Dorman - First Stop Brake Hydraulic Hose P/N:H380071
Replace a worn rear right brake flex line on your 2002-2007 Buick Rendezvous or 2001-2005 Pontiac Aztek with this Dorman brake hydraulic hose, part number H620030 from the Dorman - First Stop line. The flexible hose carries pressurized brake fluid from the vehicle's rigid brake line to the brake at the wheel, and it flexes as the suspension moves. Dorman precision-engineers it to match the performance of the original brake hose on specific vehicles and positions, as part of a complete brake repair.
A brake hose may need replacing if its outer cover is cracked, bulging or chafed, if fluid seeps at the hose or its fittings, or if the brake pedal feels soft or spongy. Diagnose the cause before replacing parts. This listing is for the rear right hose only. Bleed the brake system after installation, following the vehicle service procedure. See the Buyer's Guide tab for engine details.
