    Exclamation Vibration while braking

    Assalam-o-Alaikum to all Pakwheelers,

    I have a problem regarding Suzuki Mehran E-II 2013. Whatever the speed is like say 40km/h or 100km/h, the car vibrates! It severely vibrates when it is on 80km/h or 100km/h. I can feel so much vibration in steering wheel while on these speeds. The vibration is only when braking otherwise the car is smooth. Mileage is about 19500kms on the odo.

    The things I have done so far are,
    Wheel Alignment
    Wheel Balancing (2 Times)
    Disk & Drum Brakes Tooling (2 Times)
    Checked all joints
    Checked OEM General Tires too, they are good enough for more 10k~15k kms.

    I am really much worried about this situation, please help me out! @Xulfiqar @capsat @SER_GTR @babarhyd

    Thanks in Advance,
    Abbas Ali Abbasi

    You can diagnose the problem with rims and tyres. Have them swapped with some friends ride and than have a drive if its all good than problem is with ur rims and tyres. If not than to alignment guys beside alibaba restaurant and tell them that even after alignment the car vibrates at given speeds...

    Else have ur gear box checked. I drove my friends euro 2 few days back and its gear was not smooth as it should be.

    Thank you babar bhai. I always go to Bismillah Alignment shop. Went there 5 times in March. Yes I did swap Dunlop Tires with Alloy Rims from a friend's car. Car was still vibrating like it used to be. Regarding gear box, gears are smooth. Gear oil was changed on initial tune-up of 1000kms. The gear oil was used of Zic.

    Vibration under braking primarily indicates warped discs. You car is new and this problem shouldn't have come this early. But it seems either you took the car out for a car wash right after a trip (spilling cold water on heated discs) OR the DISCS orginally came factory defected.

    Get the discs checked first.

    Unbalanced rims/tires vibrate during normal drive. Not just under braking.

    There is a little-bit I can say wobbling when I drive around 10-20km/h speed.
    So this little-bit can cause more vibration at big speeds?
    I don't know why but I have a higher doubt on brake discs. Although my mechanic told that the discs are fine after tooling.

    Could be a faulty tire. How old are your tires?

    If there is wobble at low speeds, it is going to increase with speed. Now this new highlight makes me advise you to switch your mechanic and Alignment guy, because it isnt that big a issue that is hard to pinpoint.

    First check discs, then check rims and tires. Isolate and then spend on rectification.

    Thank you so much. I will do everything as you advised. I am in Karachi right now, will go to Hyderabad in a day or two. Will go to Suzuki Dealership directly and will first check discs and then check rims and tires.

    If its only on braking than probably tooling has destroyed the original stuff. Why did u go for tooling so early bro..... Khair its done. Ask alignment guys to check for chassis bends or excel bend it is possible that these may be at fault

    2 Mechanics advised me to do so. Sadly now tooling is done. Yes I asked alignment guys about chassis bends and axle bends. No issue in them.

    Looks More Like A Base Manufacturing Fault......!! Have You Check Your Steering Ends And All Other Stuff........Even If You Check That...There's Possible Reason Car Still Do That....You Can Expect That From Pak Suzuki And Mehran .......Keeping Mileage In View....

    Best You Can Do Is Swap Tyres And Check.........

    Visit PS Service And Ask Them To Resolve It....

    Oh man o man just saw this thread and i was having the same issue with my brand new mehran.The car used to vibrate when i used to press the brake paddle.I changed the rims of my car ,i changed the tyres to yokohama ,155/r12/70 still the car used to vibrate ,i did the alignment/balancing still that car used to vibrate .. i did change the rotars in warranty from suzuki ,still the car vibrated on applying brakes ,3s monkeys couldnt rectify the problem.. i even checked the hubs if they were loose ,nothing was wrong.. i did was bought a brand new rotars and did the tooling stuff on the both sides ,the brand new rotars were provided by suzuki.I changed the brake leathers to the soft one its name was MK ..bought for 4 tyres.. the brake leather provided by suzuki are of third class quality ,they are very hard .. the tooling on the both sides and the change of leather to softer one pads removed the problem alltogether.Dont fall for something else.. check wheel HUBS , tool the rotars of both sides and change the 4 wheel leather to MK brand.Even the new rotars provided by suzuki are also palraay.

    Machining or tooling as it is called here of Discs is a BAD idea. They do it here in Pakistan at the drop of a hat. I have owned cars in other countries and once the disc is grooved to a certain degree the discs are REPLACED. Machining the disc reduces its life by making it thinner. Both BMW and Mercedes (cars I have experience of) recommend REPLACEMENT not MACHINING. If there is no way out and you have your back to the wall, put a dial gauge to and check the run-out. Then take a micrometer to it and check the thickness at various locations and then check the min allowed thickness of the disc. Then decide how much material will be removed after the machining and will that result in the disc still being within the min allowable thickness.

    At the moment the car in my stable with the highest mileage is my faithful Kia Spectra with 175,000 km. Bought it brand new in 2003. Never had any machining to the discs and it is on it is on its fourth set of pads. I just have the pads replaced - NO MACHINING of discs despite my mechanic itching to do so. The new pads bed in within the first 50 km or so.

    I know the machining aka tooling isnt good for the pad health but how on the earth will he get the new pair without defect? I bought a brand new pair and they too were palraay..Suzuki themself provide you defected pair and once you get it you cannot return, what can we expect living down in pakistan.

    enough is said to understand it as ' manufacturing defect ' PS is not ready to accept & rectify. Tooling is not right approach
