The main function of the brake master cylinder is to convert the mechanical force applied on the brake pedal into hydraulic pressure (brake fluid pressure).

Main Components:
• Reservoir – The place where brake fluid is stored.
• Inlet Port – The port that allows brake fluid to flow from the reservoir into the cylinder.
• Outlet Port – The port that sends brake fluid to the brake lines.
• Piston – The part that moves forward with the push rod and applies pressure on the brake fluid.
• Return Spring – Brings the piston back when the pedal is released.
• Seal – Prevents brake fluid leakage.
• Push Rod – Connects to the brake pedal and transmits force to the piston.

Operation:
1. When the driver presses the brake pedal, the push rod applies force on the piston.
2. As the piston moves forward, the brake fluid is forced out through the outlet port into the brake lines.
3. This pressure is transferred to the wheel cylinders/calipers, which activate the brake pads or shoes to produce friction force.
4. When the pedal is released, the return spring pushes the piston back, and the fluid returns to the reservoir.

මෙහි මුලික කාර්යය වන්නේ බ්‍රේක් පෑඩලය ඔබන විට ඇති වන mechanical බලය, hydraulic පීඩනයකට (brake fluid pressure) පරිවර්තනය කිරීමයි.

මුලික කොටස්:
• Reservoir – Brake fluid එක ගබඩා කරන ස්ථානය.
• Inlet Port – Reservoir එකේ brake fluid, cylinder එකට ගෙනියන ද්වාරය.
• Outlet Port – Brake fluid, brake lines වෙත යවන ද්වාරය.
• Piston – Push rod එක මගින් ගමන් කර brake fluid එකට පීඩනය දෙන කොටස.
• Return Spring – Pedal එක අතහැරූ විට piston එක ආපසු ගෙන එන දේ.
• Seal – Brake fluid leakage වීම වැලැක්වීම.
• Push Rod – Brake pedal එකට සම්බන්ධ වී piston එකට බලය සම්ප්‍රේෂණය කරන කොටස.

කාර්යය:
1. ධාවකයා brake pedal එක ඔබන විට push rod එක piston එක මත බල දේ.
2. Piston එක ඉදිරියට ගමන් කිරීමෙන් brake fluid එක outlet port හරහා brake lines වෙත යයි.
3. එම පීඩනය wheel cylinders/ calipers වෙත ගොස් brake pads හෝ shoes ක්‍රියාත්මක කර ගාස්තු බලය (friction force) නිපදවයි.
4. Pedal එක අතහැරූ විට return spring එක piston එක ආපසු ගෙන එයි, fluid එක නැවත reservoir එකට යයි.

කෙටි විස්තරය :-
“Brake master cylinder එක තමයි brake system එකේ හදවත.
ඔයා brake pedal එක ඔබන විට push rod එක piston එක ගමන් කර fluid pressure එක හැදෙනවා.
එය brake lines හරහා wheel වලට ගොස් brake pads discs වලට යටපත් කරයි.
Pedal එක අතහැරියම return spring එක piston එක ආපසු ගෙන fluid එක reservoir එකට යවනවා.”

முதன்மை செயல்:

பிரேக் பெடலை அழுத்தும் போது உருவாகும் mechanical force ஐ hydraulic pressure (brake fluid pressure) ஆக மாற்றுவதே Brake Master Cylinder இன் முக்கிய பணி.

முக்கிய பகுதிகள்:
• Reservoir – Brake fluid சேமித்து வைக்கும் இடம்.
• Inlet Port – Reservoir இலிருந்து brake fluid ஐ cylinder க்கு அனுப்பும் துவாரம்.
• Outlet Port – Brake fluid ஐ brake lines க்கு அனுப்பும் துவாரம்.
• Piston – Push rod மூலம் நகர்ந்து brake fluid மீது அழுத்தம் கொடுக்கும் பகுதி.
• Return Spring – Pedal ஐ விடும் போது piston ஐ மீண்டும் கொண்டு வரும் spring.
• Seal – Brake fluid கசியாமல் தடுக்கிறது.
• Push Rod – Brake pedal இன் சக்தியை piston க்கு அனுப்பும் பகுதி.

செயல் முறை:
1. ஓட்டுனர் brake pedal ஐ அழுத்தும் போது push rod, piston மீது அழுத்தம் கொடுக்கும்.
2. Piston முன்னோக்கி நகரும் போது brake fluid, outlet port வழியாக brake lines க்கு செல்கிறது.
3. அந்த அழுத்தம் wheel cylinders / calipers க்கு சென்றடைந்து brake pads அல்லது shoes செயல்பட்டு உராய்வு சக்தி (friction force) உண்டாகிறது.
4. Pedal ஐ விடும் போது return spring, piston ஐ மீண்டும் இழுத்து கொண்டு வந்து fluid மீண்டும் reservoir க்கு செல்கிறது.
