Wheel Brake Cylinder
Overview
A Wheel Brake Cylinder is an essential part of a drum brake system that helps convert hydraulic pressure from the brake fluid into mechanical force. It pushes the brake shoes outward against the brake drum, allowing the vehicle to slow down or stop effectively.
Key Functions
Converts brake fluid pressure: Receives pressure from the master cylinder during braking.
Activates brake shoes: Forces both shoes against the drum surface to create friction.
Provides balanced braking: Ensures even application of braking force on each wheel.
Typical Components
Cylinder housing
Dual pistons with rubber seals
Dust boots
Bleeder valve and return springs
