Chase Bays BMW 3 Series E36 (90-00) Dual Piston Brake Booster Delete w/ Bolt-On 6:1 Pedal Ratio

Fitment Information

• BMW 3 Series E36 (1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000) 

 Specs & Features

• Consistent and Controllable Brakes: Delivers the same braking performance every time, ideal for motorsport use. Enhances lap times and improves control for drift and rally cars.
• Adjustable Pedal Ratio: Includes a bolt-on bracket to change pedal ratio from 4:1 to 6:1, providing increased leverage on the master cylinder and unlocking powerful braking of a manual setup.
• Dual Piston Master Cylinder: Features isolated front and rear circuits within the reservoir, ensuring safety with independent braking in case of system failure. Approved by FIA, FD, SCCA, WRC, and more.
• Triple-Baffled Reservoir: Aeration and spillover proof design, constructed from 6061 aluminum, anodized black, with a laser-etched cap. Ensures smooth fluid dynamics and prevents foaming.
• High-Quality Hoses and Adapters: Uses BMRS hoses and hose ends, the same as in NASCAR and Indy Car. Includes -6AN stainless steel, Teflon PTFE lined high-pressure hoses, and abrasion-resistant, black nylon-sheathed hoses.
• Optional Setrab Oil Cooler: Provides an additional 20º F temperature drop, mounts under the driver side headlight or center for optimal airflow.
• Precision and Consistency: Manual brakes provide consistent braking performance, crucial for motorsport applications.
• Enhanced Control: Improved modulation of braking force, particularly beneficial in the 90-99% braking zone.
• Reduced Leg Effort: Improved pedal ratio allows for greater mechanical advantage, translating to less leg effort and more braking power.
• Reliability: Manual brakes eliminate the inconsistencies of power brakes, ensuring the same braking response lap after lap.

Product Description

Chase Bays's Manual Brake Conversion Kit ensures consistent and controllable braking for improved lap times and more precise control in drift and rally cars. Unlike power brakes, this setup provides exact braking every time, thanks to a pedal ratio change from 4:1 to 6:1 via a supplied bolt-on bracket, unlocking powerful manual braking. The true dual piston master cylinder and isolated front and rear circuits within the reservoir ensure safety, as losing front brakes still leaves rear brakes operational, making it suitable for FIA, FD, SCCA, WRC, and other sanctioning bodies. The fastest road race cars, from F1 to GT4, use manual brakes, and Chase Bays's kit replicates this high-performance setup without the complexity of an under-dash pedal box. With over 15,000 setups sold, Chase Bays's expertise guarantees that manual brakes deliver the exact braking needed for top performance. The kit includes a 1-inch bore ultra-compact master cylinder, isolated F/R circuit high-heat polypropylene fluid reservoir, billet Chase Bays reservoir cap, billet MC/firewall adapter plate, L-banjo front outlet fitting, SS rear outlet hardline, adjustable bias valve, carbon 4140 steel push rod, and stainless steel bolt-on 6:1 ratio pedal adapter. This setup reduces leg effort while increasing braking power, perfect for both road racing and the dynamic braking demands of drift and rally environments. Manual brakes thrive in the 90-99% braking zone, providing consistent modulation just before lockup, unlike touchy power brakes. Chase Bays's kit offers a cost-effective solution for achieving high-end motorsport brakes without extensive modifications, making it an ideal choice for serious drivers.
