Maintaining the brake system of truck-mounted cranes during winter is of paramount importance. The proper upkeep of the brake system is directly linked to the safety of the driver. The maintenance of the brake system primarily centers around the care of brake pads and brake fluid. Now, let’s explore with the editor how to conduct inspections and maintenance on brake pads and brake fluid.
Irrespective of the type of brake system employed, whether it’s disc-based or drum-based, the ultimate braking effect is achieved through the interaction of brake pads (in the case of disc brakes) or brake shoes (in the case of drum brakes). Consequently, it is essential to regularly inspect the thickness of the brake pads or brake shoes. When it is observed that their thickness approaches or falls below the minimum stipulated by the manufacturer, immediate replacement is imperative.
Let’s delve deeper into this aspect. The brake pads or shoes are subjected to significant friction and wear during braking operations. Over time, their thickness gradually reduces, and if not replaced in a timely manner, it can compromise the braking efficiency and safety. Insufficient thickness can lead to longer braking distances, reduced braking force, and potential failure in critical situations.
During the inspection of the brake pads, it is equally important to assess the wear on the brake discs or drums. If any indentations or unevenness are detected on the contact surface, it is necessary to have the discs or drums resurfaced promptly. This ensures a larger and uniform contact area with the brake pads, thereby enhancing the braking force and overall braking performance.
Uneven or damaged contact surfaces can result in inconsistent braking, increased vibration during braking, and accelerated wear of the brake pads. Resurfacing helps restore a smooth and flat surface, optimizing the transfer of force and heat during braking.
Inspection of Brake Fluid of Truck-Mounted Cranes
Before initiating the inspection of the brake fluid, it is crucial to meticulously wipe off any dirt or debris accumulated on the master cylinder. This precaution is to prevent any dirt from falling into the reservoir and contaminating the fluid. Remove the fasteners (typically pins) and the cover. For master cylinders without graduated scales, the liquid level should be maintained approximately 6 mm from the top of the cylinder. In cases where graduated scales are present, ensure that the liquid level remains higher than the indicated minimum.
If a decrease in the oil level is noticed, an immediate and thorough check for leaks in the brake oil circuit is necessary. Any leak in the system can lead to a loss of braking pressure and pose a serious safety hazard. If the brake fluid appears dirty or contaminated, it is essential to drain and flush the entire system thoroughly. Subsequently, refill the master cylinder with fresh and clean fluid.
It is important to note that reused brake fluid is not recommended. All the drained brake fluid from the system should be disposed of properly. Special caution must be exercised to avoid spilling the brake fluid on the vehicle’s paintwork as it is highly corrosive and can cause significant damage to the topcoat.
Over an extended period, if the brake fluid is consistently depleting and requires frequent topping up, it is a clear indication that there might be an underlying issue with the brake system that demands immediate inspection and rectification.
The brake fluid has the tendency to deteriorate over time due to its absorption of moisture from the surrounding air. In accordance with the manufacturer’s guidelines, the brake fluid should be replaced at regular intervals, preferably once a year. Clean and high-quality brake fluid forms the foundation for a safe and efficient brake system. It is advisable to invest in the best-quality brake fluid available in the market.
Among the various maintenance tasks associated with the brake system, the regular checking of the brake fluid level holds the greatest significance. At a minimum, this check should be conducted once a month, and more frequent inspections are even better.
The color of the brake fluid can also serve as an indicator of potential problems. If the color of the brake fluid becomes overly dark or shows signs of discoloration, it could suggest the presence of impurities or degradation, indicating a need for immediate attention and possible replacement.
The diligent inspection and timely replacement or maintenance of brake pads and brake fluid are crucial for ensuring the seamless operation of the brake system and averting any unforeseen malfunctions.
A well-maintained brake system not only enhances the safety of the vehicle but also contributes to a smooth and reliable driving experience. By adhering to these maintenance practices, truck-mounted crane owners can safeguard their vehicles and minimize the risk of brake-related issues, especially during the challenging winter conditions when reliable braking is of utmost importance.
In conclusion, giving due attention and care to the brake system’s maintenance, particularly during winter, is an essential aspect of vehicle upkeep that should not be overlooked or underestimated.
