Drilled holes in discs full of brake dust

[MikeyMaser]

Hi

I took my GTS to a main dealer for an end of warranty health check. Everything went fine and the car is in good health! Crazy as it may sound, I've decided to run the car without a warranty as I've had no issues at all in my first year of ownership.

One thing they noted was the drilled holes in the discs were full of brake dust. They said this could impact braking performance, cause the brakes to overheat and/or the discs to warp. Ha ha, yeah, if I was running in it the Le Mans 24 Hour race!

Anyhow, just wondered if anyone knew a DIY method of getting rid of the brake dust or a company that could do it? The main dealer wanted £300 to do it which I, of course, politely declined.

Cheers
Mike

I paid £150 at my last service for this - was at a MD Maranello in Egham. The alternative is to DIY I think by drilling each whole... But it needs to be done really.

Battery powered drill with a masonry bit works very well. Masonry bit because it has a harder tip and clears the hard compacted debris more easily. Time consuming, but very satisfying.

Do this on my 911 every now and again and Porsche charge a similar cost but I refuse to pay. Takes time but I used a normal drill bit held within a chuck and turned by hand. It is well worth doing not for braking performance but for preventing disk corrosion internally in the disk (that you can't see until it is too late). Also it takes a couple of years (depending on usage) before it needs doing again.

Now guess what, I need to look at the GT when I get home to see if it needs doing as I haven't checked for a while. Doh!

Thanks for the replies chaps, I shall try and find a garage locally who can do it for a more competitive price!

It literally is as easy as removing 1 wheel at a time and sitting with a battery drill to do it yourself.
No need to do all 4 at once but I would do in pairs!
So maybe take you 2 mornings / evenings at most!!

Um
I *think* some discs have the holes offset so you need to take the disc off.

Can not see why you need to take the disk off just turn the disk to access all areas. I did this on my 4200 before the group buy disks turned up. I did use a hover as well to takaway the dust.

Because the inboard disc (assuming that it's vented) has holes which do not line up with the outboard disc. Ergo you cannot put your drill all the way through. Or at least it would be 'inadvisable'

I *think* this is the case with *some* discs which *may* be fitted to our cars.

Or I could be wrong.

The rears on mine go all the way through, but the fronts don't. Easy enough to do all of them in situ.

A local spanner monkey I trust says he'll do it for £60. Just a matter of getting the car up on a ramp, taking each wheel off and drilling through the holes. Reckon it'll take him about an hour.

 

[philw696]

Yeah that's what we do here 15 mins a corner.

 

[Felonious Crud]

DIY job, and a satisfying one at that. You'll be amazed at the amount of filth which you drill out. Takes me a bit longer than Phil's 15 minutes per corner but I'm an amateur.

Incidentally, the holes on mine are aligned so the drill bit goes straight through.

I don't do manual labour! So, I'll leave it to my spanner monkey...

I've just come back from my local tyre shop and had all 4 wheels taken off and the discs blasted with compressed air in each hole. All nice and cleaned up now - cost £20 plus £5 tip for the lad who did the job. There was crazy amounts of brake dust flying around and the nutter was using his T shirt to mask his mouth and nose.
After a stern telling off he got himself a face mask :-o

 

[philw696]

I can't believe compressed air did a proper job as they can take effort with a good drill bit as there is rust as well.
That crazy fool won't make it to my age and you will all have breathed some in.

[hodroyd]

Normally a drill bit will do the job, you don't have to have it in a drill, just use the bit itself..!!

I like the opportunity to wash wheels inside and out when I do mine. If the sun is shining I apply wax too, which makes brake dust easier to hose off.

FYI. If you can drill right through both disk surfaces, likely you have Ferrari disks fitted (my 3200 has 550 disks)

If you still have Maserati disks, access the inner faces of front disk by applying full steering lock. Rears just needs a bit of a reach around.

I was standing well away from where he was working....The holes are completely clear now as I manged to push a pin through many of the holes and see it the other side...

You should be able push rather more than a pin through! I think they are about 5-6mm
