A brake hose flexes every time the suspension moves, so it can wear over time. Signs it may need replacing include a soft or spongy pedal, fluid seepage around the hose or its fittings, and cracking, swelling or chafing on the hose. If a worn hose is the cause, this part replaces it. Inspect the whole brake system to confirm the diagnosis before you replace parts.

Frequently Asked Questions
What does a brake hydraulic hose do?
It carries brake fluid under pressure between the vehicle's brake line and the brake at the wheel, and it flexes as the suspension moves. This hose is cataloged for the rear left lower and rear right lower positions.
Will this Centric hose fit my 1999-2006 GMC Sierra 1500?
The 1999-2006 GMC Sierra 1500 is one of the listed applications, along with the 1999-2007 Chevrolet Silverado 1500. Use the "Vehicles it fits" section to confirm the fit for your exact truck.
What are signs a brake hose may need replacing?
A soft or spongy pedal, fluid seepage near the hose, or cracks, swelling or chafing on the hose can mean it is worn. Have the brake system inspected to confirm the cause.
Is there anything to know about installation?
The brake system must be bled after installation to remove air. Check the vehicle service information for torque values and the correct fasteners, and for whether any of the original ones may be reused.
Does this hose go on the left or right side?
It is listed for both the rear left lower and rear right lower positions on the listed applications, so the same part number serves either side.
