FAQ_Q1	What does a Brake booster do?
FAA_A1	A brake booster assists in pushing the master cylinder piston when the brakes are applied. This multiplies pedal force to decrease stopping distances.
FAQ_Q2	How much vacuum does a brake booster need?
FAA_A2	For proper functionality, a brake booster will need a consistent supply of 18-21 inches of vacuum.
FAQ_Q3	How can I test my brake booster for proper functionality?
FAA_A3	With the engine off, pump the brake pedal until it feels firm and hold. Then, start the engine and the pedal will sink slightly if the booster is operating properly.
FAQ_Q4	What causes multiple booster failure?
FAA_A4	Fuel and oil vapors can enter the vehicle’s PCV system. These vapors will prematurely deteriorate the brake booster’s internal diaphragm.
FAQ_Q5	Why do my brake lights remain illuminated after installing my replacement brake booster?
FAA_A5	After replacing a brake booster, it may be necessary to adjust the brake light switch. Some vehicles contain a one-time use brake light switch. In these cases, the brake light switch will need to be replaced.
FAQ_Q6	Can I use a brake booster from a different application?
FAA_A6	No, brake boosters are application specific. Most will have different master cylinder and firewall mounting spreads.
FAQ_Q7	What is brake pedal free play?
FAA_A7	Brake pedal free play is a measurement of how far the brake pedal moves before the master cylinder first begins engagement. Some vehicles will require an adjustment. Please refer to your vehicle’s service manual.
FAQ_Q8	Why is fluid present between my master cylinder and brake booster?
FAA_A8	This is due to a failing master cylinder piston seal. This will result in brake fluid entering and contaminating the brake booster. The master cylinder and brake booster will need to be replaced.
FAQ_Q9	Why do I have less than 18 inches of vacuum supplied to my brake booster?
FAA_A9	A common cause is a restricted vacuum hose. If the vacuum line is free flowing, there could be more extensive engine damage or wear. Engine vacuum also fluctuates based on altitude. Please refer to the O.E. specification for your vehicle.
FAQ_Q10	How can I identify my brake booster?
FAA_A10	The most common way to identify the brake booster is by the vehicle application. However, most brake boosters have a pedal rod identification number stamped on the end of the rod. This can helpful in identifying the correct replacement brake booster.
