Irrelevant Posted March 10, 2008 Share Posted March 10, 2008 naddy: 'Blues' are the rear pads Caterham supply for use on cars with big front brakes. They are standard Sierra pads of some kind or another (XR4i IIRC) and have a blue spot on them - hence the name. Link to comment Share on other sites More sharing options...
Stuart Faulds Posted March 10, 2008 Share Posted March 10, 2008 'Blues' to me would suggest a pagid RS4-2 - a fast road pad. Link to comment Share on other sites More sharing options...

Shad Posted March 11, 2008 Author Share Posted March 11, 2008 So far I've found the balance better than with the standard pads. At higher speed the fronts will lock first, at slower speeds the rears seem to lock first. With the standard pads I could never lock the fronts... the rears would always lock so I'd have to get off the pedal slightly. I'll see how I get on with the setup at Silverstone on Monday Link to comment Share on other sites More sharing options...
Mike Oxbiggar Posted March 11, 2008 Share Posted March 11, 2008 Does anyone find their RS15s generate a lot of brake dust?? Yep! ☹️ Wheels are filthy most of the time after a half-decent run...

Banjo Posted March 13, 2008 Share Posted March 13, 2008 Seems RS15 greys on the front and RS4-2 on the rears might be the solution, because if RS14s lock up the rears that is not good. Anyone tried this combination ? 'Cos youth a mask but it don't last, live it long and live it fast Link to comment Share on other sites More sharing options...

Rob Walker Posted March 13, 2008 Share Posted March 13, 2008 Most people that run competition brake pads run with a brake limiting valve in the rear circuit. This allows the rear braking effort to be adjusted to give the required front rear balance to suit all conditions. In my own experience running with uprated brakes all round it is not possible to work the front brakes enough on the road to keep aggressive linings such as the RS15 working within its operating temperature and as a result the pads glaze up. I would not fit anything above RS14 to my car in future. Link to comment Share on other sites More sharing options...
Banjo Posted March 13, 2008 Share Posted March 13, 2008 Thanks Rob - I should of course said I meant for track and race use, not road where I agree with you. 'Cos youth a mask but it don't last, live it long and live it fast Link to comment Share on other sites More sharing options...
Shad Posted March 13, 2008 Author Share Posted March 13, 2008 So far (and admitidly I've only done bedding in miles plus a little more) performance when cold is comparable to the performance I had from standard pads all round. Just my 2p Link to comment Share on other sites More sharing options...
MarchHare2008 Posted March 13, 2008 Share Posted March 13, 2008 Stuart, I can recommend cheese for the front pads and chocolate for the rear. I think you'll find this is an ideal combo for Roadsport A. Do you have any testing dates planned? Link to comment Share on other sites More sharing options...
Rob Walker Posted March 13, 2008 Share Posted March 13, 2008 Shad sorry to say that if your RS15 `s feel like standard road pads when cold then they are not bedded in correctly or are already glazed. The RS15 is a very high coefficient of friction pad .54 when cold rising to .62 when hot @600C no standard road pad delivers this type of performance and as such they should bite like nothing you have ever experienced when cold then the friction level increases as they get hot unlike a road pad which may fade when hot. Chalk and cheese. Link to comment Share on other sites More sharing options...
Shad Posted March 13, 2008 Author Share Posted March 13, 2008 Fair point Rob. I don't brake very hard when they're cold because I know they won't be up to temp, so it might not be a very fair comparison? Either way I'm happy with the pads so far, they have solved my problems. I might look into bias adjustment in the future One thing that's not helping me at the moment is a lot of pad knock-back from a knackered front wheel bearing, so my pedal is still longer and not as consistent as I'd like, so the confidence isn't quite there yet...

Banjo Posted March 13, 2008 Share Posted March 13, 2008 Mark-spotted! I tried the cheese fronts at the beginning of last season but switched to dairy milk midway. Needless to say I couldnt tell the difference and have decided to stick with my existing set up of porridge fronts and jellied eels rears! Im at Croft on Sunday and might do Brands on April 16th, otherwise not till the testing on Friday before race weekend. And to think I might get some useful contributions here!

MarchHare2008 Posted March 13, 2008 Share Posted March 13, 2008 I'd like to do Croft before the test day, especially as we only get about two and a half minutes track time on the Friday but it's just too far for me. I'm down for Brands on the 18th April and Cadwell on the 4th. I'm hoping to do Silverstone on Sunday too but the forecast looks ****e! Good luck with the preparations, see you soon.

GTD Posted March 14, 2008 Share Posted March 14, 2008 On the same advice from John, I have gone down the RS15/14 route on my car - looking forward to trying it out on the roads on Monday if it passed its MoT whilst I've been away this week! The Goodwood sprints will tell me what the braking is like from cold! Warning - no Caterham content here Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted March 14, 2008 Support Team Share Posted March 14, 2008 I've got RS15s fitted to the front (AP big brakes) and I am about to fit the RS14s I've had in the garage for over a year to the rear (using standard Caterham rears at the moment). I am a bit concerned that this will end up overbraking the rear (no brake limiting valve fitted). Rob Walker - is there anyway to "de-glaze" the front pads as I am sure they are not giving the optimum performance at the moment. I bought the pads for sprinting and track day performance but I think that as I also do a lot of road miles that these are not really suitable for me. Any thoughts?

Mark Durrant Posted March 14, 2008 Share Posted March 14, 2008 Shaun I have RS15's on the front, RS14's on the back with standard rear calipers and a standard master cylinder and the balance works for me . It might be worth dropping Pagid an email to see what they recommend on how to deglaze their pads info@bremsentechnik.de. Mine are OK as I do not use them round paddock at Curborough Mark D Comp Sec Link to comment Share on other sites More sharing options...
david nelson Posted March 14, 2008 Share Posted March 14, 2008 Shaun Will see you at the sprint day but I sold my rs14 rears as the balance did not work on my car. If you have seen any of the 2006 sprint dvd my car goes all over the place under braking. I change back to the standard rear pads and had no hairy braking events in 2007.

Support Team Shaun_E Posted March 14, 2008 Support Team Share Posted March 14, 2008 Mark and David - thanks. Looks like people have had different experiences but I'll chat with you both at Race Retro and the Curborough sprint intro day. I'll email Pagid and see what they say.

Rob Walker Posted March 14, 2008 Share Posted March 14, 2008 Shaun, You remove the pads , make note of each pads location for refitting and rub them on some 60 grade sand paper that is on a flat surface. You are trying to remove about 0.5mm of the friction material. Then you must clean any of the abrasive grit out of the face of the pad with an airline or carbon tet brake cleaner and a soft cloth. re-fit the pads and you have to then go through the pad break in proceedure once again basically 80 mph down to 50 mph braking as hard as possible about 5 times. At the end of that exercise the brakes should almost pull you eyes out of their sockets under braking . Best done before a track day or event or they will just glaze up again pottering around on our crowded roads. Rob Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted March 14, 2008 Support Team Share Posted March 14, 2008 Thanks Rob - I'll give it a go. When I orginally fitted them I found a deserted road on the trading estate for the bedding in! It's not easy to find a suitable empty road around Slough.

Martin S. Posted March 14, 2008 Share Posted March 14, 2008 Shaun, just set your alarm to 3am and take it out then 😬 I will be fitting RS15's to my standard front calipers over the weekend so will post my observations.
