I've noticed the brake calipers on my 156 are a sickly brown color. Like they are corroded in rust. And one of them has startd to turn white !!Have checked out other 156's and they are not as bad. I wonder could this be the reason I end up with so much brake dust.
The dealer says he has something that will clean this up. So bringing my car in on Sat. Can anyone tell me if this is normal. Should I be worried ?
The other thing I've noticed is that there is a lot of rust on the discs, and on the sides of the wheel hubs. I know getting rust on the discs is normal, and it comes off when you brake a few times. But is it normal to have it on the sides of the hubs which are behind the discs. I had this problem on my 147 also, and the dealer explained it is due to the fact that the hubs are made from cast iron and will rust in this manner.
Actually I feel a bit silly for posting this question.
I used autoglym clean wheels. Washed each wheel first. Then sprayed the cleanwheels onto the brake calipers. Worked it in with a soft brush. Afer maybe 20-30 seconds all the grime and dirt came off. Hosed the wheel off, and the brake calipers look like new now. Plus I'm getting very little brake dust.
Should have known this, as I detail cars a lot. Was just a bit shocked that my calipers were so bad after 2-3 months.
