Cleaning new brake discs?

[scotsgent]

Hi,

 

I have just taken delivery of a set of Ferodo rear brake discs for my Octavia 1.

 

The diagrammatical instructions (pictures not words) seem to indicate that they should NOT be cleaned before fitting.

 

Usually, I have removed the protective rust-proof coating which is applied at the factory with alcohol or somesuch.?

 

So, which is right?  Remove the stuff or leave it on?

 

Cheers,  Terry

I remove with Brake Cleaner. 

I Clean off of new cars discs as well before 'Driving In' as Skoda call Running in.

Often new discs are coated with a special paint (ATE does that) and that doesnt have to be removed. Just carefully brake it off.

Will give some strange noises at first, but that is normal.

 

On my picture you can see the new discs, still with the coating.

Indeed  'magic', it seems you are right!  :clap:

 

It seems that Ferodo's range of 'Coat+' discs have a painted coating and not the usual thin, removable, oily protectant.

Here's the important bit: 

 

"15th September, Bradford, UK… Federal-Mogul Motorparts, a division of Federal-Mogul Holdings Corporation (NASDAQ: FDML), has seen a positive response from automotive aftermarket customers for its COAT+ coated brake discs.

 

Originally introduced in 2011 for a selected range of high-end vehicles, the company now plans to roll out the advanced protective technology to 95% of vehicle applications. "As more cars are being fitted with alloy wheels that feature an open rim design, brake discs are becoming clearly visible," says Jonathan Allen, Regional Marketing Manager, Federal-Mogul Motorparts. "This is increasing the desire for braking systems to be aesthetically pleasing as well as be able to deliver excellent braking performance.

 

We believe this is one of the reasons behind the growing preference for Ferodo COAT+ coated brake discs. The practical benefits of ease of handling and time saved for the installer by removing the need for degreasing prior to fitment is also driving demand." Ferodo COAT+ brake discs, which provide customers with the assurances of a top performance brake disc with the added benefit of unblemished looks, are finished with a zinc and aluminum flake spray that is evenly coated onto the full surface of the disc. This thin and very consistent covering, which is just 6um (micrometers) thick, not only improves the appearance of the disc but also removes the potential for disc thickness variation, which may be apparent with lower quality coatings and can lead to judder and brake noise.

 

Ferodo COAT+ brake discs also offer corrosion prevention qualities and are resistant to automotive fluids such as brake fluid, greases and other strong solvents which can be present during the installation process"
