Some people tend to take their brake systems for
granted, and don’t think much about it until there is a
problem. I on the other hand tend to have the opposite
opinion. As much as I like to go fast, I really like being
able to stop.
Brake systems are actually pretty simple. The system works
on the principle of hydraulics, and the incompressibility of
brake fluid, with a combination of parts to do the actual
work. But, the correct combination of parts working properly
is what makes for a good brake system. Remember, not all
parts are the same. What looks the same on the outside can
be totally different on the inside. With this in mind, we
with the help of our friends from Master Power Brakes are
doing a series on troubleshooting your brake system. Our
goal is to give you a systematic way to check the various
components of your brake system to diagnose or rule out a
problem with those components. Hopefully, leaving you with a
brake system that works correctly so you can enjoy driving
your car, and be safe at the same time.
We are going to start with brake boosters and pedal ratios.
If you have power brakes, you have a brake booster. There
are four main factors that can affect the performance of
your power brake booster. There can be a problem with the
booster itself, the amount of engine vacuum available, the
check valve, or with the pedal ratio. Any one of these can
cause your power brake system to have a hard pedal and poor
braking. For a step-by-step explanation on checking your
power booster click on the following pdf file.
Pedal ratio is important whether you have power or manual
brakes. Too high a pedal ratio with power brakes can cause
overly sensitive brakes. Too low a pedal ratio will cause a
hard pedal and poor braking. The same is true with manual
brakes, although too high a pedal ratio is rarely a problem.

ratio just click on the following pdf file.
