The design of the power brakes on your Accord or Civic, along with the Honda brake booster that powers them, dates back to the early days of the automobile. But not all Hondas have a Honda brake booster: Some of the first models used manual brakes since the cars were so lightweight. With the current Civic weighing in at roughly the same as a 1980s Accord, finding a Honda without a Honda brake booster is pretty much impossible these days, and the Honda brake booster has also become an integral part of the antilock braking system. But what does the Honda brake booster really do, and why are you facing a Honda brake booster replacement? In a nutshell, the Honda brake booster acts as an amplifier of sorts, but it works off engine vacuum rather than electricity. When you step on the brake pedal you actually press on your Honda brake booster. The Honda brake booster then amplifies the pedal pressure and exerts far more pressure on the brake master cylinder, stopping your car. The whole system is really very elegant, but it all depends on one thing: vacuum. If your Honda brake booster can't receive vacuum due to cracked or missing lines from the engine, or if the Honda brake booster has internal damage that prevents it from holding a vacuum signal, you'll end up with the dreaded hard pedal and a car that's extremely difficult to stop. Needless to say, a bad Honda brake booster isn't the kind of repair you can put off until you save up some money-anything like a Honda brake booster that interferes with how well you can stop your car needs to be dealt with immediately.
