Detailed Description

This Dorman brake hose is built for specific rear brake applications where a flexible hydraulic line is needed to connect the brake system components while maintaining proper fluid transfer and movement at the wheel end. The hose uses EPDM rubber for the outer and hose material, with treated steel female fittings at both ends for a secure connection. It is a direct-fit replacement for 1984-1994 Ford Tempo rear left and rear right, 1984-1994 Mercury Topaz rear left and rear right, 1981-1990 Ford Escort rear left and rear right, 1981-1985 Mercury Lynx rear left and rear right, and 1982-1983 Mercury LN7 rear left and rear right. If you are servicing a Ford Tempo brake hose, Mercury Topaz rear brake line, or Ford Escort rear hydraulic hose, H38378 provides the correct fitment profile for those listed positions. This part cross-references Gates 77700 for the same application.

What It Helps Address

• Cracked or deteriorated brake hose rubber
• Brake fluid seepage at the hose connection
• Restricted hydraulic flow from an aged flexible line
• Brake pull or uneven rear brake response caused by hose wear
• Service issues on rear left or rear right brake hose locations

Installation Notes and Tips

Verify the vehicle year, make, model, and rear position before ordering. Compare the original hose length, fitting style, and thread size to the specifications listed here, including the 3/8 in-24 thread diameter and female-to-female end configuration. Because mounting hardware, brackets, gaskets, and seals are not included, reuse or source the required related components as needed during brake repair. After installation, bleed the brake system and inspect all connections for leaks.

Quality Assurance

Dorman designs this brake hydraulic hose to match the original hose’s fit, function, and performance on the listed vehicles and positions. The H38378 is intended as a durable replacement part for complete brake repair on compatible rear brake applications.
