Brake Master Cylinder is an important part of braking system of GMC Sonoma and its function is to amplify the force exerted by the driver's foot into hydraulic pressure. This mechanism works through forcing the fluid to flow through the system to the slave cylinders which in turn play a role in making the brakes to operate and hence produce the necessary friction to halt the vehicle. In most cases, master cylinder fixed on the front of vacuum power booster with or without internal and external fluid tank. In years past GMC Sonoma vehicles have used dual circuit master cylinders; if one circuit goes out the other can still supply the brake power. This design makes operation safe by achieving a level of autonomy where the machine can keep operating if the hydraulic system is compromised. Some common problems with the Brake Master Cylinder are the leakage of the fluid, problems with aeration and internal failure, all of which may result in poor braking system. Routine check up's for signs of leakage or moisture is crucial to the durability of the braking system.
