panhard65 Posted June 25, 2016 Posted June 25, 2016 The garage I used to work in had one of those disc re-facing machines. I think it only came out of the box once when I used it to do the rear discs on my Jensen 541. It was such a faff to set it up that new discs were always the cheaper option if they were available.
cort16 Posted June 25, 2016 Posted June 25, 2016 It does look like a faff. I just thought it was odd it's quite common in the states where they;re so keen on just chucking stuff away if it's even 1/2 done in.
cort16 Posted June 25, 2016 Posted June 25, 2016 In other news my Randy Panda 100Hp is done. The running total is getting pretty close to what I would have paid to buy a decent one in the first place but ho-hum. It still needs the door fixed but I might nip up to the scrappies and see if they have one in black I can swap over.

I'd be interested to see how they true them up to the (obviously not fixed)lathe on the car.

I'd be interested to see how they true them up to the (obviously not fixed)lathe on the car.It was a long time ago that I used it but it bolted on in place of the caliper and you set the grind stone against the disc then rotate the disc. I only used it to clean the discs as the car had been sat for 30 years. I really didn't trust it to do a decent job and only took the minimum off, it did however work with no noticeable judder afterwards.
loserone Posted June 25, 2016 Posted June 25, 2016 A few months ago my father took his Auris to a local (chain) garage as the Toyota dealer had insisted he needed to spend a grand on discs all round, as they had a 'lip' on the outside. Local garage declared the discs fine, and offered to take the lip off. When I next saw the discs, the lips had been pretty carelessly taken off with an angle grinder, and they were scored randomly across the entire face. A re-facing machine or a lathe seems like a much better idea..
spike60 Posted June 25, 2016 Posted June 25, 2016 While the marks from the grinder don't sound very professional if it brakes ok they won't matter. The cast disc is soft and will soon wear away the marks, discs are pretty much disposable these days. I reckon skimming and grinding dates dack to old hard discs which were probably meant for asbestos type pads. crapcarcollector and Lacquer Peel 2
cort16 Posted June 25, 2016 Posted June 25, 2016 I've taken the lips of discs with a grinder before and it worked fine. That edge is the bit the pad never really gets to so if you're careful you can do it without really grinding the contact area. I think the proper re-facing lathe tools will fix warped discs, which seems to be the reason I always end up changing them.
spike60 Posted June 25, 2016 Posted June 25, 2016 Unless it's catching the wear sensor or wire the lip doesn't matter as far as I know but it is a handy guide to how much disc has worn away! Most car discs I change are worn thin or corroded, the only times I've had warped ones is the only times I bought Mintex. I change quite a lot of discs at work on commercials, they start 45mm thick, 1 or 2 pad sets take them to the 37mm must change thickness.
xtriple Posted June 25, 2016 Posted June 25, 2016 There are quite a few of these 'on car skimmers' around. I was recommended a chap in London who I did ring but he didn't fancy a trip to Torquay! He suggested a few down here and Pollits of Exeter are doing it. Looking on the website, there are LOADS of garages with the machine locally. It's got to be better than 2 or 3 grand on new discs? Fucking ridiculous prices for discs. I should learn to live with faults - I'd be both happier and better off!
cort16 Posted June 25, 2016 Posted June 25, 2016 I mean how they do they justify 3 grand for discs, it just doesn't compute? It's not like they're carbon ceramic or anything

It's not like they're carbon ceramic or anythingThat's with the two day (for the rears) labour. £400 for each front disc, £300 (ish I think, not looked for a while) for the rears, 6 hours labour to change the fronts, two days to do the rears. So,£1400 for discs.£1760 labour£632VAT£3792. All in.... FUCKING OUCH!
dave21478 Posted June 25, 2016 Posted June 25, 2016 Inboard or not it shouldnt be taking TWO DAYS to change a pair of discs...I dont care how complicated the rear suspension is, thats taking the piss. andrew e, xtriple, Lacquer Peel and 2 others 5
cort16 Posted June 25, 2016 Posted June 25, 2016 just do what classic bodgers of old did on jags and cut s hole in the boot floor then weld it up once the discs had been changed Eddie Honda and andrew e 2

twosmoke300 Posted June 25, 2016 Posted June 25, 2016 Even jag irs ones don't take 2 days - complete piss taking there I'm afraid scaryoldcortina and xtriple 2
xtriple Posted June 25, 2016 Posted June 25, 2016 Yes, I've had a butchers now as well and they do look easy(ish) certainly easier than old inboard Jaguar ones. Also, can't see why the fronts are 6hours to do either, they look like a million other cars which are an hour per side. Perhaps there is a special 'speed' that is needed to be used on Rolls Royce products when working on them? You know, like that one just between 'dead slow' and 'full stop'. I do sometimes fear that my beloveds up at Specialist cars take the wee-wee a bit on times, but then, no other fucker will work on this car so what am I to do? The next nearest specialist is Bournemouth and with my luck and this car, it'd need repairing at both ends of the journey!
xtriple Posted June 25, 2016 Posted June 25, 2016 Yes, it does look a tad tricky with splined shafts and stuff but still... Lacquer Peel 1

dave21478 Posted June 25, 2016 Posted June 25, 2016 Its all just nuts and bolts......That exploded diagram doesnt look particularly complicated, I would say no harder than the front hub of a Frontera or similar 4x4 with an auto locking hub. I guess the two days thing is to justify having a shiny workshop thats cleaner than most restaurant kitchens, with a Bently logo emblazoned on the floor, surgically clean tools each set in a blue felt-lined cutout in an individual drawer in a tool chest, a white overall wearing apprentice who retrieves the tool, who passes it to the second-mechanic who wipes it on a clean bit of cotton before handing it to the chief mechanic who unscrews the nut then hands it back to the second-mechanic who wipes it on a different bit of cloth, hands it back to the apprentice who slots it back into its storage place while Mozart plays from a 30k Bang and Olufsen stereo in the corner. Then they have to stop for a while because its Pimms O'clock. At least, thats what I imagine a Bently garage should be like. I think I might be disappointed with the reality. egg, Brodders, rml2345 and 7 others 10

I think I might be disappointed with the reality.I fear you would be VERY disappointed! Though I must admit, it is the cleanest, tidiest workshop I have ever been in, not posh but very ordered, quiet and well laid out. Other thing is: I really like them all up there (even though my inherent distrust of garages/mechanics/car sales places initially left me open to cynicism) and they do know their stuff, knowledge like that is worth fortunes and takes a long time to gain. When all else fails, they ask the 'old man' who has done and seen, it all, usually several times over. Also, they have to pay for the holidays in Barbados somehow
Guest Hooli Posted June 25, 2016 Posted June 25, 2016 Yes, it does look a tad tricky with splined shafts and stuff but still... Looks no more difficult than my old Discovery. The only way that'd take two days is because it's all rusted together & snaps when you start to undo it. Lacquer Peel 1
vulgalour Posted June 25, 2016 Posted June 25, 2016 Full of hope I headed to the unit to see about getting the Renault fired up and having set the points gap and sorting the ignition timing (I hope, anyway) I decided to see if there was a spark before attempting to fire up off a remote fuel supply. There is no spark. The rotor arm, distributor cap and spark plugs are all new but the coil, condenser and leads are all old so I guess I need to spend more money to make any further progress. It is also too hot in the unit to even move, so rather than lose my temper I just went home again. purplebargeken 1
cort16 Posted June 25, 2016 Posted June 25, 2016 I bought an impact driver for the decking I'm attempting to build out the back of the house. It's flippin brilliant, it whacks huge screws in 2 seconds, which is great as my old 12v electric screw driver/drill was hopeless. The Moog 1
Ghosty Posted June 25, 2016 Posted June 25, 2016 I was right The old shocks were so badly fucked they were easily compressible by hand (!) and didn't rebound, so there was literally no rear suspension. Rear ride hight is something like +25mm on before. It doesn't look as good now admittedly (at the back at least), but it's levelled the front out a bit and I won't be as averse to travelling places in the rear now. Hopefully it's stopped that bloody banging noise too. andrew e, purplebargeken, anonymous user and 1 other 4

Guest Hooli Posted June 25, 2016 Posted June 25, 2016 As reported on the Franken-goona thread, normality has been restored. FTP on friday morning, obviously on strike over the voting. WD40 in the UCH & sealant around the sunroof should have fixed it again. Urko 1
omegod Posted June 25, 2016 Posted June 25, 2016 Impact wrench is for loosening nuts, impact driver is for screwing stuff in, both bloody excellent !!
