Description

Overview

The E8P air brake foot valve gives the driver graduated control of primary and secondary service brakes in a dual circuit system. It mounts on the floor and links directly to the treadle so brake feel stays consistent and predictable. In a heavy vehicle and trailer combination, this valve controls both circuits so a single pedal movement applies and releases the brakes smoothly. Additionally, separate supply and delivery circuits help maintain control if one circuit loses pressure.

Features

Key features of this E8P air brake foot valve include:

• Dual circuit layout with separate primary and secondary supply and delivery ports for service braking.
• Floor mounted design that connects to the treadle for direct, repeatable brake pedal response.
• Basic valve body supplied without treadle or mounting plate so you can reuse existing hardware.
• Common 3/8in port sizing that simplifies plumbing into established air brake systems.

Specifications and Materials

This dual circuit foot valve uses 3/8in 18 thread supply ports and 3/8in 18 thread delivery ports so it suits many E8P style air brake layouts. It works as a service valve for two separate circuits, which gives the driver fine control over brake application and release in line with Bendix E series design practice.

Part number: AB8412.

Compliance and Safety

A correctly operating E8P air brake foot valve plays a critical role in ADR compliant heavy vehicle braking because it manages both primary and secondary service circuits. When you install this valve, follow workshop procedures, support the treadle correctly and connect each port to the matching circuit. Additionally, always pressure test the system, check for leaks at every fitting and verify that pedal travel and response match your fleet standards before returning the vehicle to service.

Trailer Applications

This air brake foot valve dual circuit arrangement suits prime movers and rigid trucks that tow semi trailers, dog trailers or B double combinations. It typically mounts on the cab floor above or near the main air valve cluster, where it interfaces with relay valves and trailer control valves. Moreover, it works as a service replacement wherever an E8P style dual circuit foot valve previously controlled both service circuits from a single pedal.

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

Always confirm port sizes, layout and mounting details against the valve you remove so the replacement installs cleanly in your existing air brake system.
