or a qualified mechanic for expert advice and assistance to ensure the modifications are done safely and effectively.
