Buy Ford Thunderbird Drum Brake Adjusting Screw Assemblys

The drum brake adjusting screw assembly, also known as the brake adjuster or star wheel adjuster, is a crucial component in drum brake systems. It maintains the correct distance between the brake shoes and the drum, ensuring optimal braking performance and even wear of brake components.

The primary function of the brake adjuster assembly is to compensate for the gradual wear of brake shoes. As the brake shoes wear down, the gap between the shoes and the drum increases. The adjuster automatically or manually adjusts this gap, maintaining proper contact and ensuring consistent braking response.

Faulty or worn brake adjusters can lead to several issues:

Reduced Braking Efficiency: An excessive gap can cause decreased braking power, leading to longer stopping distances.
Uneven Brake Wear: Improper adjustment may result in one brake shoe wearing more than the other.
Brake Dragging: If the adjuster seizes or is incorrectly adjusted, the brake shoes may remain in contact with the drum, causing overheating.
Noisy Brakes: Squeaking or grinding noises can occur due to improper shoe-to-drum contact.

Regular Inspection: Check the brake adjuster assembly during routine brake maintenance to ensure it moves freely.
Proper Lubrication: Apply high-temperature brake grease to the adjuster threads to prevent corrosion and ensure smooth operation.
Correct Installation: When installing a new adjuster, ensure it is properly seated and aligned with the brake shoes and adjuster lever.
Adjustment Procedure: Follow the manufacturer's guidelines for adjusting the brake shoes, typically involving turning the star wheel to achieve the correct shoe-to-drum clearance.
Avoid Overtightening: Do not over-adjust the brakes, as this can cause dragging and excessive wear.

Signs of Wear: Replace the adjuster assembly if it shows signs of corrosion, stripped threads, or if the star wheel is difficult to turn.
Compatibility: Use an adjuster assembly that is compatible with your specific vehicle make and model.
Professional Assistance: If unsure about installation or adjustment procedures, consult a qualified mechanic to ensure safety and proper function.
