A flexible brake hose links the rigid brake lines on the body to the brake at the wheel. It carries fluid under pressure while the suspension and steering move. Dorman engineered this hose to replicate the original in fit, function and performance on the specific vehicles and positions it is listed for, as part of a complete brake repair.
- Ideal replacement: precision-engineered to match the performance of the original brake hose on specific vehicles.
- Position-specific: manufactured to precise measurements for an exact fit and easy installation.
- Quality assured: materials tested to exacting government-regulated safety and durability standards.
- Durable design: made with EPDM rubber and specially coated, corrosion-resistant fittings.
A brake hose may need replacing if the rubber is cracked, swollen or bulging, if fluid seeps at the hose or its fittings, or if the brake pedal feels soft or spongy. Other brake components can cause these symptoms too, so inspect the system before you replace parts. Replacing the front left and front right hoses together is recommended. Bleed the brakes afterward as the vehicle service information directs.
