Cleaning out holes in 996 brake discs

[villageidiot]

Rather than me buying a set of drill bits, can anyone tell me the correct size drill bit I would require to clean the holes in my brake discs on a 996 C4S (2004)
Thanks

Lol spent two nights this week doing this! 4mm will do the job to clear brake dust etc Disc would take a 5 mm hole but requires patience and more work.
Get more than 1 bit as you may break them if you go cheap.

If you have access to a power air hose, it takes less time and less chance of marking the discs.

Use a kebab skewer, a long wooden one.
This works best.

This is what I did. Certainly didn't take two nights with a drill bit; more like a few minutes.

I thought I was quite obsessive currently about cleaning the car, but this is a new one on me.

I will be going home and inspecting the holes!

If you are going to do that, Make sure you give the car a good blat on the way home to get the brakes nice and hot, otherwise they will corrode in no time.

Does the job perfect and washes all the crud away rather than have it gather at the bottom. Just give the car a spin round the block after to get rid of any water. This is probably the easiest method of doing it without ruining your back or taking hours with stupid fiddly drill bits. Obviously dont point the jetwash into the calliper if it a powerful one.

The view is that heat does not dissipate so quickly if the holes are blocked, obviously presenting the possibility of the discs degrading prematurely. No harm in doing it, except the OPCs use it as an income generator.

Eh?? How do you normally wash your car or drive in the rain without getting the brake discs wet then?? Lol.

Fit PF fully floating discs, then you won't have to do all that stuff as they are dimpled rather than drilled

[bobsan]

forget your drill bits, these scent sticks are just perfect for the job and much quicker, plus she will never notice a few missing.

yeah yeah ocd kicking in again.

Although, as for drying after cleaning.
Depends when it is next going to be used.

If the car isn't going to be driven for a few days ill take it for a quick spin after washing.

Steel rusts. Why speed up the process.
