lost brakes for almost 10 seconds

[allen_the_great]

share ko lang scary experience ko kanina..

pauwi ako kanina from ateneo around 4pm, after ko magU turn sa may gate 3 ng ateneo, naisipan kong gamitin yung overdrive ng CRV (i regret this now). pagtapak ko sa accelerator, bilis umabante ng tsikot. nung aapak na ako ng break, biglang hindi gumana! tiningnan ko kung break pedal ba talaga yung tinatapakan ko, tama naman. tapak ako ng tapak, sobrang dinidiinan ko na ayaw pa din bumagal nung tsikot! naririnig ko parang na-jam ata yung gear e, kasi tuwing tinatapakan ko yung break, tumitigas yung pedal tas may weird na howl coming from the engine. tas sobrang nagpapanic na ako, tumitingin na ako kung saan ko pwede ibangga yung tsikot without hurting/hassling other motorists, nang bigla naisipan kong pindot-pindutin paulit ulit yung overdrive button, thank god bumalik yung break ko. whoo, big sigh of relief. (btw, i was running * around 55 kph at that time)

ano kaya nangyari sa break ko nun?

O/D On allows you to exceed a speed of 80km/hr if IIRC.
O/D Off doesn't on the other hand.

While I did not have the chance to use an A/T CRV, I do know at least what it is through our A/T Xwind XTO.

Our wrong interpretion then with O/D is that when it's lit on the dash, we thought initially that it meant we could go above 80... yun pala, pag wala sya sa dash. Ewan, whoever made that confusing light on the Xwind?

When the O/D is on, mabilis nga hatak ng tsikot gawa ng the function of O/D is for highway driving. Brakes could not stop the vehicle more quickly than when overdrive is set to off.

Why your brakes totally did not work for 10 seconds is what bothers me, you might have to bring it to the casa for an immediate check-up. Who knows what can happen next.

Hope this is an isolated issue though.

hmm diyan din ako nacoconfuse with the O/D function of the CRV e, coz same as your Xwind, may light indicator din sa gauges if naka-On yung O/D function or not. sa CRV, pag naka-ilaw ung indicator, nakasulat "O/D off" sa gauge. so meaning ba nun pag naka-ilaw ibig sabihin naka-off ung O/D?

coz AFAIK and through my experience na din with this CRV, whenever i choose to use the O/D function (meaning naka-ilaw ung light indicator), it seems na mas matagal ang rev ng engine sa lower gears, seems like sinasagad ng makina yung power sa lower gears before shifting to higher gears. (i may be wrong with this but ito yung experience ko with O/D sa CRV)

anyway, im planning to bring this to the casa na, but not until next week. try ko muna gamitin ulit bukas. (sana wala masamang mangyari sakin) still wondering what the hell happened to my brakes? damn.

The O/D shouldn't have anything to do with your brakes unless your CRV is drive by wire like some newer cars but AFAIK the CRV is not drive by wire. However, your transmission is electronically controlled as most A/T are now so there may have been a glitch with the system. Have a mechanic check the vehicle as to why you lost the brakes.

A lot of misconception about O/D on the previous post, O/D is simply a higher gear(similar 5th gear) so it's shouldn't allow you to accelerate any faster than if it was off. Since your CRV is a 4 speed A/T with the O/D on it allows your transmission to shift to 4th gear otherwise you are simply moving on the 3 gears available without O/D. You also shouldn't be using O/D going up a steep hill with a heavy load since it will strain and cause your transmission to get too hot. You should use O/D when on flat, downhill, otherwise normal road conditions since it is a higher gear and can save you gas because it allows your tranny to use all the gears available. The 1 and 2(sometimes 3 on 5 speeds) allows you to hold those specific gears when the lever is placed there otherwise in D the tranny shifts through all the gears as needed.

i agree with redorange, overdrive has nothing to do with your brake systems.

allen, wag mo na gamitin yung sasakyan mo - dalhin mo na agad sa casa (tow if possible). don't take any chances with your safety and the safety of others in the car or on the road with you.

[OTEP]

O/D simply means the CR-V will go into 4th gear. With O/D off, it only goes up to 3rd gear. Contrary to local belief, O/D is not some sort of turbo boost device that makes you go faster. O/D is designed to make the engine more economical because the higher gearing allows you to cruise at a lower rpm. You turn it off for specific situations (detailed in your owner's manual). That is why the idiot lamp illuminates when you turn it off. Otherwise, it is just left on.

When the service brakes don't work, you still have the parking brakes, shifting to a lower gear, or the last ditch effort of simply shutting off the ignition.

[bratski]

dagdag ko lang, pwede ring gamitin overdrive off when overtaking kasi instant kickdown sa 3rd ang transmission pag nasa 4th gear.other than that keep the overdrive on. (walang light sa dash). Delikado yang crv mo bro, pa service mo na agad baka maaksidente ka pa. transmission problem yan, malamang na stuck up accelerator mo when you put the o/d off kaya hindi kinaya ng brakes

[Galactus]

Whether OD is on or off, you can go above 80 kmh...as OTEP said, OD on simply means you can engage the highest gear, and it has absolutely nothing to do with the brakes

ALLEN HAVE YOUR CAR CHECKED BY THE CASA. THAT IS NOT SOME MINOR ISSUE. BRAKES SHOULD NOT FAIL IN ANY INSTANCE. OD OR NOT.

Overdrive light is on IF YOU TURN YOUR OVERDRIVE OFF. The simple reason is that the overdrive is supposed to be always on during normal driving. The car is alerting you to the fact that your overdrive is off ... that's why the light is on. Overdrive is a kind of electronic extra gear. It is (supposedly) designed to save fuel and increase the life of your transmission.

Yeza.

Now, about what happened to your brakes, that should not have anything to do with O/D. O/D being off might just slightly improve your acceleration at cruising speed by automatically shifting to a lower gear, and not from a standstill at that, but then that's still not turbo boost/NOS so you should still be able to haul your ride down. Something is incorrectly triggering your brakes not to bite/engage with the O/D off. Have it towed to the casa ASAP.

tanong ko lang when engaging OD on/ OD off... kailangan pa ba naka full stop ang car or kahit on high speed pwede ka mag OD... Yesterday na experience ko I was running 170km/hr.. ( just checking the wheel balance).. then bigla syang parang nag change ng gear (kumadyot) but still running on the same speed.. Does it mean I need to engage my Overdrive??

[ghosthunter]

have you checked your brake fluid level?... it could be you have low brake fluid level (or inadequate pressure). When you were pumping the brake pedal, pressure built up enough to stop the CRV.

Or you could have a bubble in your brake lines.

-sorry na-double post-

[batang_raon14]

Point taken po. But just wondering out:
How come when O/D is off when I was driving our XTO, the gear shifts at higher rpms and you can't go any farther than 80 km/hr? Torque seems to be higher din. So if it does only shift up to 3rd gear, then ba't iba ang hatak with compared to O/D on? Electronic adjustment by the ECU? Pag naka-off kasi parang kaya pang umovertake nun (sa xwind ah?), pero pag naka-on wala na talagang pagasa kahit diinan pa gas pedal to downshift.

Also, what then gives the feel na parang "dumudulas" ang brakes when you're braking when O/D is on? There were four who drove our XTO then including myself, and pag naka O/D on ramdam talaga na kelangan pang diinan ang brake pedal compared to when it's off. Kahit mabagal pa takbo.

And lastly, yup, misconception rin talaga na it's like a turbo boost device (personally, courtesy of the service advisors of Isuzu Alabang themselves ). May car mag na rin na nagsabi na "Shame that it's still slow even with turbo" or something like that. Well, for the least, that's why we opted a manual tranny on the Sportivo and I get to correct my interpretation of O/D. Salamat po!

Depending on the load on the tranny it should make shift adjustments as needed. Even if you don't have the O/D on it should still shift accordingly, i.e. if you floor the pedal to accelarate quickly your tranny will down shift if it needs to or up shift when needed. You can engage it while in motion and it won't matter you will just see the rpm go down a bit, maybe from 3000rpm to 2500rpm. When I went to LA from San Francisco I would turn it off going up the Grapevine because we would be climbing over 4000 feet and turn it on again going down.
Just keep in mind the tranny shifts depending on the load you put on it, step on it to pass other cars and let off when you want to cruise.

If you can't go faster than 80 with the O/D off then it could be the gearing limit for your vehicle. What rpm is the engine running at 80 and what is your redline? If you step on the skinny pedal with the O/D on as long as you are not already running at redline it should still downshift if it's at the highest gear. You may feel more torque with it off because you are running at a lower gear. As far as the braking does your vehicle use hydro-boost assist or vacuum assist for braking? Maybe there isn't enough pressure.

ang tanga naman ng car mag na yan :twak:

actually turning the o/d on creates the exact OPPOSITE effect than having a turbo. since the gearing is taller in overdrive, medyo mas mahina ang hatak (of course correctable by stomping on the go pedal and making the a/t kick down to a lower gear).

Red line is 5k, at 80kmh rpm is at 3K. With regards to braking po, not quite sure, vacuum assist perhaps? Hmm... if it is that bad, then xwind is really slow.

Yup, and kaya di ko na chief binanggit ung pangalan eh.

'di kaya nag fail temporarily yung vacuum ng hydroback assembly ng brake mo? kasi titigas talaga yung brake pedal kapag nawalan ng vacuum ang hydroback ass'y mo at saksakan ng hina ng brake tapak to the max talaga, though at one hand 'di dapat gano'n kabilis mawalan ng vacuum ang hydroback or maybe at some point nagkaro'n ng fault ang EBD pa check mo na sa kasa yan...

P.S.: 'di ba sa 2 fast 2 furious? 'di nakapreno ang skyline kasi na-static-gun yung auto? eh de-kuryente ang preno at naka EBD so 'di gumana ang EBD, 'di siya nakapreno...
