Proper maintenance of the YIKONG YK4107 Brake Camshaft Set (Part No. 21089) helps ensure smooth braking performance, reduces component wear, and extends the service life of the braking system. Regular cleaning, inspection, and lubrication are essential for maintaining reliable brake operation.

Why Should You Regularly Maintain the Brake Camshaft Set?
The Brake Camshaft Set is a key component of the braking system on the YIKONG YK4107. Dirt, dust, and moisture can accumulate during off-road driving, affecting braking performance and accelerating wear.
Without regular maintenance, you may experience:
-
Reduced braking performance
-
Stiff or uneven brake operation
-
Increased wear on moving parts
-
Unusual noises during braking
-
Shortened component lifespan
Maintenance is especially important after driving through mud, sand, water, or dusty environments.

How to Maintain the YIKONG YK4107 Brake Camshaft Set?
Regular cleaning, inspection, and proper lubrication are the best ways to keep the Brake Camshaft Set working smoothly.
Step 1: Turn Off the Vehicle
Switch off the YIKONG YK4107 and disconnect the battery before performing any maintenance.
Step 2: Remove the Brake Camshaft Set
Carefully remove the Brake Camshaft Set following the vehicle's assembly structure.
Keep all screws and small components organized to prevent loss.
Step 3: Clean the Components
Use a soft brush or a clean cloth to remove:
-
Dust
-
Dirt
-
Sand
-
Old grease
If necessary, use an electronic parts cleaner and allow the components to dry completely.
Step 4: Inspect the Components
Carefully check:
-
Whether the camshaft rotates smoothly
-
Whether any parts are worn or damaged
-
Whether the screws are loose
-
Whether there is excessive dirt inside the assembly
Replace any worn or damaged parts if necessary.
Step 5: Apply Lubrication
Apply a small amount of RC-grade lubricant to the camshaft pivot points and other moving contact surfaces.
Avoid excessive lubrication, as too much grease can attract dirt and reduce braking performance.
Step 6: Reinstall and Test
Reinstall the Brake Camshaft Set and ensure:
-
All screws are securely tightened
-
The camshaft moves smoothly
-
The brake mechanism operates correctly
After installation, perform a low-speed braking test before normal driving.

Daily Maintenance Tips
Routine maintenance helps keep the YIKONG YK4107 braking system operating smoothly and reliably.
Recommended practices:
-
Clean the brake components after driving in mud or sand.
-
Inspect the camshaft regularly for smooth movement.
-
Check mounting screws for tightness.
-
Remove accumulated dirt before storage.
-
Avoid prolonged exposure to water without drying the components.
Regular maintenance helps maintain consistent braking performance and extends the lifespan of the Brake Camshaft Set.
