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.

As advertised for once! Lol
Color: Cooling Blue Cover, Size: Queen (Pack of 2), Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Queen size set of 2 pillows, I'm giving it 5stars first bc it has a good length and width!! If you've ever bought memory foam pillows before you know some are small!! Anyways after having it for 5nights, we loved that me and my huddy could adjust the Thickness amount we had in it to our needs, me needing a thick pillow and my husband needing a flatter one. So this was perfect for that. So far its nice to sleep on, stays cool, doesnt get hot. I would say its on the frimer side but softer the more foam you take out! Really its just good for the amount you spend!! Will it last 10years probably not but what does now a days. This is the only time my huddy n I bought the same pillow and both love it so I'm just still in shock it worked out so well!!

Adjustable pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
I love these because they don't go flat. You can pull out whatever you need to make them comfy for you. They come in two different layers. So you have that protective cover over the main case that holds the memory foam. They're amazing to sleep on. I have had these last for years without going flat. If you hate flat pillows this is the way to go. They are very easy to wash. You just have to separate layers. They are very thick, you can adjust the thickness. Everyone in my house has at least one. They are worth the money. I have never had to replace them, because they went flat.

Good pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Takes some getting used to but and the cooling doesn’t last very long in my opinion, but overall amazing comfy pillows. The materials are good and are washable. I mostly stopped waking up with a stiff neck and back.

Believe the Reviews
Color: Cooling Blue Cover, Size: King (Pack of 2)
I purchased these pillows because we were in need of new pillows, I previously had allswell pillows which were from walmart and they were good to start but now they tragically became very sparse and it started to effect my sleep so I saw these after careful review on other pillows and reviews I came across these and I saw some reviews and videos and I ordered them.. first they are king size we ordered they are perfect for the bed, they are plump and soft, they are memory foam which has always worked out for me for support and kept it’s shape these are great it did have a little smell I guess from packaging but other than that they are a huge upgrade from what we had before! I’m excited because they are cooling too! for the price point can’t beat it and this is coming from someone who was about to spend money on a purple pillow this will be good for now definitely buy it.
