Brake pedal push down all the way

[E-Jazz]

Hi all,

 

Just to check, I am now in my break in period at about 800km going for my 1000km servicing soon.

 

For the past 2 days, I realized that my brake pedal depresses quite easily down all the way to get enough braking action. Previously it wasn't that easy to press down. In fact, for the first 700km, the brakes have been quite hard all the way. Its only for the past 2 days it became very easy to press down all the way.

 

But today, it when back to the old hardness again. Not sure if this is normal during a break in period. Please advise. Thanks

aiya..just drive lah.all cars have different characteristic.You worried too much already.700km the brake pad still new,worry so much for what?if need to depress more,then depress more lor.what's the issue seriously?All this is about feel and instinct,don't tell me ask you to drive another car,you also depress the same way you depress your car brake?and you think the car will stop the way your car will stop?Just move on pls.

check for brake fluid leakage, one of first signs of leakage is that there is little or no resistance when pressing down on brake pedal. bring to workshop for a detailed check, and please don't scrimp on brakes.

 

also, ignore previous poster - probably trolling or has no concept of the importance of well maintained brakes or safety.

friend.go and read properly,he said happen for 1 day only.the next day return to normal.I always check my own brake and brake fluid,it's perfectly normal for car brake to feel softer and after wash,it'll feel more grip,but only last when the car get out of carpark.

new not always means perfect condition. get it checked since under warranty.

more important is when you said "press down all the way", but does it still brake or no brake at all?

 

if no brake then it is quite a conern

I experienced the same thing in my new city as well, except that the pedal doesn't go back to being hard. I feedback the issue to KM during the 1k servicing but they claim nothing leaking and is normal. I'm going to try bleeding the brakes to see if it helps.

 

Just to clarify, theres nothing wrong with the braking power. Its just spongy pedal. The problem happened after I did e-braking.

feedback to Kah during first service

possible vacumn leak

 

[Passion]

My suggestion is to try keep pumping the brake pedal.Check if your brake fluid went down.If not,then it's not leaking.Before pumping,pls check whether the fluid level is at the recommended level a not.If not,confirm leaking.Brake leaking will lead to lose of brake effectiveness.But since thread starter doesn't always encounter the lose of braking power,but only soft brake,it could means there's air or water in the brake system. Once the air/water move out from the brake system,the normal hardness come back.Am I right to say so?

Shouldn't vacuum leak cause a harder pedal as no vacuum means no brake boost?

[Furrynadz]

rephrase, leak in vacumn line

Hi Passion,

 

With all due respect, I personally feel that brake itself is of utmost importance regarding driving on the road as I believe in driving responsibly, safely and it is also fair that others deserve to reach home safely to their families like I do.

 

So far I became concern cause every article I read reminds me about importance of tyre and brake maintenance.

 

So do pardon me for the newbie post hehe.

 

no hard feelings.

 

One key thing you have mentioned I think is washing. During these 2 days when I had this problem, the road was extremely wet followed by heavy rain whereever I go. Also another bro/sis mentioned about E-braking which I performed once when one guy just turned out of the minor road without checking main road traffic. I'll monitor again and see how it goes.

Will note the pumping part. Thanks for bringing that up. So far I have checked on the fluid level, it seems okay. I suspect like what you mentioned, air or water in the brake system. Thanks =)

I prefer good resistance when stepping on the brake. The low resistance just means having to step further, personally I don't like it. So far, I have driven toyota, hyundai, civics, city and so on. Out of all of it, I still prefer the initial jazz pendal sensitivity and resistance. Hopefully it will remain haha.

 

No worries about previous poster, I'm cool with it. Yea agree on the importance of brakes and safety.

 

Thanks bro.

Understood. Thanks =) I going for 1 k servicing soon. So in the mean time, I'll drive slower and monitor.

Before this incident, pressing little bit of brake is met with high resistance which also produces good braking power.

 

Now, it is more like pressing a little produces little braking power, but still have a bit, but when you press down further, the breaking power will kick in more but given that the brake pedal can be so soft and easily push down, it requires good soft stepping control to come to a smooth stop without feeling the braking jerk.

 

So thats the part I am slightly uncomfortable with. I prefer coming to a smooth stop without feeling the effects of even braking.

Yea, I also did an E-brake recently. Bro, do let me know when you are done with bleeding and whether it helps.

 

Thanks in advance.

Yea, i read about this part too on the online articles, some also say possible master cylinder but thats for older cars. New cars less likely.

friend,after driving for sometime,it'll turn jelly again.Can't maintain one.But for your case,go for check up better.

[Yeobh]

The main cause is usually moisture getting into the system and during hot days with too many stops and drive conditions, the moisture starts to boil and cause formation of air bubbles in the system. In our climate brake fluid normally will loose its performance within two years. Yr mech will only use their eyes to inspect but without a proper moisture tester they cannot 100% confirm the status of the break fluid condition.

[XALmoN]

sounds like bubbles, a rebleed should do.

I see, okay, will be calling my agent shortly to arrange for appointment. Just hit 900km today. So I guess its time to schedule the 1k oil change appointment as well.

 

The only thing I realize is that these days, there is no more 1k, 5k (semi syn), 10k etc old change.

 

Instead its 1k, straight away next one is 10k and 20k. They skipped the 5k semi synthetic oil change from what I know these days.

I see, thanks for the info.

 

I guess it doesn't harm to do an oil change completely once every 2 years or so. In between the 2 years are there any need to top up? or is the existing always enough for about first 2 years?

Yea, I guess so too. But yesterday till today, things went back to normal. Pedal feels resistance, braking is as though I got the car on day one.
