Brake Assembly for Radial Arm Saws

Reliable Motor Starts and Safe Braking

The Brake Coil Assembly is a vital component of the braking system in Contractor Duty and Heavy Duty radial arm saws. This electromagnetic coil energizes to pull the steel brake disc away from the fan and liner, allowing the motor to spin freely and ensuring smooth operation.

Key Features

• Essential Function – Disengages the brake disc to let the motor free spin.
• Built for Safety – Prevents hard starts and ensures proper braking performance.
• Durable Design – Designed to deliver reliable performance under continuous use.

When to Replace Your Brake Coil Assembly

• Hard Starts or Motor Won’t Start – A failing brake coil makes the motor hard to start or prevents it from starting altogether.
• Brake Fails to Disengage – If the brake disc fails to release, the coil may no longer be functioning correctly.
• Ohms Test Failure – The brake coil should measure between 700 and 800 ohms. Readings outside this range indicate the brake coil assembly needs replacement.

Compatibility

• Original Saw Contractor Duty Radial Arm Saws (Type 4 and newer)
• Original Saw Heavy Duty Radial Arm Saws
• Certain 3500 Series DeWalt Radial Arm Saw motors
