Question on engine break

[japeeps]

question about engine break... Nag caucause ba ito ng mas mabilis na wear and tear sa tranny and engine.
Sa manual kase it says better to use engine break than prolonge used of breaks or combination of both.

I usually go down sa parking from 7th floor of the parking building just in first gear, using 2nd gear sobeang bilis naman pag free wheel breaks naman. so perfect speed for me is just stay in 1st gear. I've been doing this for 2 years since nabili ko ung adventure ko.

^^^good job, tama yan sir. Mas safe at mas matipid sa gas. Ganyan din ako pagbumababa ng mataas na parking.

*Brake not break ;)

Engine braking is useful for me...

kala ko kanina break in yung topic , ganyan din driving habit ko, tipid sa gas and less gasgas sa gulong and brake pad

[matiase]

i believe engine brake is useful not only pag pababa, i do short engine brake din, pag curves, i keep my distance sa harap, then change 1 gear lower, causing a bit of brake ..... di na gagamit ng brakes, then, accelerate after the curve...... then quick change gear 1 higher.....

Question lang po... I talked to a mb mechanic fr. Abroad ang sabi nya yung mga modern diesel daw ngayon pag nag engine brake may auto shutoff ang fuel delivery... Is it true?

Ok parin ba ang engine braking kahit umaabot na ng 2500 rpm?

[miggymontero]

I also do engine brake.

Meron nga ba bad effect ito and safe rpm for engine brake?

yes, ang layo pa nyan sa RED line.

Eto din iniisip ko minsan, wala naman siguro bad effect,

Mas mura lang siguro magpalit ng brake pads compare sa na damage na tranny yun eh kung may bad effect nga sa engine braking.

Mas malaki masisira kung nag init ang preno at di kumagat...wasak auto mo..

yespo.
gas engines effect the engine brake thru the partial vacuum in the throttle system.
diesel engines do not have such vacuum. they generate engine brake by controlling the fuel delivery.

brake brake versus engine brake...
one speeds up brake pad wear. the other speeds up clutch disk wear..
but if you continually practice jackrabbit engine braking, you'll also speed up tranny and engine wear..

[japeeps]

Sorry sa title... nasanay na break kse masarap mag break sa office haha...

Sir Dr. D... question khit po ba downhill or pababa lang ng parking with constant speed will it still cause faster cluth disk wear?
I'm thinking kse na mas nakakatakot ung overheating ng brake kaysa sa pagnipis ng brake pads..

so it means po ba... we can save diesel when using engine brake as against po pag naka nuetral lang tayo?

[red_one]

anything excessive is bad. use engine braking only when you need to. use your brakes only when you need to. drive at the appropriate speed. as long as you do not abuse your car, then normal wear lang ang mangyayari and not excessive wear.

nanghinayang sa brake pad or brake shoe pero sa pressure plate at dics,release bearing hindi ...

kadalasan gamit ko lang engine brake pag pababa..tulad sa bundok..mahabang pababa..


kung sa parking lang galing sa taas kahit 10 flor pa hindi naman ganun kabilis magiinit or mag babaga ung braking system mo..

I believe the engine can take more punishment than all the brake pads of your car combined

The only drawback is more fuel burned due to higher rpm when an engine brake is engaged compared to going neutral

You can check for yourself by focusing on the tachometer. Higher rpm means more fuel burned

i remember many years ago...
an extremely hilly resort was using ford fieras as their service vehicles. the driver there said they replace clutch disks once a month..
