City brakes discussion

[umertango]

**HI GUYS , I AM HAVING SOME ISSUE WITH MY CITY 2014 MANUAL , DONE 50K KMS , ON PETROL . I NEED YOUR HELP TO DIAGNOSE THE ISSUE.

THERE IS NOISE COMMING WHEN APPLYING BRAKES ON FRONT SIDE ,,, I WENT TO 3S AND THEY SAID YOU NEED TO CHANGE FRONT HUB , DISK AND DISK PAD ... AND THE REASON THEY GAVE WAS THAT YOU TAKE IT FOR WASH WHEN THE CAR IS HOT ,,, IT BRINGS CHNAGES IN METAL ..I WAS SO SHOCKED THAT AT 50K I HAVE TO INVEST AROUND 40 000 RS IN MAINTAINCE ,,, ANY WAYS I TOOK IT TO LOCAL MECHANIC AND DID A COMPETE CAR BRAKE SERVICE ... FOR SOME TIME NOISE GOES AWAY BUT IT COMES BACK AGAIN ,,, AND HE PUT A SCREW DRIVER ON THE PLATE ND TOLD ME TO LOOK THE DISK PLATE OF YOUR RIGHT SIDE IS MOVING IN LATERAL AXIS... ITS NOT EVEN ,,SO NOW I AM CONVICED THAT ITS NOT ISSUE OF BRAKE SERVICE BUT THERE IS ISSUE OF EITHE THE DISK BEING CHANGED IN SHAPE OR THE HUB ISSUE ,,,,
FEW MONTHS BACK I ALSO CHANGED THE FRONT WHEEL BEARINGS OF MY CAR FOR 10000 RS AND NOW I HAVE TO CHNAGE THE HUB AND ALL THE BRAKING SYSTEM ... WHAT IS YOUR iADVICE PEOPLE ... WHY WAS THE DISK (TAWA) rotataing in X axis ,,, what should i do ?

Dear Poster,
If your disk has some uneven lines or the disk have gone deshaped then you need to either change the disks or its better to get them tooled from the machinist. By applying thin tool the thickness of the disk will decrease but it will not make much of difference if its done for the very first time.
I agree if the disk comes in contact with the water (When they are hot) then certainly your disk rotors will get deshaped. Last question which should have been asked first, does your car steering vibrates on applying brakes on high speeds? If yes then they need to be tooled by the machinist

no the sterring does not vibrate ... actually the disk moves left right ... like have u ever seen a bicycle tire ... jun rim tera ho jata hy tou tire left right bhi move krta hy ..like that the disk is moving ... ub yeh pata nhn hub ka masla hy ya disk ka
