Weird whinning noise when braking specially in low speed

[far123]

Hi everyone noticed a weird kind of whinning noise coming when braking specially at low speed like 20 mph and also when accelerating from still till like 30mph then goes away kind of, can anyone please help and give me an idea of what it could be? would be greatly appreciated

[mivecrx]

Do you mean when actually pressing the brakes or just slowing down?

[far123]

when decreasing the speed and its a bit more when pressing the brake

Could be:

Wheel bearing

Front caliper or maybe pads.

Rise up the car, support it well and spin the wheel by hands, there should be no odd noises at all.

Update Your location please, maybe there someone in Your area that can look at it for U.

Thanks for your reply
Just took it for a drive to make sure
Noticed that it doesn't matter if I brake or not the noise is there actually at all time
I just noticed the noise after I changed my front tyres from 205/40/17 to 215/40/17?

Go for another drive and when decelerating push in the clutch and see does it go away.

[far123]

its a tip tronic and also when it was on the move at around like 30mph i put it in N and the noise still there no difference?

[goz_83]

is it whining, or scraping?

whining could be the tyres rubbing wheel arch liner. How is the suspension? Is it lowered? Do you have nct? Where are you based?

[far123]

Hi goz_83

its a whining noise, the suspension is lowered on apex, iam based in scotland, sorry whats an nct do you mean MOT? thanks

[mivecrx]

Could be a wheel bearing, would get louder with speed.
Gearbox bearing often whine I'm deceleration, I don't know how you check that in an auto.

Could be tyres like goz said, did it happen straight after tyres were fitted?

Any difference when car is cold or warm?

[far123]

thanks for your reply well when iam doing 30mph then i put it in N and let it come to a stop while its in N and it still make the noise, so i dont think it could be the gearbox. yeah i think i just noticed it after changing the back tyre to 245/40/17 and the front to 215/40/17. it used to be 215/40/17 at back and 205/40/17 on the front

245! what width are the wheels?

[far123]

the back wheels width are 245 and the front are 215?

[mivecrx]

the back wheels width are 245 and the front are 215?

That's the tyre width! I mean the wheels(rims). anyway I wouldn't think your wheels are that wide that you need 245s on them.

[goz_83]

check the wheel arch liners for signs of rubbing. You might have your culprit there. If it's not that, it is possible that it could be just road noise, as different tyres sound different on the road. If it's rubbing, spacers may help, depending on where it's rubbing. The best way to investigate is to take the wheels off the wheels. Let us know how you get on.

[far123]

oh ok sorry i dont know the rims i need to check that out!

[far123]

Hi goz_83

i dont think its the tyres rubbing, I put the car on jack on the front drivers side and was trying to spin the wheel and was not spinning freely? it was spinning a bit hard and stiff, is that normal because only one side was on jack?

[goz_83]

It should spin freely. So you're looking at the brake calliper, or the wheel bearing. Any garage should be able to confirm what's what, for free.

Hi goz_83

Thank you for your reply , i drove for 15 minutes today and mainly motorway then when i got home went out and touched the front disc on both side and they were very hot hot that it burns your finger when you touch the disc, and they are uprated groved and vented disc. should it be that hot to burn your finger if you touch the disc? or is my calliper piston posibily not working well?

[mivecrx]

The disc will be hot after driving, were your wheels hot?

[far123]

Hi mivecrx

Would it be soo hot that it burns your finger if you touch it? no i checked the wheels were not hot. But would a bad bearing make the wheel not spin freely?

[goz_83]

They shouldn't be scalding hot unless you were doing some heavy breaking, so it's sounding like the calliper now.

[far123]

yeah thats what i thought goz_83 , because i wasnt doing any hard braking and was driving normal so wouldnt think it should that hot after 15 minutes driving that if i touched the disc it would burn my finger and the back disc were not hot at all just the front disc.

Hi goz_83

I find out what the problem is , its a bad inner cv joint on the passenger side which is burst and got all the grease out and in very bad condition, so iam going to change the passenger side driveshaft, but i saw that there is few different kinds by any chance you know which one would fit mine and where is the best place to look for one? mine is a 4 speed tip tronic with ABS and traction control? thanks for all your help everyone
