Brake Shoe
Frequently Asked Questions
Q: What is the purpose of a brake shoe in electric lift truck brake systems?
A: A brake shoe is a curved friction component that presses against the brake drum to create stopping force. The CT 91E46-00113 is engineered for Caterpillar electric lift truck service brake and parking brake systems, providing reliable deceleration and load holding.
Q: What type of friction material is on the CT 91E46-00113 brake shoe?
A: The specific friction material composition is detailed in the OEM specification. Caterpillar brake shoes typically use asbestos-free, semi-metallic or organic friction material formulated for consistent performance across temperature ranges and load cycles common to warehouse operations.
Q: How do I know when the CT 91E46-00113 brake shoe needs replacement?
A: Replace brake shoes when friction material wear exceeds OEM thickness limits (typically 2mm minimum), when brake pedal travel increases noticeably, or if braking becomes soft and requires longer stopping distances. Worn shoes reduce braking power and increase wear on the brake drum.
Q: Are brake shoes sold individually or in sets for electric lift trucks?
A: Brake shoes are typically replaced in complete sets (both leading and trailing shoes per brake assembly) to ensure even wear, balanced braking, and predictable performance. Never replace a single shoe or mix old and new shoes in the same brake assembly.
Q: What is the lifespan of the CT 91E46-00113 brake shoe in field service?
A: Brake shoe life depends on equipment usage intensity, load weight, ambient temperature, and maintenance. In typical warehouse electric lift truck service, shoes last 18-36 months before friction material wear requires replacement. Frequent hard braking and wet conditions shorten lifespan significantly.
