If you want to improve the brake feel in your track car, the VBBC is worth a look. It’s used to fine-tune brake feel. I’ll let you visit their website to get the engineering behind it.
It was super easy to install. There are a couple plugs and barb fittings that come loose in the package. You’ll start by installing these. You’ll need to use teflon tape (yuck) or thread sealant (yes) on these. Doing this part takes 5 minutes. Next remove the hose end from your brake booster. Attach it to the correct end of the controller. Attach a U-shaped hose in the correct orientation to the booster and other end of the controller. Put all the hose clamps in place and turn the controller all the way to the + side. That’s it. Installation complete.
I got the unit to solve a shortage of modulation I have with my favorite brake pads – Raybestos ST43. They are super grippy and I don’t have the modulation I want. I got used to it but they are very touchy. The first day with the VBBC, I didn’t have time to adjust it. I was too busy adjusting tire pressures, talking to people… you know the routine. I had it fully on the + side and didn’t notice any difference in my brakes.
Next day I gave it one full turn to the negative side and pushed the dial down to lock it into place. Back on track. Braking into the first corner I instantly felt the difference. I had more modulation and better brake feel! I noticed it every time I hit the brakes. I had more control, a greater ability to finesse the brakes. I didn’t touch the VBBC again.
I may try more adjusting in the future to see what difference it makes but one turn and one day on track made it worth it for me!
BOTTOM LINE: If you aren’t happy with your brake feel and modulation, the SakeBomb Garage Variable Brake Booster Controller (VBBC) is definitely worth a look. I couldn’t be more pleased.
