dirty brake discs

all brake pads, new and old, make brake dust.

the rust colour isnt a major problem!

brillo??? lol

i dont know to be honest but it isnt a problem apart from aesthetically as mine do it (on every car i have). it doesnt affect the braking.

To stop this simply spray the brake discs with WD40 or similar lubricant. PM me for details before doing the procedure.

genius, what you can see is RUST due to the fact that brake discs are made from a ferrous metal i.e. cast steel. All makes of car suffer with this phenomenon, some worse than others.

Always dry out the brakes after washing the car by driving around the block and applying the brakes to heat them up. This will minimise the corrosion.

Brake discs almost always corrode more on the inner surface than on the outer one. I have never heard a satisfactory explanation for this but I have my own theories.

stuart, I wouldn't want to use WD40 on my brakes; they work better without lubrication!

Is my humor too dry?

NO, too oily!!! Ha! Ha!

Miosture in the air. Another way is if you washed it before parking it, the rust stains wouldn't show up for days.

Some metals are "Self Protecting" Cast Iron and Aluminum (no matter how you pronounce it) are two that do. They rapidly develop an oxide layer that seals off the surface from further corrosion.

Aluminum gets a hazy dull layer of aluminum oxide and cast iron gets a thin layer of iron oxide, commonly known as Rust.

Every time you use the brakes you wipe the rust off and every time you park it the rust starts coating it again. Normal!!
