VALVE, PWR BRK (P/N 38-675) - As Removed

The 38-675 is a power brake valve for aircraft hydraulic braking systems. This valve meters pilot-applied pressure from the master cylinder to the wheel brakes or anti-skid manifold, enabling proportional braking control. Installed between the pedal linkage and brake calipers, it converts pilot input into regulated hydraulic flow for smooth, controlled deceleration.

Installation requires bleeding per aircraft maintenance manual specifications and FAA AC 43.13-1B guidance. Verify part compatibility with your aircraft's Illustrated Parts Catalog before installation.

What is the VALVE, PWR BRK (P/N 38-675)?

The 38-675 is a power brake valve for aircraft hydraulic braking systems. This valve meters pilot-applied pressure from the master cylinder to the wheel brakes or anti-skid manifold, enabling proportional braking control.

What hydraulic fluid type is the 38-675 compatible with?

Hydraulic component compatibility depends on the aircraft system design. Common aviation hydraulic fluids include MIL-PRF-5606 (mineral-based), MIL-PRF-83282 (synthetic), and Skydrol (phosphate ester). Verify the VALVE, PWR BRK against your aircraft maintenance manual for fluid compatibility.
