CPP Electric Power Brake Booster & Master Cylinder Kit - 1988-1998 Chevy/GMC C1500

Ditch the vacuum-dependent factory brake booster headaches and upgrade to CPP's Electric Power Brake Booster & Master Cylinder Kit - a self-contained electric hydraulic booster system that delivers consistent, powerful brake assist regardless of engine vacuum, cam choice, or manifold vacuum drop from aftermarket intake work.

If you've ever swapped a cam, added forced induction, or run into inconsistent brake pedal feel because your engine's vacuum signal isn't what GM designed the factory booster around, you know exactly why this kit exists. An electric power brake system uses its own self-contained electric hydraulic pump instead of relying on engine vacuum, meaning your brake pedal feel stays completely consistent no matter what's happening at idle, under boost, or with a wild cam that kills vacuum at low RPM.

This is also the go-to solution for guys who've dropped the engine height, moved the firewall, or done other engine bay modifications that leave zero room for a bulky factory vacuum booster. The electric booster's compact packaging solves clearance problems that a traditional vacuum booster simply can't work around.

CPP includes a matched master cylinder sized correctly for your brake system, so you're not stuck guessing at bore sizes or sourcing a master cylinder separately - this is a complete, ready-to-install kit. Wiring is straightforward with a dedicated harness, and the unit runs off your truck's existing electrical system without requiring a separate battery or complex charging setup.

Installation replaces your factory booster and master cylinder as a unit at the factory firewall mounting location, though you'll need to run the electrical connections per CPP's included instructions. This is well within reach of anyone comfortable with basic brake system work and simple wiring.

Fits: Chevrolet C1500 1988-1998.
