disc brakes vs drums

[ozcity]

baka yung position lang ng mga brake shoe inside ng drums?

thanks ungas

Er... back in 1998, when toyota joined the subic races for that year with the AE111, they didn't finished the races because both cars ended up with brake failure somewhere in the middle of the race (overheated the brake system???).

baka nga brake shoes yan, leading shoe and trailing shoe

[pajerokid]

mazda2.... EBD or ABS yung nasubukan mo? :D

To increase braking power in my dad's terrano, we changed the hydrovac to that of the Patrol :D Boom! instant increase in brake power.

anyways, all my rides have four wheel discs. Except for the pajero which has drum in discs for the rear. Even if mas kaunti ang braking load for the rears, i still wont trade my discs for drums.

Naw... you can't be serious?! Is there such a thing as leading and trailing brake shoe? :whoa:

[mbt]

leading shoe = shoe closer to the front wheel, trailing shoe = shoe closer to the rear bumper...? dalawa kasi yung brake shoes na kumakagat sa drum diba?

[Ungas]

Yeah I get your point, but what's their point in placing the leading and trailing? All brake drums have 2 brake shoes in it.

sa marketing brochure ba galing yun? sometimes, the marketing peeps say the strangest things haha :D

[Ungas]

Yep! Kala ko nga bagong braking system or something that I should know. Tagal ko na gusto itanong kung ano nga meron dun , lagi ko lang nalilimutan, hehehe.

Ungas,

Kung yung shock absorber nga nilalagyan pa ng 'dual-action, telescopic ek ek', malamang hindi din makakaligtas ang brakes. hehehe. Mga tiga-marketing talaga. Minsan hindi ko alam kung nagpapatawa. :D

I guess some of the spin doctors at the marketing department is trying to make it sound like a twin caliper disc brake system. :D

the rear brakes only provide about 5% or 10% to the overall braking ability of the vehicle... the lion's share of the job is on the front brakes, so econocars can get away with rear drums with little loss in function

10% to 40% po yata ang kaya ng rear brakes.

To answer the question, depende sa model nung drum brakes. The current rear drum brake systems on today's cars would provide better stopping performance than the front disc setups of the '70s. And today's front disc brakes are truly exceptional in terms of stopping power. Combined with the fact that between 60 and 90 percent of a vehicle's stopping power comes from the front wheels, it's clear that a well-designed, modern drum brake is all that's required for most rear wheel brake duty. Lamang lang talaga ang disc brakes dahil fully exposed sila sa outside air. This exposure works to constantly cool the rotor, greatly reducing its tendency to overheat or cause fading which is the only flaw I could think of para sa drum brakes. Under high braking conditions, like descending a steep hill with a heavy load or repeated high-speed slow downs, drum brakes would often fade and lose effectiveness. Usually this fading was the result of too much heat build-up within the drum.

IMO, mas maganda sa karera kung naka disc brakes ka. Racers with disc brake systems could carry their speed "deeper" into a corner and apply greater braking force at the last possible second without overheating the components.

I think Drums Brakes have a more Tendency to Fade But Disc Brakes due to open air exposure reduces Fading..and More Biting power...
