Know The Brake Master Cylinder of Your Vehicle Better

 

What is Brake Master Cylinder?

• The brake master cylinder converts the mechanical pressure on the brake pedal to hydraulic pressure.
• It feeds fluid into the brake circuit controlling with mechanical force. 
• Both disk brake and drum brake have master brake cylinders. 
• For statutory provisions cars, come with two brake circuits.
• The Brake Master Cylinder generates hydraulic pressure for the two separate brake circuits. 
• In the event of one brake circuit failing, the pressure on the brake increases. 
• The driver presses the brake pedal, the power from the foot is transferred to the pedal and transmitted to the pressure piston. The piston moves towards the brake line. 
• In old vehicles, the piston collar moves over to the compensating bore, closing the pressure chamber and forcing action from the brake. 
• With the release of the brake pedal, the spring supported pressure piston returns to its original position. The brake fluid flows to the main cylinder with another press of the pedal the brake pressure increases.
• The new vehicles Electronic Stability Program (ESP) are without compensating bores and replenishment ports. 
• The ESPs tasks are performed by the central valves. 
• If the master brake is neutrally positioned, the central valve opens. 
• The replenishment port and the bore position compensate for the volume between the brake fluid reservoir and wheel brake. 
• When the brake is in use the central valve closes preventing the connection between the brake fluid reservoir and wheel brake. 
• The pressure begins to build as the central valve closes, which is like the primary collar passing over the compensating bore in a master brake cylinder with a similar bore.

The main parts Brake Master Cylinder

• Brake Master Cylinder is a hydraulic pump and the heart of the hydraulic braking system. 
• It has two main parts, the fluid reservoir & the piston.
• The reservoir which holds the brake fluid compensates for the change in fluid volume in the pipelines from temperature variation and leakage.  
• To stop leakage rubber seals are installed at both ends of the piston in the compression chamber. 
• The piston with reduced diameter is always surrounded by fluid. 
• The pushrod is covered with a rubber boot to prevent dirt from entering the brake line sides of the compression chamber.
• The fluid check value with a rubber cup retains the residual brake pressure when the brake is released.
  

When is brake master cylinder replacement needed?

• The seals in the master cylinder dry out, turn brittle and lead to leakage.
• Overuse of the brake wear off the master brake cylinder and needs replacement. 
• If the master cylinder fails lookout for the signals, the brake light will be on.
• Notice brake fluid leaks.
• Braking is soft and springy.
• It takes greater effort to halt the motor.
• The brake fluid level is lower than normal.

What to check before buying a used brake master cylinder?

• Open the brake fluid reservoir on top of your master cylinder. If it is a metal reservoir, use a screwdriver to check the retaining clamp placed at the top. 
• The cups should touch the surface of the brake fluid and are pushed up when there is full fluid preventing evaporation while keeping dust and dirt away. The brake fluid should maintain the full line of the cylinder side or 1/2 inch of each chamber.
• Carefully look for strain marks, wetness, gunk. Look for leaking signs.

When And Why Should You Replace Your Car AC Compressor?

 

• AC compressor is the most important part of the air-conditioning unit.
• The Car AC Compressor ensures that the unit works effectively while playing a major role in cooling.
• The compressor puts necessary pressure on the refrigerant and activates its heat transfer characteristic to change the temperature.  Keeping the insides of the car cool in the hot summer months.

What are the parts and variations of a car AC Compressor?

• The compressor has two ports, an inlet/ suction and an outlet/discharge port.
• The housing includes the compressor inlet duct, inlet for compressor wheel, oil filter and valves, refrigerant pipe connections and the connecting points. The pulley with the electromagnetic clutch.
• Compressions have different variations and though they perform the same job, they work in different ways.
• The Reciprocating AC compressor.
• The Scroll or SpiralAC compressor. 
• The Screw AC compressor.
• Rotary vane AC compressor.
• Centrifugal AC compressor.
• Compressors found in electrically driven vehicles, hybrid vehicles.
  

How does the car AC Compressor work?

• The AC compressor compresses the refrigerant when the engine is propelled. 
• The heat is absorbed from inside the vehicle cabin. 
• The compressor is driven by the pulley or V-belt in swashplate compressors, the commonly used compressor type. It is attached to the engine. 
• The six double-ended pistons responsible for intake and compressions oscillates as the AC switch is pushed and the electromagnetic clutch sets the belt drive in motion. 
• The reed valve regulates the refrigerant flow which mixes with a thin mist of oil to lubricate the moving parts. 
• As the AC Compressor takes the gas from the refrigerant, the pressure drops with evaporation. 
• The refringent evaporates at a lower temperature and the AC compressor takes that cold vapor to compress it. 
• The refrigerant gas is warmed during this compression and moves through pipes in the condenser. 
• The gas reliquefies and moves to the cooling area, the refrigerant absorbs heat from the cabin changing to a gaseous state and is sucked by the AC compressor.
  

Signs for replacement of a car AC compressor

• The first sign is that the AC is not cooling as efficiently as it did before. If the compressor is damaged, it cannot regulate the refrigerant flow properly. 
• Loud noises when the AC is switched on.
• If the car clutch breaks or fails to work, the compressor does not receive enough engine power. 
• Check the vents for obstruction, the cabin air and filter clogging can lead to imperfection in airflow. 
• AC compressors are difficult to repair, and replacement is the best option. 
• Check the fuse before you decide on a replacement. 
• A malfunction in the AC compressor can lead to refrigerant leaks. Look out for leaks.
  

What to check when buying a used AC compressor?

• Make sure that the drier and orifice tube is replaced.
• Replace the condenser/TXV and flush all the lines and evaporator core.
• It is hard to flush the condenser, but make sure the metal is washed out thoroughly as you do not want metal parts to run back on the compressor, which will cause failure again.

Things to Check before buying Transmission

 

Driving in stop-and-go traffic for an extended period of idling the vehicle too long, driving off-road can lead to a breakage in the transmission. Transmission is an indispensable part of the vehicle as it multiplies the engine torque and propels the weight of the vehicle. Responsible for stress-free driving, improper operation of the transmission can lead to its failure.

Know where you could be going wrong?

Vehicle overheating

Automatic transmissions can operate at a maximum of 200 degrees. When you go beyond this limit by every 20 degrees you are risking the life of your transmission.

Dropping of fluid level 

If you do not maintain the fluid level which cools the internal components in the transmission, this leads to overheating and failure of the transmission. 

Fluid Needs Change

Transmission fluid also becomes dirty like the engine fluid and needs to be changed. Dirty fluid can also lead to overheating and failure of gaskets and seals. 

Incorrect fluid

Follow the automobile manual to know which mobile type is suitable for your vehicle. The fluid should not be mixed with other fluids as that would harm your transmission. 

Let the transmission cool

Allow your transmission to cool, give your automobile rest. The transmission overheats if not allowed to cool for at least a few hours. 

Start Stop gradually. 

While driving do not abruptly start or stop your vehicle. Start the engine and once heated take off gradually in the first gear and then graduate to more. The same should be followed while bringing the vehicle to a halt. 

Forced brake

When the vehicle is on high RPM a forced downshift can cause excessive wear and tear on the clutch and bands, the transmission components. 

Using shift lever to reverse when the engine is idle

When the engine is on the fast idle abrupt engagement of the transmission will lead to clutch, gear, bands, sets and driveline and engine and transmission failure. 

 

The price of an original transmission can be daunting while the used transmission is pocket friendly and if purchased on sale from a reliable source, it can last long. 

Things to Check before buying automatic used transmission.

• Check if the fluid looks or smells burnt.
• Pull the pan to see if there is a lot of clutch material on it.
• Check if transmission fluid looks dirty.
• Hold down the pedal brake with one foot, and step on the gas pedal with the other foot and rev up the engine while using parking brakes for a few seconds. If the engine cannot rev for long there may be some issues with the transmission.

Things to Check before buying manual used transmission.

• Put your transmission on first gear check the output shaft rotation speed as you turn on the input shaft.
• Shift to second gear once again change the output shaft transmission speed, notice carefully if the speed is slower than when it was in the first gear. 
• Subsequently, check all gears to check if the transmission is shifting gears properly. 
• Also, check if the performance matches your expectation.
• Put it on reverse gear to see if the output shaft counter spins. 
• Check for Odd sounds (whirring, squealing, bumping, or thumping), Grinding noise, Transmission jumps out of gear (into neutral), Difficulty shifting gears, Car stuck in one gear, Car that can't get into gear and Leaking transmission oil.
