Safe Handling:

• Brake drums are heavy; use appropriate lifting equipment
• Handle carefully to avoid impacts that could cause cracks.
• Do not drop or subject to strong impacts
• Wear work gloves when handling to avoid cuts
• Check that the packaging is intact before opening
• Visually inspect the drum before installation
• Do not install drums that show cracks, warping, or damage

Corrosion Protection:

• The new drums come with a protective coating against rust.
• Do not remove the covering until the time of installation
• If the drum is stored for extended periods, apply protective oil.
• Inspect for rust before installation
• Clean any surface rust with a wire brush before installing

Before Installation:

• Inspect the drum for shipping or storage damage
• Verify that the part number matches your application
• Confirm the number of lug nuts and the drum diameter
• Make sure you have all the necessary tools and components
• Check the condition of the brake pads, adjusters, and brake chambers
• Clean the mounting area before installation

⚠️ Warning: Brake drums are safety-critical components. Always use appropriate mechanical supports when working on the brake system. Never work under a vehicle supported only by hydraulic jacks.

🔧 Why Invest in OEM Brand Brake Drums

A cheap or rebuilt drum often has variations in metal thickness, which causes it to become oval-shaped with heavy use. An oval drum vibrates, heats the bearings, and eventually ruins your brake pads. By choosing Gunite or Webb, you're investing in the safety of your driver and your cargo.

Benefits of using premium brand drums:

• Superior resistance to thermal cracking during prolonged descents
• Factory dynamic balancing that eliminates vibrations in the pedal
• Optimized heat dissipation that protects brake pads from crystallization
• Perfect Drop-In fit that reduces workshop installation time
• Longer lifespan of the entire brake system

Signs that you need to replace your brake drums:

• Vibrations in the brake pedal during braking
• Visible cracks on the surface of the drum
• Uneven wear or ovalization of the drum
• Excessive overheating during descents
• Abnormal noises or squeaking during braking
• The drum has reached the maximum permissible wear limit

Critical Installation Recommendations:

• Always replace brake drums in pairs on the same axle: This ensures perfectly symmetrical braking and prevents dangerous jerking.
• Replace brake pads at the same time as drums for maximum efficiency
• Inspect and lubricate the automatic adjusters (slack adjusters)
• Check the condition of the brake chambers and air hoses
• Properly adjust the brake shoe clearance according to the manufacturer's specifications.
• Inspect the bearings and seals of the drum assembly during drum replacement.

Installation Procedure:

• Park on a level surface and apply the parking brake
• Chock the wheels to prevent movement
• Release the air pressure from the brake system
• Support the axle with appropriate jacks and stands
• Remove the old wheel and drum
• Inspect the brake pads, adjusters, and internal components
• Clean the mounting area and the bolts
• Install the new drum, aligning the studs correctly.
• Tighten the nuts in a crisscross sequence according to specifications
• Adjust the brake shoe clearance according to the manufacturer's procedure
• Reinstall the wheel and tighten according to torque specifications
• Check the operation of the brake system before operating

Inspection and Maintenance:

• Visually inspect the drums during each scheduled maintenance.
• Check for cracks, uneven wear, or ovaling
• Measure the inner diameter of the drum to check for wear.
• Inspect for overheating (blue discoloration or staining)
• Check the shoe adjustment regularly
• Inspect the automatic adjusters for proper operation

Wear Limits:

• Never exceed the maximum wear diameter marked on the drum
• Replace drums that show cracks, regardless of wear.
• Do not attempt to resurface drums beyond their service limit
• Consult the manufacturer's specifications for exact limits.

Pro Tips:

• Document the installation date and mileage for tracking
• Save the part number for future reference.
• Consider replacing all the vehicle's drums if they are of a similar age.
• Check alignment after replacing drums
• Perform brake tests in a safe area after installation
• Inspect the system for air leaks after completing the work.
