HOW TO REPAIR THE DISK BRAKE MOTORCYCLE SYSTEM?

HOW TO REPAIR THE SYSTEM?

any motorcyclist knows, a motorcycle must not only go fast, but also stop stably. If a motorcycle just runs fast and can't stop as you want to, you're joking with your life! Now the motorcycles have mostly used the custom motorcycle brake discs, because the effect of the disc brake is relatively better, but the structure is more complex than the drum brake system before. Therefore, the is very important. Today, Jumpo shares some relevant knowledge points and encourages everyone.

Let's talk about the brake fluid first. It is an important transmission medium in the whole system of motorcycle brake accessories. If the brake fluid is not properly selected, the brake system may fail unexpectedly and cause dangers due to braking delays. Brake fluid is also called brake oil, which can be divided into alcohol brake fluid, synthetic brake fluid and mineral oil brake fluid according to its raw materials, process and use requirements.

Synthetic brake fluids and mineral oil-based brake fluids are mostly used in automobiles, and alcohol-based brake fluids are mostly used in motorcycles. Brake fluid has the characteristics of low freezing point, good low temperature fluidity, high boiling point, no bubbles at high temperature, good chemical stability, and no corrosion of metal parts and rubber parts of the brake system. The biggest disadvantage of alcohol-based brake fluid is that it is easy to absorb water, resulting in a lower boiling point. In this way, many air bubbles will be generated in the system during braking, which will reduce the braking force and cause safety hazards to the driver. Therefore, under normal circumstances, the brake fluid should be replaced every two years, and the brake fluid that has been opened and left for a long time is not recommended to be used again. The motorcycle brake maintenance focuses on three words, namely "look", "try" and "discharge".

Disk Brake Parts for Motorcycle Brake Maintenance: Look

It means checking the appearance. 1) Check if the brake fluid leaks. If it leaks, wipe up the leakage first and check if the leakage is serious. Timely go to the repair shop to find out the cause and repair it in this situation. 2) Check if there is sediment at the brake calipers. If there is sediment, clean it first to prevent that the brake cylinder and friction disc do not return, which can influence the braking effect and braking system life. 3) Check the brake fluid. If the liquid level is lower than the minimum line, an appropriate amount of brake fluid of the same specifications should be added to the top notch line; if the color is discolored or cloudy, the brake fluid is aging and needs to be replaced. 4) Check the motorcycle disc brake. When the motorcycle disc brakes are worn to the marked line, they should be replaced in pairs.

Disk Brake Parts for Motorcycle Brake Maintenance:Try

Grab the brake handle, and the disc brake should respond quickly. If you feel that the braking action is not crisp but spongy, and the disc plate cannot clamp brake disc, it shows that the air enters the brake system into the air, reducing the brake effect.

Disk Brake Parts for Motorcycle Brake Maintenance: Exhaust

It is a dangerous situation that the air enters the motorcycle brake braking system, which may lead to accidents due to brake failure. There are many reasons for the entrance of air into the brake system pipeline, for example, the sealing of the pipeline is poor, the aerothermal gasification produces gas resistance, the alcohol brake fluid absorbs water, etc. If the air enters the motorcycle brake braking system, you need a repairman to remove air in time. Or you can refer to a post written some time ago to discharge the air.

The assembly of a disc brake for motorcycles involves several key components. The main parts include the brake caliper, brake pads, brake rotor (disc), and mounting hardware. The caliper holds the brake pads and applies pressure to the rotor, creating friction to slow down or stop the motorcycle. When it comes to , it's essential to inspect and maintain these components regularly. This involves checking the brake pads for wear, ensuring proper caliper operation, and inspecting the brake rotor for any damage or warping. If any components are worn or damaged, they should be replaced promptly to maintain optimal braking performance and rider safety.

FAQs about Repairing

How To Remove Air From Motorcycle Disk Brake

To remove air from motorcycle disc brakes, you can follow a process called "bleeding." Start by locating the brake caliper bleeder valve, typically found on the caliper itself. With a brake bleeding kit or a clear tube attached to the bleeder valve, open the valve and pump the brake lever or pedal to force out the air bubbles. Maintain fluid pressure while closing the valve, ensuring no air is sucked back in. Repeat the process until all air is purged, ensuring a firm brake lever or pedal feel.

How To Change Motorcycle Brake Discs

To change , begin by lifting and securing the bike. Remove the brake caliper bolts, allowing the caliper to swing away from the disc. Next, detach the old brake disc by unscrewing the mounting bolts. Clean the hub surface and install the new brake disc, aligning the holes properly. Tighten the mounting bolts evenly, ensuring secure attachment. Finally, reattach the brake caliper and test the brakes before riding. Refer to the motorcycle's service manual for specific instructions and torque specifications.

How To Adjust Disk Brakes On A Motorcycle

To adjust disc brakes on a motorcycle, start by checking the brake lever or pedal for excessive travel. If there is too much play, locate the brake caliper adjustment knob or bolt. Turn the knob or bolt in small increments clockwise to tighten the brake pads against the disc until the desired lever or pedal feel is achieved. Avoid overtightening, as it may cause brake drag. Additionally, ensure the caliper is properly aligned with the disc, and the brake pads have sufficient material. Adjustments may vary depending on the motorcycle model, so consult the owner's manual for specific instructions.

Why Are My Motorcycle Disc Brakes Not Working?

Several factors can cause motorcycle disc brakes to not work effectively. Potential reasons include worn-out brake pads, insufficient brake fluid, air in the brake system, damaged brake lines, or malfunctioning calipers. Check the brake pads for wear, ensuring they have enough thickness. Verify the brake fluid level and condition, topping it up or replacing it if necessary. Bleed the brakes to remove any trapped air. Inspect the brake lines for leaks or damage. If the issue persists, consider seeking professional assistance to diagnose and address the problem properly.

How Do You Fix Disc Brakes Rubbing On A Motorcycle?

If your motorcycle's disc brakes are rubbing, there are a few steps you can take to fix the issue. Start by checking the brake caliper alignment and ensuring it is centered on the disc. If it is misaligned, adjust the caliper position using the mounting bolts until it is properly aligned. Additionally, check the brake pads for wear and replace them if necessary. Inspect the rotor for any warping or damage. If the problem persists, seek professional assistance to further diagnose and resolve the rubbing issue to ensure proper brake performance and safety.
