Dear All,

Is it normal to have those squecking sound when you get in/out of the car from the suspension coil? I got this even when I first collected the car and has been wondering if this is normal. [:/]

 

A few friends had asked me this question and I am embarassed to tell them I dunno. [:/]

Have the same sound, it is the rubber piece attached to the oleo suspension. It is fluid there, possibly oil. If it is oil, you might want to check if there is a leak in your oleo.

 

As for mine,had brake fluid spilled onto it when removing the abs

Hi bro,

 

Is it some "gong..." sound which comes from the rear wheels? If so, fret not. That is because you have not pulled your handbrakes hard enough.

 

For our Superb, we usually pull the handbrake lever until the first or second click on level grounds to prevent unnecessary wear to the handbrake cable. The sound will be heard most clearly if you have passengers exiting or entering the car from the rear. In order not to hear the sound, please pull the handbrake lever until you can hear the 4th or 5th click.

Em...may be you are right. Will try it later. Sometime can hear it sometime don't. Yes, it is very prominent when passenger exit or enter the car from the rear.

 

Thanks

Just to share with you. Europeans usually do not apply the handbrakes when they park their rides on level roads. For those driving manual cars, they simply slot the gear to the first. For those driving auto ones, they shift the selector to 'P'. This is to reduce the wear and tear on the handbrake cable.

 

It is very important not to apply brakes, if possible, during winter. The handbrake cable can contract and it will be extremely difficult to release the handbrake.

Keep us updated of the outcome when you pull the handbrake lever until the 4th or 5th click can be heard. I am pretty confident that is able to eliminate the sound. But for the longetivity of the handbrake cable, just pull the handbrake slightly and bear with the sound.

Yes...you are right. The sound is gone when I pulled the handbrake hard enough. I have the habbit of pulling it with lever pressed so will not hear the click sound.

 

But what causes this?

When the handbrake lever is pulled until the first 2 clicks are heard, the rear brake pads do not bite onto the disc hard enough. As such, when there is movement (mainly vertical) brought about by the transfer of load (e.g. passengers alighting or entering the car), the rear brake pads will brush against the rear discs, causing the "gong...." sound.

 

Like I have mentioned, I am not bothered with this sound, as long as the car stays stationery.

This is OT actually...but I never had this problem when I was staying in Wisconsin, USA. Temperature can drop to -20 to -30 degree celcius during the night in the winter season but I never had any problems releasing my handbrake.

 

The only problem I encountered once was my car door frozen shut...keeping me out in the cold... [laugh]

Probably you need to factor in the duration which the handbrake has been applied. I recalled test driving a used Skoda Octavia TDI from a car distributor in Austria. The Octavia has been parked with the hand brakes applied for at least 2 weeks during winter.

 

Upon releasing the handbrake lever, one of the rear wheels was stuck. The car was subjected to several rounds of hard acceleration before the stuck wheel can be released. The handbrake cable was eventually replaced when I bought that Octavia. [;)]

Mazda 3 is having a similar problem and MM is changing all M3 that fitted with brake drum (rear) to brake disc FOC.

Hi,

 

You have cited the Mazda 3 having a similar problem. Do you know the root cause of it?

 

Is it due to a design flaw of the existing Mazda 3 rear drum brake which prompts Mazda to carry out the replacement FOC?

No idea don't bother to find out more. However I think it has to be a design flaw otherwise MM will not change the drum brake of all M3 on the road (the earlier batch) to disc brake. I got mine change and the problem gone.

From what I've gathered, seems it was more cost effective for MM to bring in parts/supplies for the disc brakes for all the Mz3s instead of stocking both the drums and the discs/calipers/pads etc. [;)]
