Disk Skimmed

Any one recommend a good place to get a disk skimmed.
Front right disk is causing a judder through lever and bars.
Took it off and measured with a micrometer, lowest point is 4.21mm and hightest point is 4.29mm(measured at centre of brake rotor).
Left hand disk is with .02mm all the way round.

TIA

I took a disc to a guy in Banks which is north of Southport.
He was advertised in MCN.
Don't know if he's still there - this was about 5 years ago.

I don't think that the disks have enough meat on them to get them skimmed, but they can be straightened, with a little care, a dial gauge, and a fecking big spanner (you can also take them off, put them on a very flat hard surface, and beat the crap out of 'em).

Wellll, according the disk carrier, says min thickness 3.5mm.
So i have a bit to play with.
Straightning the disk only works if its same thickness all round and warped. Mine is varying thickness, so cant just get it pressed.

Oops - my bad! I've read so many posts on various forums about warped disks, I immediately assumed that's what you meant.
Any decent brake place should be able to do them, as long as they have one of those rigs that adequately cools the disks while they're being machined, so they don't end up warped after all.

On the VF500 I had a few years back, the right-hand caliper had stuck a bit, and that disk was badly worn. I took it to a brake place, and the techo (coincidentally a biker) would'nt machine them, as he said bikes have so little meat on them that once they're at all worn if they're machined they end up so thing that they're liable to crack, shatter, or badly warp when used in anger. I ended up buying some secondhand NS or NSR250 disks which were identical in size, but drilled rather than plain. Worked a treat.

Good luck - hope you find a suitable brake place.

I was recommended not to have discs skimmed when i had a wobble, cos they're not meaty enough to take it long term.....

I bit the bullet in the end & bought a set of waveys...(much cheaper than replacement Hondas)

Hi Essexbloke
How would you rate the wavey discs in comparision with the standard discs, I know they look good!!
cheers Chris.

in my personal experience, they're much better. Have better stopping power (better bite), although they are reported to wear the pads much quicker due to rough sharp edges.

It's also reported that they disperse heat better, negating warping.

Apparently they're better for good stoppies too, (my cahoonas aint big enough for that though)

I'd reccommend them over standard any day, and as i said, they're universally cheaper than standard too.......it's the way forward....

oh and yep, they look nicer too.....

Essexblokes brakes are real good, I can testify to this as I test rode his bike after doing some work on it (he was abroad) and found them really good compared to standard. His bike also wheelies quiet well too, don't tell him, ssshhhhh.

Well, ordered me a rebuild kit for the disk.
Â£65 from Trade direct who do the Viper Stealth disks.
Once that's done, she'll be up for sale
