caterhamnut Posted August 16, 2006 Share Posted August 16, 2006 IF I wanted to get some Pagid front brake pads (which ones RS14 or 15?) for our car, what would be the part number/type if I am running with Alcon brakes? cheers www.mycaterham.com here Videos here 96,000 miles -1st 1.6k Supersport, '95 Motor Show car Link to comment Share on other sites More sharing options...
Mick Day Posted August 16, 2006 Share Posted August 16, 2006 James Whiting recommended RS15 front, RS14 rear. Performance Braking Ltd, 01600 713117 is another good source of advice. Edited by - Mick Day on 16 Aug 2006 09:58:03 Link to comment Share on other sites More sharing options...
caterhamnut Posted August 16, 2006 Author Share Posted August 16, 2006 Cheers Mick - but do you know what the part number is to get the right shape/size pad? www.mycaterham.com here Videos here 96,000 miles -1st 1.6k Supersport, '95 Motor Show car Link to comment Share on other sites More sharing options...
Jason Plato Posted August 16, 2006 Share Posted August 16, 2006 what John @ PB usually sys is forward an outline of the pad backing material and he will either size one up or make a backing to suit I thought James Whitting always promoted Greenstuff ? or has he upgraded 😬 Link to comment Share on other sites More sharing options...
DohNut Posted August 16, 2006 Share Posted August 16, 2006 I would have thought if you asked for a pad for a particular caliper it puts the emphasis on them to give you the right pad. Just speaking as someone who incorrectly filled out a code number recently. 🙆🏻 FWIW they may/should know the caliper as Alcon sell it to anyone with the mounting lugs unmachined. James simply gets a batch machined correctly. N PS good news about them being able to change the backing plate , I have been looking at the Willwood calipers but not exited at the thought of having to use willwoods (own brand) pads.

Jason Plato Posted August 16, 2006 Share Posted August 16, 2006 its just trying to help folk Dohnut and to ensure that the part is correct. Sounds like an agressive stance to take for something as simple as ensuring the back plate is OK . Link to comment Share on other sites More sharing options...

DohNut Posted August 16, 2006 Share Posted August 16, 2006 Aggessive 🤔 I was simply suggesting that somtimes trying to get a code number can be counter productive as they can be easily misread and are liable to change for many reasons If you simply ask for a product in plain language there is often less scope for misunderstanding. Infact when I used PB to buy my pads last month there was a mix-up with the pads being quoted for but because the conversation was in plain english the confusion was easily picked up, where I may not have noticed on digit difference in a code number, and got the right pads - every one happy Nick Link to comment Share on other sites More sharing options...

Nifty Posted August 16, 2006 Share Posted August 16, 2006 James Whiting used to support Greenstuff until they changed their material .. he now goes for Pagid RS15s .. or so went our conversation the other week Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
Myles Posted August 16, 2006 Share Posted August 16, 2006 John Freeth (Frith???) at Monmouth Performance Braking also recommends 15s on the front by the way - he frequently gets a mention when Pagids are the subject of conversation. They are fecking noisy (in many ways) in my HiSpec Ultralite 4's, but I think that's mainly down to the clappers. Project Scope-Creep is live...

caterhamnut Posted August 17, 2006 Author Share Posted August 17, 2006 If my discs are almost new (ie: no grooves or ridges at the edge) can I get away with just cleaning them with emery paper rather than replacing, which I know is sometimes recommended with pagids? www.mycaterham.com here Videos here 96,000 miles -1st 1.6k Supersport, '95 Motor Show car Link to comment Share on other sites More sharing options...
Archie Procter Posted August 17, 2006 Share Posted August 17, 2006 Angus - mine were fine, I changed from 1144s to RS15 on the same disks and they've been fine. Link to comment Share on other sites More sharing options...
caterhamnut Posted August 17, 2006 Author Share Posted August 17, 2006 - yep, just ordered some RS15's from Monmouth - said the same - just clean them well. Excellent friendly advice (John F wasn't there but his collegue was equally helpful) - should arrive tomorrow 😬 I currently have the greenstuff pads that came with the J Whiting Alcon brakes - I think I need to change them now - was loath to do so when they were new - thought I would at least build up a knowledge of them. Now I want to stop! Interested in Alex W's comments though - these have done many thousands of miles, and quite a few track days, and not even half worn, which might confirm that the compounds do indeed change from time to time...? I have left the rears for now - we currently have some 1177's in the rears which were lying around at rebuild time - obviously these are quite aggressive and have been locking up first, but I thought I would see how they perform in conjunction with the RS15's before changing them (maybe to RS14's) - not least because I don't have any bias adjustment (yet ) - thanks for the help guys! www.mycaterham.com here Videos here 96,000 miles -1st 1.6k Supersport, '95 Motor Show car Link to comment Share on other sites More sharing options...
stephen grant Posted August 17, 2006 Share Posted August 17, 2006 Angus - one thing to note with the RS-15's is the bedding in process, which is something like brake from 90mph->30mph 3 times in rapid succession. Obviously give them a few test runs first to make sure your setup isn't massively unbalanced (or leaking) for any reason before you go for the banzai run. I spent about half an hour just driving around getting loads of heat into them. They did squeak horribly for a short while (see Myles post), but they got over it within about an hour of hard use and now they don't squeak at all, even without the shims. stephen Link to comment Share on other sites More sharing options...

A10ROX Posted August 17, 2006 Share Posted August 17, 2006 recently put pagids in the front any feedback on the comment (I was told by someone I have some respect for!) ... 'be very careful with pagid front and back as the balance of the braking can be unsettled, particularly locking the rears.. only use pagid front and rear if you also have a brake balance bar' 🤔 A10ROX:OK, its an R500 without the magnesium bits sump etc and only 205bhp!

BOATBUOY Posted August 17, 2006 Share Posted August 17, 2006 What do these pads cost and how do they compare to the green stuff ones? My thoughts on green stuff is that they;'re fine when on track days running hot but once cool they don't have much bite and can glaze over quickly. Does anyone else find the same? Link to comment Share on other sites More sharing options...
caterhamnut Posted August 17, 2006 Author Share Posted August 17, 2006 For the Alcon brakes I have the cost was about £115 for the front axle. The potential for rears locking is why I have not (yet!) gone for the RS14s at the rear, as I don't have a bias valve. I think that comment is pretty accurate from what I know/have heard A10... www.mycaterham.com here Videos here 96,000 miles -1st 1.6k Supersport, '95 Motor Show car Link to comment Share on other sites More sharing options...
caterhamnut Posted August 17, 2006 Author Share Posted August 17, 2006 BB - I'll let you know how they compare! My greenstuff have been fine, but just a bit 'soft' and lacking in initial bite. It will be easier to compare once pagids are fitted, as praise for these tends to be universal. www.mycaterham.com here Videos here 96,000 miles -1st 1.6k Supersport, '95 Motor Show car Link to comment Share on other sites More sharing options...
Jason Plato Posted August 18, 2006 Share Posted August 18, 2006 Common problem with the std Caterham brakes is the rearward balance(I dont know how Caterham have gotten away with it after all these years using the sierra rear calipers). If you then install pads with greater "bite" then you will still have this problem. The trick is to balance the brake distribution front / rear with either different pads - as Angus is doing or fit a brake reduction valve to the rear circuit or install uprated front calipers ( and rear if you can) which will alter he balance and alow you to run a combination such as RS15 front and RS14 rear as I do with with uprated Caterham/ AP "race" brakes all round .

stephen grant Posted August 18, 2006 Share Posted August 18, 2006 On a track day last weekend the balance of mine felt ok with RS-15 on the front and something rather less ritzy (I suspect Mintex pads) on the rear, standard calipers all round. I certainly don't want any more rear bias, so I think i'll leave the RS14 rears in the box for the time being... By the way; what's involved with fitting a bias valve? I mean, how much replumbing of the brake lines is involved. Despite having an ex-race car, mine curiously doesn't have a bias valve. stephen Edited by - stephen grant on 18 Aug 2006 08:58:59 Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted August 18, 2006 Share Posted August 18, 2006 RS14's all round. AP 4 pots front, standard rears, big heavy engine in the front, big heavy Chinaman in the back. No brake bias valve, uprated master cylinder. Fronts lock first quite easily. Edited by - Alex Wong on 18 Aug 2006 09:21:00 Link to comment Share on other sites More sharing options...
andy couchman Posted August 18, 2006 Share Posted August 18, 2006 So what 'size' pads are in the Alcon 4 pots (useful for comparing prices and for other makes of pad). Andy Link to comment Share on other sites More sharing options...
