Product Description

The Webb 61528B is a 15 x 4-inch balanced cast-iron brake drum with an outboard mounting configuration. It is identified in existing inventory by the Webb 61528 number and Gunite 3721AX interchange.
The 61528B belongs to a group of similar 15-inch Webb drums where pilot diameter, mounting-hole size, bolt circle, and overall depth are important for positive identification. Gunite 3721AX should be retained in the product record as a useful interchange number.

Identification Note: Do not interchange this drum with a similar 15-inch Webb drum based only on brake size. Confirm the pilot diameter, bolt circle, mounting-hole diameter, brake surface width, overall depth, and mounting configuration.
