Chevrolet Front/Rear Brake Lines 1901-1904 OEM 18J3815

This ACDelco brake lines for 1901-1904 Chevrolet matches OE routing and flare geometry for a leak-free service replacement.

Formed steel brake lines carry the hydraulic pressure between the master cylinder, ABS module, and the flexible hoses at each wheel. In salt-belt service the line corrodes from the outside, pinholes under load, and can dump the fluid on a single brake apply. Replacing corroded sections proactively is cheap insurance.Fits front and rear axle positions on this platform.

Verify your fitment with the year, make, model, and trim of your vehicle before ordering. If you are not sure, contact us with your VIN or vehicle configuration and we will match the correct part to your application before you buy.

Cross-Reference

Manufacturer part number 18J3815. This is a ACDelco catalog part. Confirm the OE reference for your vehicle matches before installing.

Why You Might Need This

Rust on a formed steel brake line is not cosmetic. A pinhole leak under brake apply is a full-loss failure on that circuit and a pedal-to-the-floor experience. Replace corroded sections proactively in salt-belt service.

Installation Notes

Use the correct double- or ISO-flare on any cut-and-flare repair section. Route the new line clear of moving suspension components and exhaust heat. Bleed the brakes fully after replacement.
