One of the bike’s most critical components is the brakes. The brakes’ qualities, traits, and behavior are essential for a two-wheeler to be kept in proper condition over the long haul. These are controlled by temperature, operation patterns, durations, and efficient interconnections. Examining the brakes when purchasing a used bike is crucial to ensuring that the bike is in proper shape. The other parts can be repaired and adjusted to address many brake-related problems.
7 Most Common Motorcycle Brake Problems and Solutions
1. Brake Fade
Brake fade, which occurs when the brakes fail frequently, keeps the wheels on the ground for an extended period. The friction behavior of the brake varies with temperature and becomes more problematic as temperature rises. It is a result of the bike’s prolonged use without adequate maintenance. Bike servicing is essential for all these things to be taken care of promptly.
When the brakes are applied forcefully as a result of the expansion of the brake drums, brake fade occurs. This results in a reduction in the frictional properties of the brake lining or both. It would help if you used lower gears, and the speed must be decreased. Once the fade disappears, the brake’s efficiency is fully recovered.
The brake lining and drum may not make proper contact due to the brake fade. Most of us have a nasty habit of dragging the brake, which makes it heat up excessively and creates a brake fade. The rider should not maintain his foot on the brake pedal or hold the brake lever depressed when necessary.
2. Brake Binding
Due to the bike brake’s condition, the liner frequently sticks to the drum. Brake lever remnants are applied without pulling the lever. It’s sometimes referred to as brake dragging. Defective springs are one of the main causes of brake binding. The pedal return spring or the springs that retract the brake shoes may be worn out or broken. This device needs to be replaced almost immediately.
The brake shoes stuck over the anchor pins are another critical factor. Lubricating this anchor pin can resolve the brake binding. The fluid level in the reservoir of these disc brakes may be too high, which needs to be fixed to reduce brake binding.
3. Brake Overheating
In most cases, the same factors that cause the brakes to overheat also cause the brakes to bind. The binding risks increase when the bike brake’s friction qualities are reduced by overheating. After using the brakes for an extended period while descending a slope, other factors could arise.
In addition to that, the piston in the caliper may also seize in such circumstances. In this case, it will change the piston, and the caliper will be rebored.
4. Brake Judder
Suppose you heard a ringing noise from the brake. Either the brakes are not adjusted properly, or the brake lining rivets may need to be tightened. In such circumstances, new rivets must be used to reattach the linings. Additionally, the linings require replacement.
5. Grabbing Brakes
The brake is either seized or tends to become seized when it is grasping. In these situations, smooth linings are frequently damaged by drum brakes. Workers may neglect to clean the clippers before assembly, which causes them to grip after some use. Brake grabbing is frequently a factor in incorrect shoe adjustments. Brakes are grabbed as a result of a scouring brake drum. Occasionally, it can be stopped by grounding the drum within certain bounds.
Your brake shoe assembly may have dirt or dust; therefore, you must clean it promptly to stop the brakes from gripping. A rather peculiar purpose exists for grabbing the switched shoes. By accident, the primary and secondary shoes have been switched. If the shoes are correctly reinstalled, the brake gripping will stop.
6. Excessive Fluid Leak From The Brakes
It primarily concerns oil leaks from the disc brake system, as the name implies. The joints, caliper, plunger assembly, or reservoir could all leak, as well as benzo bolts. If the brake oil leak is not regulated, it will diminish braking efficiency and increase maintenance costs.
The reservoir and caliper are where the major leaks occur. It is examined, and if necessary, repairs are made. Another factor contributing to brake fluid loss is sloppy connections at different joints. To prevent future fluid loss, the damaged hose or pipe needs to be thoroughly inspected and replaced as soon as possible.
7. The Brake Line Contains Air
The disc brake unit is particularly affected by the flaws. Only because incompressible brake lubricants are used to operate the disc brake. An incompressible oil connects the piston and lever of the caliper. It is a clever method for amplifying the brake lever force, which also applies to the caliper piston.
The viscosity of the brake oil is necessary for this function. Even a small amount of air entering the brake line can cause the entire system to fail, as the air is compressible in the fluid. The air still contains bubbles and compresses the brakes, reducing their effectiveness.
The only thing that can cause air bubbles in brake lines is leaks. Flaws in the reservoir or caliper that let air into the system. You must promptly fix the leak and, if necessary, replace it. You can properly tighten any loose connections to prevent air bubbles from forming. When brakes are bleeding with air bubbles, there are secure solutions. It is a must to maintain a real service station.
To put it simply, having a reliable braking system is essential for the bike. If you purchase a used bike, you should inspect the brakes before riding it.
