Re: Mtec brakes corrosion after paying extra for protective coat

The metal in rake discs take a lot of battering. Imagine one minute being really hot and the next being doused in freezing cold salty water. Additionally the size of the surface area can affect the rate of corrosion or temperature variance. Don't forget drilled or grooved discs have less friction area but also a higher rate of heat disapation.

Also the design of the disc can help. You really can't always compare how a disc of one make of car compares with another as on some cars there is an undercut between the centre hub and the disc surface - this reduces the risk of corrosion creep.
