Annoying problem while braking.. - Team-BHP

ashthedivx · 23rd April 2008, 22:42

Recently i had a delhi-shahranpur tour on my chevy optra, i faced some issues which sounded new to me..

a) High tyre noice while driving at high speed is too high, didn't noticed it too much before - Any solutions, apart from changing the tyres ?

b) Their was strange wobel sound from backside i.e. back tyres while braking from high speed, which certainly reduces comfortability level while braking - Is it something to do with proper alignment ??

I usually drive at high speeds, so i need to sort out these particular issues so as to make myself comfortable at braking during high speeds.

Try changing tyres like front to the back or left to the right. I was getting similar problem in my Elantra. Now its been fixed by doing this itself.

Does the wobble/vibration while braking from high speed also get transferred to the steering wheel. If yes, you need to replace the brake rotors/disks.

Tyre noise can also be due to stones being attached to the grooves, please check. Otherwise its a characteristic of the tyre (either by design or by usage) needing replacement.

Tyre noise could be normal for the tyres that your run. If you feel it is abnormal, check your tyre pressures. Tyres can get noisy if pressures are too low. Apart from this, the only solution is a tyre change.

Apart from the suggestions so far, check alignment+wheel balancing. Get your brakes serviced. Are you using after-market alloys? These could cause vibrations while braking from high speed, if the specs are not OK. Check your wheels for any damage/bends (especially if they are stock steel rims). This could cause vibrations while braking.

Check your tyres for damage/tread wear/flat spots and replace if necessary.

Prajesh,

I am running on Bridgestone. Not sure the series name.
So far they have done around 20K km as they got changed by my cousin to whom car was lended in that particular period, Rent was free tyres

Will give a try to tyre rotation this weekend. Which tyres your elantra is having.

No, it doesn't but the strange sound looks like something like... thud..thud... thud....

I usually maintain a tyre pressure of 34-PSI at front and 32-PSI in rear, i hope it is correct for chevy optra. Earlier i use to keep 32-PSI in front and 30-PSI in rear, which resulted in low pickup and heavy moving. Upgrading the tyre pressure helped in avoiding such problem.

I am on stock rims, i am too even somehow inclined towards getting the alignments and balancing re-done which was initially done in showroom at the time of service around 4K kms back.

Rear tyres were checked for the damages and punctures on last weekend only, as this week's tour was in cards from last month. Tyres were fine without any damage or flat spot.

It was very much recent, like 2 week back i was getting this problem then after that i havnt faced this problem. Car is rock steady above 170 kmph too. This set of tyres had done just 9k KM.

Also, check the car's alignement and wheel balancing and before doing it ask them to rotate the tyres accordingly.

Got the rear wheel alignment and tyre rotation yesterday, problem seems to be solved

Rear wheel alignment was too much out, according to the tyre guy!!

Though the guy has asked to get the drum checked as an precautionary measure.
