Caravan brakes don’t usually fail suddenly — they deteriorate gradually. Reduced stopping power, uneven braking, or overheating often creep in slowly, especially after long trips or extended storage.
Regular brake inspection and correct adjustment are critical for safe towing, protecting your caravan, and reducing wear on your tow vehicle.
This guide explains how to inspect caravan brakes, when adjustment is appropriate, and when the job should be handed over to a professional.
What You’ll Learn
- How caravan braking systems work
- What to inspect before adjusting anything
- How manual brake adjustment is performed
- Clear signs it’s time to book a professional service
This guide is suitable for confident DIYers, but inspection alone is valuable for all owners.
Types of Caravan Brakes
Most caravans use:
- Electric drum brakes
- Electric-over-hydraulic systems (less common)
This guide focuses on electric drum brakes, which are the most common on Australian caravans.
Why Caravan Brake Inspection Matters
Poorly adjusted or worn brakes can cause:
- Increased stopping distances
- Brake fade or overheating
- Uneven braking across axles
- Excessive wear on hubs and bearings
Brakes work hardest when descending hills or towing at highway speeds — exactly when you need them most.
Step-by-Step: How to Inspect Caravan Brakes
1. Start With a Visual Inspection
Before adjusting anything, check:
- Brake wiring and connectors
- Signs of grease contamination
- Excessive dust buildup
- Loose or damaged components
2. Listen and Feel During Towing
While towing, note:
- Squealing or grinding noises
- Pulling to one side under braking
- Reduced braking response
These are early warning signs.
When Should Caravan Brakes Be Adjusted?
Brakes typically need adjustment:
- After wheel bearing servicing
- Every 6–12 months
- If braking feels weak or uneven
- After extended storage
Adjustment compensates for shoe wear inside the drum.
Step-by-Step: How to Adjust Caravan Brakes (Manual Adjustment)
⚠️ Important: If you’re unsure at any stage, stop and book a professional service.
1. Secure and Raise the Caravan
Chock wheels, jack safely, and support with axle stands. Remove the wheel.
2. Adjust the Brake Shoes
Using a brake adjuster tool or screwdriver:
- Rotate the adjuster until resistance is felt
- Spin the drum to ensure slight drag
- Back off slightly until the wheel spins freely
Repeat for each wheel.
3. Road Test and Controller Adjustment
After mechanical adjustment:
- Refit wheels and torque correctly
- Test brakes at low speed
- Adjust brake controller as needed
Correct mechanical adjustment comes before controller tuning.
When to Call a Professional
Book a service if you notice:
- Grease-contaminated brake shoes
- Excessive brake dust or scoring
- Uneven braking across axles
- Hydraulic or unfamiliar brake systems
Brake servicing is safety-critical — there’s no downside to professional help.
Common Caravan Brake Mistakes
- Adjusting controller instead of brakes
- Skipping mechanical adjustment
- Ignoring contamination or wear
- Uneven adjustment across wheels
Brakes must be adjusted evenly to work properly.
Key Takeaways
- Brake inspection should be routine
- Mechanical adjustment matters more than controller settings
- Small adjustments make a big difference
- Safety always comes first
