Roger Ford Posted February 3, 2009 Share Posted February 3, 2009 Had one of my rear discs off today and noticed that it has a pronounced ridge round the outside. Measuring it up shows the ridge is near enough 10mm across, and the main disk is about 8.7mm. So it's worn by a little over 1mm. Should I replace it (and the other rear)? I'm inclined to, because they're cheap - £22 each. But on the other hand the surfaces are smooth and clean apart from the ridge, and it is £44 that might be spent on something else. Standard Triumph Herald discs with Sierra calipers, Pagid RS14 pads, use almost exclusively track/racing. Link to comment Share on other sites More sharing options...
CharlesElliott Posted February 3, 2009 Share Posted February 3, 2009 The wear limit is engraved on the circumference of the disc. Charles --- Triple E Racing - build diary and race reports Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted February 3, 2009 Share Posted February 3, 2009 If you can unearth it under the inevitable corrosion around the outside ! edit: wouldn't be too concerned about 1mm of wear. Problem arises if new pads (when replaced) are slightly larger - then you have to grind the lip off, or change the discs.

Englishmaninwales Posted February 3, 2009 Share Posted February 3, 2009 Much cheaper at Rimmer Bros £14.38+vat here Malcolm Edited by - Englishmaninwales on 3 Feb 2009 10:24:51 Edited by - Englishmaninwales on 3 Feb 2009 10:28:12 Link to comment Share on other sites More sharing options...
Roger Ford Posted February 3, 2009 Author Share Posted February 3, 2009 £14.38 including VAT by the look of it. But their web site doesn't tell you how much shipping will be. Quite a lot, I imagine, whereas CC are still doing free delivery. Have emailed for a quote. I might worry that the discs aren't identical to the Caterham ones and therefore not race legal, but given that I've had three different types from Caterham in the past, I don't think this is really an issue.

Stationary M25 Traveller Posted February 3, 2009 Share Posted February 3, 2009 Aren't CC only free delivery on orders over £50 ?? Link to comment Share on other sites More sharing options...
Roger Ford Posted February 3, 2009 Author Share Posted February 3, 2009 No - CC seems to be free on anything ordered from the web site. Update: Dammit, the free shipping has gone. It was there last night! Now it's £14 for two discs Rimmer Brothers said postage was £48.00 *eek* When queried, they said the only Roger Ford they had on their database was in the US, and that UK postage would be £9.95+VAT. So that makes RB £25+£9.95+VAT = £40.19, and CC (was) 44.86 (now) £58.86 Link to comment Share on other sites More sharing options...
mav Posted February 3, 2009 Share Posted February 3, 2009 Call CC and ask them to price match. Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted February 3, 2009 Share Posted February 3, 2009 As you know they are Herald discs, why not try your local motor factors, or high street shop ? Or .... I could pick them up from CC for you. Do you know anyone that lives near Caterham on the Hill - I visit there every Saturday if that helps ?

Allen Payne Posted February 3, 2009 Share Posted February 3, 2009 There about £10 +vat from Moss Europe which is not far from you here Edited by - Allen Payne on 3 Feb 2009 11:42:42 Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted February 3, 2009 Share Posted February 3, 2009 I like the .... Brake disc, or Brake Disc High Quality. What does that say about the £10 one ? Link to comment Share on other sites More sharing options...
Roger Ford Posted February 3, 2009 Author Share Posted February 3, 2009 Interesting. I too wonder about the "high quality" version! I occurs to me that while I have the driveshaft off (which I have) I ought to replace the wheel bearings. Caterhams part cost £21 here - is that for one side or both? Anyone know the code for this so I can try my local bearing factor? Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted February 3, 2009 Share Posted February 3, 2009 Definitely each !! If you get a part number, let me know, as I want to ask my bearing supplier pal about the rears. He is normally very competitive. Edited by - Stationary M25 Traveller on 3 Feb 2009 12:37:09 Link to comment Share on other sites More sharing options...
Roger Ford Posted February 3, 2009 Author Share Posted February 3, 2009 I'm taking my driveshaft to James Whiting this afternoon to get the gaiter replaced, I'll see if he sells the discs (to save mail order) and ask about wheel bearings there too.

Roger Ford Posted February 3, 2009 Author Share Posted February 3, 2009 SM25T - thanks for the offer, but passing them around various people seems like a lot of effort! I did try my local motor factor but they wanted £35 each. And high street car shops? None of them left round here (we had three when we moved in), do they still exist?

Mick Day Posted February 3, 2009 Share Posted February 3, 2009 From my notes the discs are 10.3mm thick when new & the wear limit is 8.3mm. I would think James would have the discs & bearings in stock. I think the rear bearings need to be fitted using a press. Link to comment Share on other sites More sharing options...
CharlesElliott Posted February 3, 2009 Share Posted February 3, 2009 As said, rear bearings need a press. Repalacing the gaiter is easy, even you could do it Roger. 😬 Charles --- Triple E Racing - build diary and race reports Edited by - CharlesElliott on 3 Feb 2009 14:36:39 Link to comment Share on other sites More sharing options...
Roger Ford Posted February 3, 2009 Author Share Posted February 3, 2009 Really? I read in various places that it was a real swine of a job. Anyway, bearing carrier and driveshaft dropped off with James Whiting today, and CC discs ordered through him (CC price, no postage). Issue I have now is that since I have to take the other hub off to swap the other disk, I really may as well get the bearings done on that side too. Which means an extra trip to JW. I really should plan these things better! Link to comment Share on other sites More sharing options...

Roger Ford Posted February 3, 2009 Author Share Posted February 3, 2009 Duh. Oh well, at least the bearings will get replaced. Link to comment Share on other sites More sharing options...
Englishmaninwales Posted February 3, 2009 Share Posted February 3, 2009 Rear bearings can easily be removed with a drift and hammer rather than resorting to a press. The new bearings can be similarily be drifted in, initially use the outer rim of the old bearing, then finish with a soft brass drift. The grease seals can carefully be tapped in. Be careful not to tap the seals in too far. I made the mistake of replacing 50k mile original bearings for no good reason other than the mileage, only to be supplied with faulty bearings (apparently a faulty batch)that failed within 8 k miles that destroyed the bearing carrier and damaged the driveshaft......if they are working ok and no evidence of wear I'd leave them alone. Edited to add... Roger the bearing failure was catastrophic, and I was luck not to have ended up in the hedge Malcolm Edited by - Englishmaninwales on 3 Feb 2009 23:51:44 Link to comment Share on other sites More sharing options...
