How To Install - A Firewall-Mount Booster Option for 1947-1953 Chevy Pickups
This article on Hot Rod highlights a custom firewall-mount brake booster and pedal assembly developed by Classic Performance Products specifically for 1947–1953 Chevrolet pickups. Instead of adapting oversized boosters from donor cars (like older Camaros), this new system is compact, purpose-built, and bolt-on, requiring no firewall modifications beyond drilling mounting and pushrod holes.
Key points covered in the story:
- The kit includes a firewall-mounted booster and under-dash swing-pedal assembly, designed to fit the Advance-Design Chevy trucks without complex alterations.
- The ergonomic pedal improves leverage over the stock setup and includes an adjustable brake light switch.
- Installation is detailed on a 1949 Chevy 3100, demonstrating how the bracket slips up under the dash, aligns to the firewall, and is drilled/bottom-bolted into place.
- The kit used in the install is the 4753FBBD-8 8-inch booster with an internal combination valve, eliminating the need for an external proportioning device.
- After fitting and fine-tuning pedal pushrod preload, the article explains how the system is plumbed into the truck’s brake lines and adjusted for driver comfort.
