Stand on the brake pedal and you should come to a screeching halt. If it's taking too much leg muscle to scrub off speed, your Jeep Wrangler brake booster could be bad. Without power assist, emergency stops are dangerously prolonged and fine control necessary for off-road driving is impossible. Restore your braking with our replacement parts.

Avoiding Driver Fatigue
Puttering around town is easy, but driving down backcountry trails demands more physical effort. Your power assist systems for your steering and braking keep your Jeep under control. If you are depending on manual controls, you will need to drive slower and invest more of your personal strength.  

Even with a good working brake booster and master cylinder, you still wear yourself out after a day of off-road driving. Tired legs do not react as fast to emergencies and accidents are more likely. Upgrades to your braking take the heavy work out of stopping your Jeep and keep you fresh for the whole day.

How Your Brake Booster Works
A vacuum assisted Jeep JK brake booster depends on a properly sealed system and a strong running engine. Boosters are mounted inline between your brake pedal and your master cylinder. They look like a big metal drum. Inside, a heavy rubber diaphragm seals off two sides of the chamber. Through a fitted hose and valve, manifold vacuum pressure is applied to the booster's diaphragm.

Tap your brake pedal, and the valve opens to apply vacuum at the diaphragm. This does most of the work of depressing your brakes for you. Worn rubber components allow leaks that inhibit the booster's function. In extreme circumstances, a faulty booster can even cause your engine to stall.
