This will present you with the correct system in later options. It's important to choose the right caliper so that you are provided with the right master cylinder & caliper option.

Note: The Front T-bird calipers are only compatible with rear drums or explorer rear disc for our premium hydroboost. If you are installing t-bird front calipers and a gm style rear caliper you can only use our classic hydroboost system.

Choose between rear drums, explorer rear disc brakes, or GM style rear disc conversion.

Note: This system does not include any rear brake parts. This step is just to insure that you are provided with the right master cylinder.

We offer two different styles of Hydroboost which gives you the option to mount a classic or modern master cylinder to it.

Classic: This system uses a classic cast aluminum (RUST FREE) master cylinder and uses a standard frame-mounted proportioning valve. With an optional stainless steel fascia plate we offer to use it as a template to cut your firewall and hide any imperfections that may be behind your power brake booster after you remove it.

Premium: This system includes the compact bullet-style Wilwood master cylinder combined with their adjustable proportioning valve. It also includes the stainless steel fascia plate we offer to use as a template to cut your firewall and hide any imperfections that may be behind your power brake booster after you remove it.

We also offer the "mod" or "no mod" system depending on your application. The mod will require enlarging the hole in the firewall that the brake pedal rod passes through to complete the installation. The no mod system if available for your application will bolt in without modification to the firewall.
