Product Details

The Dorman H38503 is a direct-fit replacement brake hydraulic hose engineered to restore safe, reliable brake fluid transfer in your vehicle's hydraulic braking system. Manufactured to position-specific dimensions, this hose installs precisely where the original equipment hose was designed to go, eliminating guesswork and reducing installation time.

Dorman constructs this hose using EPDM rubber, a material known for its superior resistance to heat, ozone, and brake fluid degradation. Specially coated, corrosion-resistant fittings on each end ensure a secure, leak-free connection to the brake system's hard lines and calipers or wheel cylinders. Every hose in Dorman's hydraulic brake hose line is pressure-tested to 4,000 PSI to confirm it meets or exceeds government-regulated safety and durability standards.

Key Features:

  • Direct OEM replacement — manufactured to match the original hose's fit, form, and function
  • Position-specific design for precise, straightforward installation
  • EPDM rubber core resists heat, ozone, and brake fluid chemical degradation
  • Specially coated, corrosion-resistant end fittings for a leak-free seal
  • Pressure-tested to 4,000 PSI to meet government safety standards
  • Fully assembled and ready to install

Replacing worn or cracked brake hoses is a recommended part of any complete brake service. A deteriorated hose can bulge under pressure, restrict fluid flow, or leak — all of which compromise braking performance and safety. The Dorman H38503 provides a dependable, cost-effective solution backed by Dorman's engineering expertise.

I just bought two of the new Aeromotive pumps from autoplicity at the best price found online.. They were shipped out quick and arrived even faster than I thought. Autoplicity.com will be in my favorites when it comes to ordering parts for my 94 Supra from now on!!!

Good

checkout software gave me some grief first time around but finally worked ok.

Great website and the ordering was easy too. I like the way they show the full price including shipping and tax. Got the confirmation immediately and the shipment notification the next business day. <br>
