Brake Booster Kits
Power brake booster kits bring the main components of a power-assisted brake conversion together for classic cars and trucks. This collection includes vehicle-specific vacuum and hydraulic systems, firewall-mounted conversions, LS-swap options, Black Out packages, and configurations with POL or Wilwood master cylinders.
Built Around the Vehicle, Not Just the Booster
A complete brake-assist conversion depends on how the assembly mounts and connects to the vehicle. The firewall brackets must position the booster correctly, the pushrod must align with the pedal, and the master cylinder must suit the installed brake system. Vehicle-specific power brake booster kits are designed to address these connections as one package rather than leaving each part to be adapted separately.
The collection includes systems for factory-style firewall locations as well as conversions that relocate older underfloor arrangements. Selected truck kits use compact firewall-mounted assemblies to create additional clearance around the engine and valve covers. One Ford F-100 configuration, for example, combines an 8-inch dual-diaphragm booster with an adjustable pedal ratio and a 1-inch-bore master cylinder.
Other power brake booster kits are tailored to modified vehicles. The available 1967–72 Chevy and GMC truck LS-swap kit uses the original firewall mounting studs and factory pedal assembly while providing clearance for the engine conversion. Its reinforced bracket is made from 0.188-inch 1018 mild steel to reduce flex in the booster assembly.
Finish and hydraulic configuration also vary across the collection. Shoppers can choose standard plated assemblies, Black Out packages, chrome systems, and kits with POL or Wilwood master cylinders. Some listings are configured for front-disc/rear-drum brakes, while others support four-wheel-disc systems or hydraulic Hydropower assistance.
The correct power brake booster kit should match the vehicle, firewall arrangement, pedal assembly, engine clearance, brake layout, and desired master-cylinder configuration. Product contents differ, so every listing should be checked to confirm the booster, brackets, master cylinder, valve, lines, and hardware supplied.
FAQ
What is the difference between a brake booster and a brake booster kit?
A brake booster is the assist unit itself. A power brake booster kit may also include vehicle-specific firewall brackets, a pedal pushrod or clevis, a master cylinder, a proportioning valve, pre-bent lines, and mounting hardware.
Are power brake booster kits vehicle-specific?
Many products in this collection are designed around a particular vehicle and year range. Their brackets, pedal connections, booster angle, and master-cylinder position are intended to match that application.
Can a power brake booster kit convert manual brakes to power brakes?
Many kits are intended for this purpose. The conversion may replace or adapt the existing master-cylinder mount and connect the booster to the original pedal assembly. Always verify that the chosen kit specifically supports a manual-to-power conversion.
What is included with a power brake booster kit?
Contents vary significantly. Some kits include only the booster and mounting brackets, while others add a master cylinder, proportioning valve, valve bracket, lines, pedal components, and hardware. The individual product listing should be treated as the final parts list.
What is a firewall-mounted power brake booster kit?
A firewall-mounted kit positions the booster and master cylinder on the engine side of the firewall. These systems can replace an older underfloor arrangement and may improve access while creating a more compact pedal and booster assembly.
Are there power brake booster kits for LS swaps?
Yes. The collection includes LS-conversion kits designed to provide additional engine clearance while retaining application-specific firewall and pedal mounting. The 1967–72 Chevy and GMC truck version mounts to the original firewall studs and uses the factory pedal assembly.
Can I choose a POL or Wilwood master cylinder?
Selected power brake booster kits offer a choice between POL and Wilwood master cylinders. Available finishes, bore sizes, and brake configurations depend on the specific product.
What is a Blackout power brake booster kit?
Blackout kits use dark-finished boosters, master cylinders, brackets, or related components to create a coordinated appearance. Their fitment and hydraulic setup still depend on the vehicle and selected brake configuration.
Do these kits work with four-wheel disc brakes?
Some kits are specifically offered for four-wheel-disc systems, while others are configured for front discs with rear drums. The master cylinder and proportioning valve must match the chosen brake layout.
Are Hydropower systems included in this collection?
Yes. Although the collection mainly focuses on vacuum-assisted packages, it also includes Hydropower brake booster kits that use power-steering pressure instead of engine vacuum.
