A brake booster is nothing but an improved master cylinder setup- that is used in the vehicle’s braking system to reduce the amount of pressure required for braking. It is an additional advantage for the drivers- especially for those who are more physically impaired. A damaged brake booster can make it difficult for you to push the brake pedal, force your vehicle to take longer time to stop, and make the brake pedal stiff. Testing the brake booster will help you to determine the fault code and leave more possibility for on time replacement that is required for safe driving.
