Disc Brake vs Drum Brake

[kamotecueman]

anu ba pinag ka iba ng dalawa? at anu ang mas malakas na preno sa dalawa??

Mas maganda ang disc brakes...

kamotecue,
disc brakes are open brake systems where you can see the friction materials and the braking surface. drum brakes on the other hand is an enclosed system that requires the brake drum removal for inspetion. over the years when traffic gets worse every year requiring shorter stopping distances, prompted for a more effective yet faster reaction brake systems. the advantages of disc brakes are:
a: shorter stopping distances
b: ease of inspection and servicing
c: dries quicker when driven across flooded streets
d: never needs adjustment nor adjustment mechanisms that gets stuck
e: less chances of leaks
f: less chances of water intrusion
g: never requires dust cleaning compared to drum brakes

Disc brakes are generally considered superior to drum brakes for several reasons. First, they dissipate heat better (brakes work by converting motion energy to heat energy). Under severe usage, such as repeated hard stops or riding the brakes down a long incline, disc brakes take longer to lose effectiveness (a condition known as brake fade). Disc brakes also perform better in wet weather, because centrifugal force tends to fling water off the brake disc and keep it dry, whereas drum brakes will collect some water on the inside surface where the brake shoes contact the drums.

I am sure Drum Brakes have its advantages as well coz it is still being used for heavy duty applications such as on trucks and buses.

nels,
newer trucks made by machinen fabrik auschwitz nuremberg, mercedes benz, scania, renault, volvo and other european trucks and coaches now use disc brakes. i have not seen heavy trucks in europe using drum brakes for the las year and beyond.

Kasi mahal yung new tech. Same reason why madami pading taxi na nakanon-power steering. Mas advantageous naman ang power steering.

jut,
the question asked was which one is better not which one is cheaper or more expensive

I was referring to why the majority of the trucks and buses here use drum brakes, hence the quote.

Hmmm. Ah ok. That is good to hear.
Kailan kaya makakarating dito yang mga disc brakes for Trucks and Buses.

On another note, hindi ko ma-imagine how they implement a disc brake to a double-tire connected to a drive train.

nels,
it is not impossible, if they did with the main landing gear of the C-5 galaxy aircraft with 28 wheels, how much easier is it to put disc brakes on a rig with 18 wheels? it's proper engineering
