| FAQ_Q10 | How can I identify my brake booster? |
| FAQ_Q4 | What causes multiple booster failure? |
| 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. |
| FAQ_Q5 | Why do my brake lights remain illuminated after installing my replacement brake booster? |
| 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_Q1 | What does a Brake booster do? |
| 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. |
| 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. |
| 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_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_Q6 | Can I use a brake booster from a different application? |
| FAQ_Q8 | Why is fluid present between my master cylinder and brake booster? |
| FAQ_Q9 | Why do I have less than 18 inches of vacuum supplied to my 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. |
| 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. |
| 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. |
| FAA_A6 | No, brake boosters are application specific. Most will have different master cylinder and firewall mounting spreads. |
