Just got some uprated pads to go on my 04wrx now im starting to use it for the odd trackday.

The fitting instrustions say to get the discs skimmed before fitting new pads. Was looking at the discs today and they also have a little bit of a lip around the edge so they want doing.

Are there places that specialise in this or do I just need a good metal fabricators with a decent lathe to do it? Also, what is the going rate payment wise? Any recommendations in/around Lincoln?

Does anyone know minamum disk thickness allowed - think they are ok but don't want to go and get work done then find I need to buy new discs come MOT time. Discs are original, done 33k and about half way through 2nd pair of front pads, original rear pads.

The minimum thickness for your discs is 22mm , if you have more than a 1mm lip on the outside edge of the discs , they need replacing , I guess you will pay anywhere between £30 to £50 to have discs skimmed , as we charge £89 for a pair of brand new grooved discs , at your mileage I would be looking to change them rather than have them skimmed.
Hope this helps

Thanks for reply

Just been out with a torch to give them a quick measure - at the edge they are just short of 23mm but there is a bit of a lip, so im guessing once skimmed they would be about 22mm so are really ready for changing then if that is the minamum allowed.

I was told that I would have to upgrade pads on rear at same time as fronts otherwise I would be doing all my braking on the rear before the pads get upto working temperatures (which could be dangerous) Does this apply to discs too - if I go for some grooved disks, can I just do the fronts or do I need to do the rears too? The rear disks look ok - have a very tiny strip around the edge where the pads don't touch but not really a lip. Don't think they will really need changing or skimming - pad fitting instructions say as a minamum to just rough up the surface of the disk with sandpaper. Will this be ok?

Doing an evening session at cadwell next month so they can stay on til then but better get my new pads on all round and front disks on before bedford in may.

You could leave the rears as it wouldn't cause a problem. However, it would be better practice to do the pads to maintain braking distribution and avoid overloading the fronts (especially for track). Don't worry about the discs as the friction levels are largly determined by the pads, grooves are to vent gases in extreme conditions.

Break the glaze with emery paper and chamfer the edges of the pads with a file so they don't rub on the wear lip at the edges of the old discs.

Who is running the evening session at Cadwell next month as I might be tempted.

Ok, will get some front discs sorted + clean up the rears.

Any recommendations on discs?

Booked cadwell via Motersport vision - done in 20min sessions in the evening.

Blast from the past - I posted this up nearly 2 years and 2 lots of front brake discs ago!

Thanks for the links though - Im sure they will be of use to someone.
