The Bobcat T590 is a popular skid-steer loader, known for its durability and versatility. However, some users have experienced issues with the parking brake system, particularly in models where the parking brake seems to fail or is lost completely. This article addresses common reasons behind the loss of parking brakes on the Bobcat T590 and provides troubleshooting steps to help resolve the issue.
Understanding the Issue: Lost Parking Brakes
A lost or non-functional parking brake can pose serious safety concerns, as it prevents the operator from securely locking the machine when not in use. In the case of the Bobcat T590, this issue might be due to several factors, such as faulty components, electrical problems, or mechanical malfunctions.
Common Causes of Parking Brake Loss
A lost parking brake on the Bobcat T590 can be a frustrating issue, but with proper troubleshooting and attention to detail, it can often be resolved. Start by checking the parking brake switch, inspecting the electrical and hydraulic systems, and examining the brake components for wear or damage. Regular maintenance of the parking brake system will help prevent these issues from recurring and ensure the safety and reliability of your machine. If needed, seek the assistance of a professional technician to handle more complex repairs.

In the case of the Bobcat T590, this issue might be due to several factors, such as faulty components, electrical problems, or mechanical malfunctions.
Common Causes of Parking Brake Loss
- Faulty Parking Brake Switch
The parking brake switch is an essential component that activates the brake. If the switch becomes damaged or worn out, it may fail to engage the parking brake system, leading to the brake not holding.
- Electrical Issues
The Bobcat T590 relies on electrical signals to engage the parking brake. If there is an electrical fault, such as a blown fuse or a damaged wire, it may prevent the brake from activating.
- Hydraulic System Problems
On some models, the parking brake is operated by a hydraulic system. A failure in the hydraulic components, such as a leaky line or low hydraulic fluid, could affect the operation of the brake.
- Brake Cable Issues
In mechanical systems, parking brakes are often connected to cables that control the brake mechanism. Over time, these cables may stretch, wear out, or become loose, causing the brake to fail.
- Brake Pad or Drum Wear
As with any brake system, regular wear and tear on the pads or drums can lead to reduced brake performance. If the brake pads or drums on the Bobcat T590 are worn down too much, the parking brake may not function correctly.
- Check the Parking Brake Switch
Inspect the parking brake switch for any visible damage or signs of wear. If the switch appears to be faulty, it may need to be replaced. You can test the switch by using a multimeter to check for continuity when the brake lever is in the engaged position.
- Inspect the Electrical System
Check for any blown fuses, damaged wiring, or corroded connectors that could affect the electrical signals controlling the parking brake. If any issues are found, repair or replace the faulty components. Ensure that the battery is also fully charged and in good condition, as low voltage can also cause electrical issues.
- Examine the Hydraulic System
If the parking brake system is hydraulic, check for leaks in the hydraulic lines and ensure the fluid level is adequate. A drop in hydraulic pressure due to a leak or low fluid could prevent the brake from engaging. Refill or replace any damaged hydraulic components as necessary.
- Inspect the Brake Cables
If the Bobcat T590 has a mechanical parking brake system, inspect the brake cables for any signs of stretching or damage. If the cables appear loose or worn out, adjust or replace them. A loose or improperly adjusted cable can prevent the parking brake from fully engaging.
- Examine Brake Pads and Drums
Inspect the brake pads and drums for excessive wear. If the pads are worn down or the drums are damaged, replacing these components will likely resolve the issue. Be sure to follow the manufacturer's specifications for parts and installation.
- Check the User Manual
Always refer to the Bobcat T590 user manual for specific instructions on troubleshooting and maintenance. The manual provides detailed information on the brake system, including troubleshooting tips and part numbers.
- Consult a Professional Technician
If troubleshooting and repairing the parking brake system yourself does not solve the issue, it may be time to consult a professional technician. A qualified technician can diagnose more complex issues, such as electrical system failures or hydraulic malfunctions.
