had my supra discs skimmed today, had enough of pedal jumping and wheel wobble under braking.

started like this




marcus at disc skimmers came out with his pro cut lathe and finished up with this





havnt tried it yet but looking good, the main issue he said was the fronts, cheap spacers had been used and they wernt square so the wheel and disc bell wernt faced together square, so ive ordered some h and r cnc machined spacers for a dead true fit.

seemed very professional and discs look like brand new now, i will report how much better they are as soon as ive driven it.

 

We have 2 procut machines at work. Used to use them all the time for warranty skims - nice bit of kit. They just sit in the store room now gathering dust.

 

How much did it cost, I've seen prices before and they where the guts of a new set of discs.

 

£180 for skimming all 4 discs and £27 mileage.

he came to me and done it on my ramp.

i dont know how much my discs are new but i have the receipt for the brakes brand new 2009 £4960 ! so very worthwhile for me to try it.

 

Not bad although If it was for one piece discs you would probably be better off with new discs

 

I used to do that all the time on toyotas.The skimmer sometimes takes a bit of setting up to get it to sit.right on the hubs.

 

Before they became tight arsed with warranty claims? Haha.

 

How do they do the back's then?

 

Worth it on the 2pc set up. But not on a regular disc. I have had my mate skim them in a lathe before for me and that was ok as it was a favour like.

 

Back face of the discs? The machine has 2 cutters, one does front face and other does rear, both at the same time.

used to do this all the time when i worked at a mitusbiti dealer

 

Discs and pads on Toyotas were shite.I did a Toyota eygo that had 1500 miles on it and the discs were badly corroded.

 

They still are shite. They won't auth as much warranty as they used to do.

 

Had discs skimmed on my mondingo a few years back as a wheel bearing replacement left the hub not quite square and the disc kept warping

Was a cheap effective solution the on car skim.

 

I just left toyota when they started to change the engines under warranty for poor oil consuption.

 

well the h and r spacers finally arrived so i got the car off the ramp last night and took it for a blast. all ive done is had disks skimmed, cleaned and greased all pads so the move freely and fitted new clutch hub carrier ring and had flywheel skimmed and my wot fueling has gone from 11.4 to 10.6 afr !
i could feel it aswell, hits 10.3 as i come on boost now which is so rich i could feel it starting to misfire ! so the engine must be under less load now so needing less fuel, so ive droped the fuel pressure off slightly so im back at 11.4 again.
the brakes fel 100% perfect now, 100 mph hard on the brakes no judder or squirming just pulls up in a dead straight line.
my base fuel pressure is running nearly 4 bar, god knows why it was mapped like that its ridiculous im hitting 6 bar rail pressure at 2 bar boost !
so i think i may get mgt to map it soon at 3 bar base pressure at least it will give the pumps an easier time.
