Well, I've just spent all day cleaning my beauty. However while cleaning the wheels I noticed the brake disc holes are getting quite clogged (less than 3000miles). I did a search on here as I know this has been talked about before but could find nothing that answered my question.

Which is

What is it best to clean the holes out with? I vaguely remember someone using a drill but I could be going senile . If not what size bit?

Is there a less dangerous way?

Thanks in advance

Peter

Just prod the holes clean with anything you can lay your hands on ... like a suitable size drill bit. You don't need to actually use a drill, in fact I wouldn't recommend using a drill.

I agree, I should have been a bit more helpful.

Sorry.

Something hard and pokey should do it, the drill bit gives you more bite on the muck.

Sorry, don't know what size.

Vegatune used to do this whenever they looked at the brakes. They just got a drill-bit smaller a couple of mils than the hole (of course) and drilled slightly cross-ways in each hole to remove the crud.

I used a screwdriver on my Esprit. It's long, it's made of metal and it pokes through the hole. Job's a carrot.

I use a a proper gage penny nail with the head cut off and the point cut off . Then mount it in my favorite cordless drill. I have found drill bits to be to hard and break to easy for this job.

Thats the longer term plan but as the cars only done 3000 miles I thought I'd clean them this time

Cheers to the rest of you I'll attack them with various pointy objects tomorrow !! thumbup

How much did that cost roughly Paul? I'm thinking about it as I have never been that chuffed with the stock set-up on track.

Oh go on then








Can't honestly remember
I had the front discs and pads fitted at Brands having driven there with not much in the way of braking efficiency - well nothing at all really.
The rear discs and pads were sent in the post and I had them fitted at big sis's place.
At a guess I'd say a grand but give the guys at Plans a ring and they'll keep you right
HTH as always except in cases of abuse

One of the reasons for getting rid of the OEM drilled discs is that the discs inevitably start to crack from the around these same drilled holes. Attacking these stress points with a sharp hardened drill bit is therefore about as clever as driving right foot flat on the floor with a blindfold on, all you are going to do is promote the breakup of the discs. There's hardly any point in cleaning them anyway, they don't contribute to performance and clog up within a hundred miles or so. Leave them be and spend the time saved working to pay for the grooved disc upgrade.

If you do "have to clean them" use a pressure washer.

I've found cotton buds the best for cleaning my brakes.... the one's you use to clean all the wax out of your ears.

They fit perfect and are very cheap!!

..but only if you don't want your speedo ever to work again!
Cracking disks is certainly a possibility with drilled versions, but by no means a certainly. I ran drilled disks with Pagid RS15s on my Elise for four years and countless trackdays with not a hint of a problem. Current M400 has done 18K miles and a similar number (not the K bit) of trackdays. Again, disks are in fine fettle. If you're going to race your car with ultra hard pads, then the grooved disks are a no-brainer; for most other users drilled disks probably will be fine.
I clean mine with special tool No. SUC1245KER (otherwise known as cut-down bent coat hanger)Smooth outer surface dosn't harm disk and it's long enough to go through both disks at once.

Paul mate, are you mad, I would not suggest that at all.

As most have posted here and a regular exercise for me after track days. Take a drill bit slightly smaller than the cross drill hole. Hold the drill bit with your fingers, (not in a drill) start running the drill bit through the holes at the bottom of the disc first, that way the crud will fall out on the floor. Then gradually turn the disc round cleaning the holes at the bottom each time. You will be amazed how much brake pad powder and bits of rusty crud falls out.

Cheers,
Ian.

What about a small round file - would be easier to hold and rotate?

Dear Ian,
Point well made old bean, NEVER take a power washer near a Noble - the paint will peel off. Now of course you all know how much I worry about paintwork......
