Chase Bays Dual Piston Brake Booster Delete with Bolt-On 6:1 Pedal Ratio | (CB-DBBE-U)

Dual Piston Brake Booster Delete with Bolt-On 6:1 Pedal Ratio by Chase Bays

A properly set up Manual Brake Conversion Kit improves lap times and makes for a more controllable drift / rally car. There is a lot of incorrect information out there about Manual Brakes, from forums to other videos. Chase Bays has sold over 15,000 Manual Brake setups in the last 10 years€¦everything from winning Road Race chassis to winning Drift chassis.

A proper manual brake setup (matched ratio with MC bore size, good pad compound, and Front / Rear Bias Adjustment) is the exact same braking every time. The modulation of max braking just before lockup is where manual brakes really thrive. Chase Bays calls it the 90-99% zone. Finding the exact level of leg pressure to get that exact threshold is just not possible with power brakes, theyre too inconsistent...especially with boost. Acquired Motorsport Data isnt wrong. YES the 90-99% zone is a little more leg effort than power brakes but thats what makes it so great. This is massively to our benefit in finding the right leg force every time.

Chase Bays firmly believes in the quote "Success is in the details." One look at their products, and you'll note how detail oriented they are. From the initial thought and idea, the R&D, the testing, and the final release to being a product for sale. Nothing is left out and Chase Bays tries to consider everything. Their products are rigorously tested to make sure they work well against their own abuse and eventually yours.

Please Note: You will need to purchase the Chase Bays Brake Line relocation kit for your platform or make custom lines if they are not available. (All 3 outlets are -3AN Male). This product may require modification to your firewall to accept the new brake booster shape, see "Clearancing Guide" in the References section for additional information.
