Hi

I would be very grateful for a bit of advice about whether I need to replace my front brake discs

Graham O'Conner of Lambda Motors, Mittagong, NSW converted the brakes themselves to Girling callipers, but the hubs/disc set up looks like 1st series to me (see attached photo).

I have a vibration on my front right wheel on braking from speed and the disc seems to be warped since turning the hub through the calliper by hand gets a bit hard to move in one particular place. The right hand disc measures 10.85mm (and the left 10.55mm).

So my question is can I skim the right hand disc to sort the warp, or are both discs getting a bit thin?

To replace the discs I am aware that I need two hub tools (outer and inner) and will need to buy new outer lock rings. Can I borrow/hire these tools from the LMC? The wheel bearings have been changed in the not too distant past so I am expecting the hub nuts to come off relatively 'easily' (famous last words).

many thanks
Simon

The Fanalone (1.6HF) had light weight disks down to 9.0+/- 0.11mm so you can possibly do a light skim.

Yes the club has tools to undo the hub. It is on v tight unless not done up properly at the last time of dismantling. c 200ftlb so I doubt your vice will be able to hold it . From my experience at least a 4ft scaffold pole is required to get the controlled leverage. The tool itself needs to be held tight to the hub as it will spin off and wreck the tool. I believe it is provided with its own steady system the screws into the end of the drive shaft..... S1 hubs have a dowel system that needs removal before undoing the main nut.

I am the tools guy for the club so you can PM me or email me below with your requirements. Tools are hired out for an initial fortnight with a substantial deposit which is returned on receipt of the tool back to the club.

Hi Tim

Very useful and comprehensive answer. Many thanks.

I'm going to see if I can get a pair of thicker secondhand discs first I think. Given your 'possibly' it would seem a sensible thing to do before I start getting the hubs/discs off. The car has been off the road for two years following a engine failure (broken valve mashing the head) and a partial rebuild/restoration, and the current discs certainly don't detract greatly from the enjoyment of the car, and I am very near having it on the road again.

I will get in touch again when I have the discs and a length of scaffolding!

Many thanks
Simon

Simon,
Have you thought about getting the discs skimmed on the car? mine were done many years ago, but I believe you can still get it done, this would save all the hassle of changing the discs, you may also find it a problem to get hold of any secondhand ones, for years new ones were unavailable,  but Cavelitto can now supply, I bought one when we were in Turin 2013 to match one I'd had for years.
I now have a complete set of front and rears.
I know you say the one is catching in the caliper but that's not unusual if you've got a bit of dust on the pistons, or even a bit of rust or pitting on the disc itself.

Fulvia disks are very hard and dont wear much. As Brian says it could just be a wear mark. It could be a loose / worn bearing?? When I first had my HF a previos owner had not done the hub bearing up correctly so it wore away the inner stub ( part with the splines that connects the drive shaft and hub ) causing the hub to fall out of alignment. I will measure my second hand spare disks as I think you could easily take a skim.

Ah, so discs can be skimmed without removing them from the hub? If that's the case then thats the obvious first job to do

Thanks

Just measured some new disks on my S1 and they are 11.25mm. Some very secondhand ones measure 11.15mm

Hi Simon,
I've just Googled 'skim discs on car' and it immediately came up with a number of hits, the top one being for ' tecalamit' equipment. With the facility to enter a postcode or location which then will show a map with one near you.
I put in Cambridge and it came up with the Porsche Dealers in Haslingfield, however it does state that some only do it for their franchises such as Porsche and Ferrari, and please don't contact them unless you have there models, however I would have thought it's worth talking to them.
Seems it takes 9 minutes per disc , the video of the job being done is worthing viewing.

I know Autoshield (0161 881 346) Manchester used to do this for Maserati brake discs before we sourced the discs from a non-Maserati supplier (at 1/3 the cost of OEMS). Ask for Marios and see what he suggests, perhaps a bit far away from you.

No it is generally only able to be done on fronts where there are no back plates and grinding is don on the exposed part of the disk as it rotates by the machine...

many thanks for all the responses. Found this guy here - Marcus - and spoke to him - http://www.discskimmers.com/7.html.

He also said that if it wasn't the disc causing the wobble, his machine would be able to tell me. So if there is a hub issue I'll know

Many thanks again. I now have a course of action which doesn't start with hub removal, which is a good starting point, me thinks

Thanks also for the offers of second hand discs. Which if this process doesn't sort I will be in touch about.

Should have the car on the road in a few weeks. Battery on order

I should add that the driveshaft stops the hub from wobbling about which I suspect you do not want when trying to skim the disk.

I wonder about the hub carriers, as normally one can't fir Girling calipers on 1st series hubs.  I was told the rotating joint (don't know the correct english word) tapers for 1st and second series cars have different angles, and swapping hub carriers between series is not possible?  At least something to check, as there might be a dangerous combination.
