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.
