Are A/C and brakes linked?

[bendybead100]

Hi, for the last few weeks every time I break there is a squeeling/crunching noise when I brake.  The brakes were done 7 months ago. I noticed today that I've been driving for the last few weeks with the a/c on so I turned it off and now the brakes are making very little noise. Is there any way that the a/c was causing it?

Thank you.

If it were the brakes then it could be a stone caught up in the disc or even the backing plate rubbing against the disc.

If it is the air conditioning system then it could be the gas cavitating or the drive pulley or belt.

Either way, I would take into a garage to have it diagnosed as this could lead to more expensive repairs if not attended to soon

Let us know what you find

Thank you Trevor. Will do.

Hi , any update on this?

Did you get it sorted?

I did. Trevor was right. One of the calipers had split and was rubbing on the disc.
