CPP BRAKE BOOSTER AND CYLINDER
30 With the truck back on the ground, we could address the booster and master cylinder. Somewhere in this truck’s past, someone thought it would be a good idea to eliminate the factory booster. We’re not sure why, or if it even worked, since the truck wasn’t running or driving when we picked it up. Luckily for us, they did leave some of the hardware behind. We needed to remove it and the two nuts securing the master cylinder to the firewall. Once it was removed, we just tossed it in the scrap pile. 31 Here’s a look at the new master cylinder and booster setup from CPP (P/N 7387BB4-11). It comes fully assembled with a new bracket to mount everything to the firewall. 32 The new bracket attached at six points on the firewall, so we drilled the top two holes. 33 We installed the assembly over the four existing studs. Getting to the mounting hardware behind the booster wasn’t difficult because they are studs. We made sure to install the two top bolts from inside the cowl to mimic the four lower studs. 34 Once the booster and master cylinder assembly were secured to the firewall, we finished the installation by reconnecting the factory brake lines. All that was left to do was bleed the brakes and head out for a test drive. Afterwards, the truck had no problem coming to a halt.
