Product Details

The ACDelco 18M2404B Professional Brake Master Cylinder is a high-quality replacement unit engineered to restore proper braking performance and hydraulic pressure to your vehicle's brake system. As a core component of the hydraulic braking circuit, the master cylinder converts the mechanical force from the brake pedal into hydraulic pressure that actuates the wheel brake assemblies.

Key Features:

  • Manufactured to meet or exceed original equipment specifications for fit, form, and function
  • Precision-machined aluminum or iron bore for consistent hydraulic pressure delivery
  • Pre-filled and pre-tested reservoir cap and seals to minimize installation time
  • Corrosion-resistant construction for long service life
  • Includes integrated fluid reservoir where applicable
  • ACDelco Professional line — designed for professional technician installation and demanding service conditions

The ACDelco Professional line represents the brand's premium aftermarket offering, delivering dependable, OE-quality performance. The 18M2404B is a direct-fit replacement that simplifies installation and helps return your vehicle's braking system to factory specifications.

Great!

Great price with excellent service. I would highly recommend your company!

Great ordering experience

Easy order process. Great price. Quick delivery. 10 out of 10.

I never received anything about shipping so I contacted customer support. They said it was a direct shipment and they would check on it for me and get back to me. I never heard back from them. Shortly after that I did receive a message from the carrier saying they have my shipment and scheduled a delivery. They said they would call me 30 mins before the delivery so I could get off work and come to inspect it before signing for it. That didnt' happen either my wife called me first thing in the morning and say they are here delivering it now so I had to run home so I could inspect it. The driver was really nice and waited for me to get there.

Great pricing and super fast service!! Thank you!

QUICK AND EASY ORDER PROCESS

excellent

The only problem was confusion with process and delivery information. And the picture of the generator wasn't what my pump was for. Despite that, it was right product delivered as fast as Amazon which brought me comfort to the confusion. Thanks for your service.
