S550 Mustang TBM Modular 15/16" Bore Billet Master Cylinder Conversion Kit

Our Manual Brake Master cylinder kit utilizes a billet firewall mounting plate CNC'd from 6061 Aluminum. This plate is designed to utilize our TBM Modular Billet Tandem Master Cylinder. This requires you to drill your brake pedal for the master cylinder pushrod Kit. Includes all hardware necessary.

Years of development have went into this all new TBM Billet Modular Master Cylinder which answers the needs of racers and hot rodders alike. For years our brakes have rapidly developed to create world class braking systems. However, the control system of a car's braking system is the master cylinder. While most brake master cylinders are cast spinoffs of old technology that lack options in internal and physical outside sizing, have leaking issues, and reliability issues. The TBM brake master is a ground up engineered design to remedy those questions and offer new solutions for builders.

NOTE: Our TBM Billet 15/16 Master cylinder is only recommended for vehicles running 2 piston front brakes and 4 piston rear brakes. 

Features:

  • Master Cylinders held to exact tolerance and precision for out of the box performance
  • Compact Design fits where others don't (an inch or more shorter than standard masters)
  • Modular design allows for adaptability on the top (reservoir) and bottom (outlet plate)
  • Symmetrical Outlet plate gives you the ability to run the outlet fittings on either side of the master cylinder
  • Standard outlet plate offers better line routing than traditional master cylinders with down facing or side facing outlet fittings
  • 3an Female & 1/8" NPT outlet fittings
  • Fully captured pushrod (Zero risk of pulling out)
  • Hard Coated pistons avoid internal wear and debris with extended use that can clog and degrade brake caliper and system performance
  • Front threaded mounting holes offer ability to rigid mount the front of the master cylinder in chassis cars with add on steel plate
  • Oring construction for zero leaks
  • Easily swap from reservoir to remote mount with P/N 41-0004
  • 1lb. lighter than most aftermarket tandem master cylinders
  • Bright Black Anodize finish for ultimate durability
  • EPDM Seals
  • Stainless Hardware
  • Made completely in the USA in Bradenton, FL

Included: 

  • 6.5:1 Pedal Ratio optimized for manual brakes
  • Billet Manual Master Cylinder Firewall Plate
  • TBM Modular Billet Aluminum Tandem 15/16 bore Master Cylinder 
  • Hardware for Installation
  • Brake Push Rod w/ Heim Joint for attaching to pedal
  • Fittings for Master Cylinder

Note: We recommend a 6.5:1 pedal ratio on all manual brake systems 

*This kit does not have a push rod included, it uses the stock push rod

*You will need to run a brake pressure switch for brake lights*

Note: Slight modification to existing bolt holes on firewall needed to accommodate brake plate. Additionally, factory pedal assembly needs to be removed and studs going through firewall to hold factory master cylinder need to be removed from pedal assembly by cutting as bolts will be put in place

Note: This kit improves the brake pedal ratio for use with manual brakes vs. power brakes.  While sharing the original bolt pattern, this requires you to modify the existing hole where the master cylinder goes through the firewall to accommodate the stronger ratio. 

Note: Due to the difference in pedal travel based off of the required manual master cylinder ratio, brake light switch may require modification to work properly based off of pedal position.

Nice looking. Not very sturdy. Easy to install.
Size: 40x7 2Pcs, Color: White, Size: 40x7 2Pcs, Color: White
Update: The shelf slopes at about a 45° angle when you put anything more than about a pound on the outside edge of it. Perfectly fine up against the wall. Just seems like the braces inside aren't long enough to really give the stability needed. Bracket is nice and tight against the wall. Had to add braces underneath to hold a small plant, a photo and a small container. Wa sloping more and more each week The shelves look great and we're pretty easy to install. They have a single bracket that is very easy to mount to the wall and get nice and level.. The downside is that the bracket isn't long enough to go between studs. This seems like a pretty simple oversight. I mean why wouldn't you make it long enough to go stud to stud? Secondly and maybe more fatally the bars that go inside the shelf to support them coming out from the wall are significantly shorter than the depth of the shelf. Unfortunately this means the shelf is only supported the first few inches coming out from the wall so there is the potential for a slight lean forward.. The anchors they send are trash. Cheap soft plastic that just tears and bends with a screwdriver. I would suggest spending $2 and grabbing your own anchors from Ace or home Depot. The shelves are essentially made of a high grade cardboard kind of wood. They are not going to support much weight or last for years and years however there incredibly affordable and look nice and easy to install. Long as your expectations are right you'll be happy.

Would buy again and again
Color: Black, Size: 35.4 Inches
These are beautiful! I thought they’d be hard to install, but very straightforward and easy. They are quality and sturdy. I staggered the shelves and they hold a lot. Great value for the quality. I will be buying more for another room in the house.
