If you own a Scamp trailer or are considering purchasing one, understanding common brake problems and their solutions is essential for safe towing. This list covers typical issues with Scamp trailer brakes, including electrical faults, mechanical wear, and maintenance tips. Whether you’re a new owner or a seasoned RVer, these insights will help you keep your trailer’s braking system in top shape.
Electric Brake Controller Malfunction
Many Scamp trailers use electric drum brakes controlled via an in-cab electric brake controller. A common problem is inconsistent braking caused by a malfunctioning controller. This can result from incorrect gain settings, faulty wiring, or a worn-out controller unit. Ensuring your controller is compatible with your trailer’s brake system and properly calibrated is critical to avoid uneven or weak braking.
Worn Brake Shoes
Brake shoes in Scamp trailers wear down over time due to friction against the brake drum. Worn shoes reduce braking efficiency and can cause noise or dragging. Regular inspection every 12,000 miles or annually is recommended. Replacing worn shoes promptly restores braking performance and prevents damage to the brake drums.
Corroded Brake Wiring
Exposure to road salt, moisture, and debris can corrode the wiring harness connected to the trailer brakes. Corrosion leads to intermittent brake signals or complete brake failure. Inspecting wiring for rust or breaks, especially at connectors and junctions, and applying dielectric grease can help maintain a reliable electrical connection.
Adjuster Mechanism Seizing
Inside the brake drum, the star wheel adjuster maintains proper shoe-to-drum clearance. Over time, dirt and rust can cause the adjuster to seize, preventing automatic adjustment. This results in reduced braking force and uneven shoe wear. Cleaning and lubricating the adjuster mechanism during brake servicing ensures smooth operation and consistent brake performance.
Contaminated Brake Shoes
Brake shoes can become contaminated with grease, oil, or brake fluid, significantly reducing friction and braking power. This contamination often occurs due to leaking wheel bearings or brake wheel cylinders. Identifying and repairing leaks promptly and replacing contaminated shoes is necessary to restore safe braking functionality.
Inadequate Brake Drum Condition
Brake drums can develop grooves, cracks, or become out of round after prolonged use or overheating. Damaged drums cause vibration, noise, and compromised braking. Drums should be inspected for wear and measured for thickness; resurfacing or replacement is required if they exceed manufacturer specifications or show structural damage.
Faulty Breakaway Switch
Scamp trailers equipped with electric brakes often have a breakaway switch designed to apply brakes if the trailer detaches from the tow vehicle. A malfunctioning or improperly wired breakaway switch can cause brakes to engage unexpectedly or not at all during emergencies. Regular testing and correct installation of the breakaway kit are vital for safety.
Improper Brake Adjustment
Incorrect manual or automatic brake adjustment can lead to poor braking response or dragging brakes. For Scamp trailers with electric drum brakes, the shoes must be adjusted close enough to the drum to engage promptly but not so tight as to cause constant friction. Using a brake adjustment tool or following the manufacturer’s procedure ensures optimal brake shoe clearance.
Battery or Power Supply Issues
Electric trailer brakes require a stable 12V power source, often from the tow vehicle or a dedicated trailer battery. Low voltage caused by a weak battery, poor ground connection, or corroded terminals can impair brake function. Checking and maintaining battery health and ensuring solid electrical connections can prevent brake controller failures.
Overheated Brakes Due to Excessive Load
Overloading your Scamp trailer or towing in mountainous terrain without proper brake usage can cause brakes to overheat, leading to glazing of brake shoes or warped drums. This reduces friction and braking effectiveness. Using a properly sized brake controller with proportional braking and avoiding exceeding the trailer’s gross vehicle weight rating (GVWR) helps prevent overheating.
How to Choose
When addressing Scamp trailer brake problems, prioritize safety and compatibility. Key factors include the type of brake system (electric drum brakes are standard on Scamp trailers), the quality and compatibility of replacement parts, and access to proper tools for maintenance. Selecting a reliable electric brake controller that matches your tow vehicle’s output and your trailer’s brake rating is essential. Regular inspections and preventive maintenance will often reduce the risk of breakdowns. Also, consider professional servicing if you’re unfamiliar with brake systems, as improper repairs can compromise safety.
Frequently Asked Questions
Q: How often should I inspect my Scamp trailer brakes?
A: Inspect the brakes at least once a year or every 12,000 miles, whichever comes first, and after heavy towing or long trips.
Q: Can I use any electric brake controller with my Scamp trailer?
A: No, you should use a controller compatible with electric drum brakes and capable of matching your trailer’s brake amperage for proper function.
Q: What causes my trailer brakes to drag after stopping?
A: Dragging can be caused by over-adjusted brake shoes, a seized adjuster, or contaminated shoes sticking to the drum.
Q: How do I know if my breakaway switch is working?
A: Test the breakaway switch by pulling the cable with the trailer disconnected; it should activate the trailer brakes immediately.
Q: Is it safe to tow if my trailer brakes are squeaking?
A: Squeaking usually indicates worn or contaminated brake shoes; it’s best to inspect and service the brakes before towing to ensure safety.
Q: Can I upgrade my Scamp trailer brakes to electric-over-hydraulic?
A: While possible, this requires significant modification and professional installation to ensure compatibility and safety.
Final Thoughts
Understanding and addressing common brake problems in Scamp trailers is crucial for safe and enjoyable towing experiences. Regular inspections, timely maintenance, and using the correct replacement parts can prevent most brake-related issues. If you encounter persistent or complex problems, consulting a professional trailer service technician is advisable. Keeping your brakes in excellent condition not only protects you and your vehicle but also ensures your Scamp trailer performs reliably on every trip.
