Changing master cylinder

Brake cylinders are part of the car’s braking system. When you press the brake pedal brake cylinders press the brake pads to the brake drum. As a result, friction process is created and the speed of the car decreases.

Common malfunctions

The most common malfunctions that occur in the master cylinder are wear in the piston bore and piston seal failure.

The brake system is a very important system of a car because it influences on a safe by riding. So anyone driver, who drives a car must to know how the brake system works.

The master cylinder is the heart of the brake system. When you press the brake pedal the master cylinder converts an exerted force into hydraulic pressure to apply the brakes.

Pedal pressing moves a push rod in the master cylinder. There are two pistons (primary and secondary) mounted on the push rod. They create pressure into the system and push the brake fluid through the brake lines to each of the brakes.

When you released the pedal, the spring returns the piston to its resting position.

Master cylinders have two separate hydraulic circuits having their own fluid reservoir and piston. If one circuit has a leak, the second circuit insures and provides braking to stop the car.

The most popular problems that occur in the master cylinder are wear in the piston bore and piston seal failure. The main symptom of a failing master cylinder is a slowly sinking brake pedal. To decide the problem you need to replace the master cylinder.

Lines of brake system

The steel lines of the brake system route hydraulic pressure to each brake to stop the car. Leaks in the brake system can be a reason when air enters the hydraulic system. As a result, increases the amount of pedal travel, because air is compressible.

Systematically check the fluid level in the master cylinder tank. Pay attention to a brake warning light that can show that you need to inspect the brake system to find the leak. Use only original details when replacing.

There are some leak points that you need to check: brake calipers, wheel cylinders, steel lines, and rubber brake.

Replacement Master Cylinder

Replacement master cylinder
  1. Ensure that mounting areas of the master cylinder and the pipe joints are free of damage and debris. Fluid leakage and improper hydraulic pressure may cause brake failure.
  2. Don`t allow dust? Dirt and debris to enter the master cylinder or reservoir tank. Internal damage may occur, resulting in fluid leakage and improper hydraulic pressure.
  3. Always use a new O`ring or gasket if required for installation. Ensure proper installation of the O-ring or gasket for proper sealing. Fluid leakage and improper hydraulic pressure may cause brake failure.
  4. Use grease on O-rings and gaskets before installation for proper sealing and installation. Grease will help seal and install the brake master cylinder correctly to ensure proper hydraulic pressure.
  5. Handle with care. Brake master cylinders are precision manufactured. Don`t drop or deform. Never use a damaged unit.
  6. Tighten bolts, nuts and screws and utilize the proper tools as specified by the service information. Damage of screws and threads may cause improper braking function.
  7. Use new brake fluid that is specified by the manufacturer`s service information. Bleed the air accordingly to release trapped air within the hydraulic system.
