Welcome to Rolon Mobile Truck Repair, your go-to provider for all semi-trailer brake repair needs. We understand the vital role that brakes play in the safety and functionality of your semi-trailer. Our services are designed to keep your trailer in optimal condition, focusing on the thorough maintenance and repair of the entire trailer brake system, both air and foundation components.

Why are Trailer Brake Systems Important?

Trailer brakes are essential for ensuring the safety of heavy vehicles. Air brakes use compressed air, providing greater stopping power and reliability for large loads. This system includes critical components like valves and chambers, along with foundation brakes (drums, shoes) that apply the stopping force. A properly functioning semi-trailer brake system, including its interface with the trailer's electrical system for lights and ABS, is crucial for control and meeting safety regulations.

Your Semi-Trailer Brakes System Questions, Answered

We get many questions about semi-trailer brakes. Here are some of the most common ones, with our answers:
1. How do you adjust semi-trailer brakes?
Adjusting trailer brakes on a semi typically involves turning the S-cam mechanism via the slack adjuster until the brake shoes make contact with the drum, then backing it off slightly (usually 1/4 to 1/2 turn). This is a safety-critical procedure best performed by a qualified technician during brake maintenance.
2. How do you replace trailer brakes?
Replacing trailer drum brakes involves removing the wheel and drum, then disassembling the old hardware (springs, rollers) and brake shoes. New shoes and hardware are installed, the drum is replaced (or machined if possible), and the brakes are properly adjusted. This requires specialized tools and expertise.
3. How do you adjust trailer drum brakes?
Adjustment is done using the slack adjuster, which rotates the S-cam to push the brake shoes closer to the brake drum as they wear. Proper adjustment ensures minimal delay when applying the brakes. Automatic slack adjusters should maintain this, but manual ones require periodic checks.
4. How do you unlock trailer brakes?
If semi-trailer brakes are locking up due to loss of air pressure (emergency application), you need to supply air to the red gladhand (emergency line) using the tractor or an external source. If a spring brake chamber has mechanically failed, a technician may need to "cage" the brake manually using a caging bolt to release it for movement.
5. Why are my semi-trailer brakes locking up?
Brakes locking up can be caused by several issues: loss of air pressure in the emergency line, a malfunctioning relay or emergency valve, frozen air lines in cold weather, or mechanical failure within a spring brake chamber. Immediate diagnosis by a professional is required.
