Brake "Problem"
« on: July 27, 2008, 11:39:15 AM »
More recently, my 2-year old latio (CVT) started to emit sound when braking..like "e e e e e..."...Esp bad when reversing..

I sent my car to TC for servicing and they claimed there is nothing wrong with the brake system. Brake pads everything ok.
Not convinced by the answer, I asked again anyway to resolve the problem once and for all, they claimed that it is brake dust that caused the sound..

Seriously, I am still not convinced given that they just service the car and the problem came back within less than a week. Everytime you ask, they give the same answer but not solution  :mad:

I hardly see (or hear) other cars emitting such sound most of the time.  Also, for the past 2 years, my car don't give such problem..Furthermore, I have been regularly sending my car for maintenance in accordance to the schedule time table. I just wonder whether I have to send my car to TC every week to service the brake ! :confused1:

Not sure if anyone can advise on this?  I hope to identify the root of the problem and resolve it..

Thanks in advance

What is wrong with them? Are their Customer Service that bad??? What is the point of sending sms for reminder and all? Trying to impress or just following the protocol?

Which branch did you send your car for servicing? I went to Toa Payoh and Ubi before but so far they have been solving my problem esp with my suspension issue.

I went to the one at Toa Payoh.. Generally, I have no problem with the customer service and they are willing to look at your feedback on the problem.

However, in this instance, they can't offer a solution to this so-call problem.  I trust no one here will accept their explanation or that it is something the car owner need to live with it..

Hi, 3 possible causes
1) wheel assignment couldbe out ;
2) CVT oil need to change ;
3) brake disk lining is dirty

for 1 & 2 , check with TC
for 3 , can go htyre @bendemeer road
below is the desc of the service. hope it helps. cheers

Brake Disk Lining Cleaning System

BRAKE FLUID EXCHANGE: Brake fluid is hygroscopic; whereby it absorbs moisture from the atmosphere, usually through the master cylinder reservoir and permeable brake hoses, requiring regular service.

Moisture contamination lowers the boiling point of brake fluid. Even under ordinary driving conditions the contamination can cause the brake fluid to boil, releasing vapour in your brake system. When vapor is compressed inside the system one of the most dreaded driving crises - a dangerously low brake pedal or even no brake pedal could develop.

At the same time, when moisture contaminated brake fluid reaches high temperatures (450 to 500 degrees) an electrochemical reaction makes fluid highly acidic. This acid degrades the steel lines, rubber hoses, and can cause early failure of the cast iron and aluminum components in your brakes. Part of the H TYRE brake servicing is to exchange a new flush of brake fluid for your car using the multi-function EC-900C. This service will only set you back SGD$28. It's a small price to pay for the safety of you and your passengers!

BRAKE CLEANING: Most cars are equipped with brake sensors which send out signals when linings are worn to the point of needing replacement. However it is better to have a periodic brake check and have your brakes cleaned as hazardous dust, oil, grease and dirt deposit on the brakes over time. As all these harmful deposits reduce braking efficiency, at H TYRE, we have the WH-702 which loosens and removes these deposits ensuring smooth braking.Our responsible mechanics will have your brakes cleaned after the brake service.

Many problems can go undiscovered until total failure occurs.The best time to have your brakes checked and cleaned is during your routine tyre rotation and or wheel balance as the tyres must be removed for this service.

Could the sound be due to unevenly worn out front brake disc?

Grinding the discs to smoothen the surface might help.

Did the sound appear when braking at low speed?

I had the same problem, after servicing at TC Toa Payoh. Till today, I cannot accept that the brake rotor's surface was uneven. Explanation given was frequent braking and car wash. Initially, they skimmed the brake rotor. But I was unable to accept the work as I would not be able to skim again (if too thin) or when the same problem occurs after warranty period (who will pay). Eventually, they replaced a new brake rotor for me.

Did your problem go away after they replaced the brake disc rotor for you?

what? they actually SKIM your disk rotors? what a cheap job...
skimmed rotors, if skimmed badly, will cause more problem in the long run. this is what happened on my old car - the newly skimmed rotor worked great.. for about 10,000km before the same old problem came up

skimming makes the discs thin, thereby causing it to warp if under high temperatures or stress. depending on how good the skim job is, it can be over-skimmed

the latio discs are a little small for the size and weight of the car imho.. skimming it is really scary. i think a pair of brake discs cost like few hundred bucks. (last time i change a renault front disc pair is ~$400, jap car should be cheaper)

I always try not to follow too closely behind the car in front, as the Latio's small brake rotor and brake calipers, and its rear drum brakes are not as effective as a similar capacity car with front and rear disc brakes like the Toyota Vios.

Hi bro, any ideas or brands to recommend if we should change to a better brake system for our ride? Sounds like our ride very vulnerable especially if we have to e-brake in sudden situations... :ohmy:

Yes, for my car, it happened usually at low speed, eg when i park my car (most of the time during reversing).  Occasionally it will occured when you gradually depress the brake to a halt at traffic light or slope.

Disc rusty is it? If you go car wash after driving long distance it will help warp your brake disc faster too.
