99-07 Silverado TBM Modular Bore Billet Master Cylinder Conversion Kit (Choose Bore Size)

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.

Sizing Guideline

15/16" Bore Size: Our TBM Billet 15/16" Master cylinder is only recommended for vehicles running 2 piston front brakes and 4 piston rear brakes at 6:1 Pedal Ratio.

1.032" Bore Size: Our TBM Billet 1.032" Master cylinder is recommended for vehicles running 4 piston front brakes and 4 piston rear brakes at 6:1 Pedal Ratio.

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: 

  • 6:1 Pedal Ratio optimized for manual brakes
  • Billet Manual Master Cylinder Firewall Plate
  • TBM Modular Billet Aluminum Tandem bore Master Cylinder 
  • Hardware for Installation
  • Brake Push Rod w/ Heim Joint for attaching to pedal
  • Fittings for Master Cylinder

*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*

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.

Go buy these heels socks they’re the best
Size: 6 Pairs - 6 Colors Assorted
I love that they have gel in the heels. I sleep in a pair and even wear a pair to work for extra protection for my heels. They are great to get your heels soft and prepared for the sandal wearing days of summer. They slide on my feet so comfortably because of the great stretch they have. I just love how they feel on my feet , walking in them is very easy and comfy and they don’t slide or is slippery. You can even wash them like regular socks and wear them over and over. I would recommend them to anyone who wants baby soft heels.

Love these
Size: 6 Pairs - 6 Colors Assorted
These are fantastic if you want a 'foot mask on the go'. They fit easy, the colors are great, and they work! I used them after putting on moisturizer and my heels were smooth and looked great in sandals after! No cracks or dry patches!

These really work.
Size: 6 Pairs - 6 Colors Assorted
Very pleased with these. They really work, especially if using a pumice in the morning after removing them, makes it really easy to remove dead skin. They are very soft and reasonably comfortable so it’s not an issue during sleep. Not really a fan of the rose scent but that’s not too strong and dissipates after a few days. These wash well. It would be nice if the hem seam at the front end was finished the same way as the ankle end. This is very nice and flat, the one at the front has a bit of a protruding roll. Altogether, these are worth it. They do the job, are comfortable, and a good value.

A must for dry cracked heels.
Size: 6 Pairs - 6 Colors Assorted
I have to keep on top of my feet because the bottom of my heels get really dry. I have to soak them every 2 weeks so they don't look like horse hooves. With the spring and summer coming, the feet get drier , flip flops and sandals or any shoes without shocks really make them feel worse. These REALLY help maintain my soles beautiful and cushiony. I love to be barefoot around the house and these give the the feel of barefeet and the comfort of a sock on the heel. At night i always put lotion on my feet but can't sleep with socks because i overheat, these i can put my lotion and then a little urea stick on the heel and put them on and sleep like a baby. These need to be hanwashed and air dried to preserve the integrity of the gel on the sock. Just be aware of that. Fit wise i am a 7.5 on the wider side and these fit very well without being tight anywhere. I also put these on with flip flops and they look great and feel better too.

definitely recommend these to anyone who’s struggling with rough dry heels
Size: 6 Pairs - 6 Colors Assorted
I was pleasantly surprised by the effectiveness of these socks. They feature a soft gel-lined interior that helps absorb intense moisture from my dry heels. After wearing them for a couple of nights, I noticed a significant improvement in the texture and appearance of my heels. These socks stay in place while sleeping and don’t slip off. Additionally, I appreciate that they are reusable and can be washed.
