65-66 Mustang Modular Motor Hydroboost Hydraulic Power Brake Boost Assembly

Designed Specifically for FORD 5.0L V8 COYOTE ENGINE SWAPS in Classic Mustangs

SKU: HTB-5661L

Hydro boost Power Brake Assist Assembly designed for 65-66 Mustangs with Modular Coyote 5.0 Engine Conversions

Upgrade your Classic 65-66 Mustang's braking power with our high-performance Hydraulic Brake Assist System. This hydraulic brake assist system is designed with a cantilever firewall bracket that is designed to bolt up to your classic Mustang firewall but provides the height to clear the wide Coyote Modular 5.0 Engine and other Ford Modular conversions where a Factory vacuum booster will not clear!

Every system is built entirely from brand-new parts—no remanufactured or refurbished components like some others found on the market. This Hydratech system uses only the latest production Bosch units—proven, reliable, and ready for high-performance applications. Each unit is thoroughly tested to ensure consistent and precise brake assist operation before it reaches you. No fabrication needed - Installs using common hand tools on your classic Mustang's stock firewall!

**IMPORTANT INSTALLATION NOTES (PLEASE READ BEFORE PURCHASE):

Designed for Coyote 5.0 and other Ford Modular Engines. Will NOT Work with Mustangs that have the STOCK Shock Towers in Place. Car must have a Front Suspension (TCI, Heidts, DSE, Etc.) that REMOVES Original Shock Towers and Export Brace.
If using Stock Hood Hinges, you must remove the stock springs and use a Hood Prop Rod for Proper Clearance with the Assembly on the Driver's Side
If wanting to run aftermarket Billet Hood Hinges instead, we recommend Eddie Motorsport Hinges as we know they clear this unit (See links below)
Must use a Power Steering pump that can provide the proper pressure/flow for a Hydro boost System. If unsure, please contact us before making a purchase.
We recommend the Wilwood master cylinder we offer. If you already have a master cylinder, please contact us before purchase to make sure it is compatible.
