Description
Product Overview
The munirater brake proportioning valve is a high‑quality metal component engineered to replace part number 172‑2069 in 1989‑1994 Chevrolet C/K trucks. Measuring 5.91 x 3.74 x 8.66 inches and weighing just 14 ounces, the valve features a robust metal construction that meets ANSI B16.11 standards. It includes a flare inlet connection and a standard outlet, providing two ports for precise modulation of brake pressure between front and rear axle groups. This design ensures balanced braking performance, especially under heavy load conditions.
Usage
Ideal for light‑truck owners, fleet managers, and automotive repair shops, this valve restores original brake feel and safety after wear or failure. Install it in the brake proportioning circuit of compatible Chevy C/K models to achieve consistent pedal response and reduced brake fade. It performs reliably in daily driving, towing, and off‑road scenarios where brake balance is critical.

FAQ
Is this valve compatible with all 1989‑1994 Chevy C/K models?
Yes, it is engineered as a direct replacement for the original part 172‑2069 used in those model years.
Do I need additional hardware to install the valve?
No additional hardware is required; the valve includes the necessary flare inlet and standard outlet fittings.
Can this valve be used on vehicles other than Chevy C/K trucks?
It is specifically sized and calibrated for Chevy C/K applications, so use on other makes may not provide correct brake balance.
What is the expected lifespan of the valve?
With proper maintenance, the metal valve can last the lifetime of the vehicle, often exceeding 100,000 miles.
How does the proportioning valve improve braking?
It adjusts the pressure sent to front and rear brakes, preventing rear‑wheel lockup and ensuring smoother, more controlled stops.
