Product Details

The ACDelco 18M1746 Professional Brake Master Cylinder Assembly is a premium aftermarket replacement designed to restore reliable hydraulic braking performance. Built with a combination of cast iron and aluminum construction, this master cylinder delivers a durable, high-quality fit without placing unnecessary stress on the brake booster mounting.

Key Features:

  • EPDM and SBR rubber seals — Ethylene Propylene (EPDM) and Styrene Butadiene (SBR) rubber components provide superior resistance to heat, corrosion, and fluid leakage
  • Precision geometrical tolerances — Ensures the housing and plastic reservoir mate correctly for a leak-free, proper fit
  • Piston assembly and return spring — Helps prevent brake drag, reducing the risk of premature brake pad wear
  • Pressure tested — Every unit is pressure tested prior to shipment to ensure safe, confident braking performance
  • Meets SAE J1153 and J1154 standards — Validated to meet industry brake performance testing requirements for reliability and quality
  • Power brake compatible — Designed for use with power brake booster systems
  • Ready to install — Pre-assembled and ready to bench bleed straight out of the box; no additional assembly required

Backed by ACDelco's reputation as a trusted GM-affiliated parts brand, the 18M1746 is manufactured to meet or exceed OEM specifications for fit, form, and function — making it a smart, dependable choice for brake system service.

Outstanding service & quick delivery.

Awesome prices

I have attempted to order this item on a few occasions and each time it has been canceled by your business. I hope this time the order can be fulfilled.

WE RECEIVED THE PART IN A TIMELY FASHION.

Keep it up and work on less expensive economy shipping option

very east to order online

very pleased with the service I recieved. shipping was fast, part was perfect. price was half of other dealers. will be using Autoplicity again. thanks

Fast checkout, Fast shipping thanks !!!

Quick note easy

Best price I could find, and free shipping. ..I am hoping to get the tank soon

Great

The application will work but I have to modify it slightly as the bolt circle in a little undersized for my application.

Great seller, best prices around! Order Number: 11348

Extremely easy and the best price by far.

Arrived in 4 business days and cheapest price on the web for the part I got.

I am glad I found Autoplicity! Great prices, fast shipping, and excellent customer service. Already looking at other items to purchase from them. I highly recommend using Autoplicity!

Best price on Toyo tires I could find anywhere! And the shipping was $0.10 on the dollar compared to all the other tire retailers I checked. Definitely will order again from Autoplicity.

Perfect

Was easy to purchase online as long as it IS actually in stock. Shipping price does seem a little high for such a small and light weight package.

Great experience, fast and easy.

Lowest price usually means sub-par customer service. Not the case at Autoplicity. I had questions after my item shipped, they responded promptly and professionally multiple times, and were totally willing to work with me. Very satisfying, would not hesitate to order from Autoplicity again.
