Product Details

The Raybestos MC390342 Professional Grade Brake Master Cylinder is a super-premium replacement hydraulic component engineered to restore safe, reliable braking performance. Connected directly to the brake pedal, it converts pedal force into hydraulic pressure that actuates the wheel brakes. This unit features a single-bore dual hydraulic channel design and is built to match original equipment fit, form, and function.

Key Features:

  • OE-Matched Bore Size and Finish: Cylinder bore dimensions and surface finish are held to original equipment tolerances, preventing fluid bypass that can lead to loss of hydraulic pressure
  • All-New Construction: Supplied complete with new castings, pistons, return springs, and all internal components — not a remanufactured unit
  • Leak-Free Reservoir Fit: Cylinder body and plastic reservoir are matched center-to-center for proper alignment and leak-free operation
  • EPDM and SBR Rubber Seals: High-quality rubber components provide superior resistance to heat, corrosion, and fluid leakage
  • Zinc Dichromate Trivalent Coating: Bleeder screws feature a hardened zinc dichromate trivalent coating for enhanced corrosion protection and long-term durability
  • 100% Pressure Tested: Every unit is fully pressure tested and meets SAE J1153 and J1154 requirements for consistent reliability and performance
  • Ready to Install: Ships fully assembled — no additional parts or subassembly required

Raybestos is a world-renowned manufacturer of brake system components, with a product line that includes friction materials, rotors, drums, calipers, hub assemblies, and hydraulics. The MC390342 upholds that legacy as a direct-fit replacement master cylinder designed for professional-grade results.

Lowest price, fast shipping, great service. I'll be back!

Fast and easy. Shipping could have been less expensive but overall a good deal.

So far, so good. More after receipt of product and installation. As it turned out, I ordered the wrong window kit, which is completely my fault, so I will have to pay return shipping and there will be a restock fee. Customer service dealt with my issue

Fast service

cant say much, just placed order

Very satisfying. I am thankful that your company also offered me a discount from the very beginning. It shows commitment on your behalf to satisfy your customers.

I need this for tomorrow. Thanks!

Amazon payments made it fast and more trusted. Free shipping and tax made it affordable.

Best prices by far and extremely easy to shop and buy.

Best prices I found online.. processed same day and recieved same week..packaged great and works great.

I was skeptical at first but checked it all out and it looked ligit, placed my order and wow low prices, first rate shipping and top quailty product. I am sold! will look to Autoplicity for future purchases, already told many of my friends about the fantatic deals at Autoplicity.

I was looking for a set of Warn driving lights and Google search returned Autoplicity as one of the merchants carrying the product. I couldn't believe the price and Autoplicity provided 25% off shipping. Nobody on the web can beat their prices!

quick and reasonably priced

Fast shipping, Great prices. After ordering,they sent out an email stating some items ordered may ship from the manufacturer. So, I was thinking item may take a few weeks to get. The next day I recieved email with tracking numbers saying item has shipped. So I was think ups ground 5 days maybe. I check on tracking numbers and items was out on truck for deliver. Nice! Ordered on Weekend got item on Tuesday.
