All maintenance providers which service Montgomery HR Series escalators are encouraged to replace the following pin drive brakes: ER-825 and ER-1225
ER-825 Permanent Magnet Spline Brake
The 8 inch ER-825 Magnet Spline Brake is a direct replacement for the older and less durable ER-825 Pin Brake, which can use the existing tachometer and/or encoder, as well as the rest of the brake system.
ER-1225 Permanent Magnet Spline Brake
The 12 inch ER-1225 Magnet Spline Brake is also a direct replacement for the older and less durable ER-1225 Pin Brake, which can (like the ER-825) use the existing tachometer and/or encoder, as well as the rest of the brake system.
