caterhamnut Posted March 22, 2004 Share Posted March 22, 2004 Great fun at Hullavington on Friday - car went great, but braking heavily into corners (for sideways fun!) the rears would lock up very easily. I know this is a common Caterham problem - but what can I do to stop/reduce it. Brakes are 'standard' all round. ta NEW Nurburgring Pictures posted here 55,000miles in 2.5 years Link to comment Share on other sites More sharing options...
Irrelevant Posted March 22, 2004 Share Posted March 22, 2004 If I'm not mistaken, I think the answer is a brake proportioning valve. IIRC, they're better than bias adjustments as they only reduce the rear wheel's braking effect at high pressure so the back brakes work as normal at lower pressures.

Pelico Posted March 22, 2004 Share Posted March 22, 2004 Angus, To try to help this 'cheaply *thumbup*' I have uprated the pads on my front and left a set of 'Uniparts' on the rear. Still bedding them in to have a firm view on the success, but already it does seem to pull up quickly. I did plan to go for Mintex 1144s for the front, but when I called Dave K at Demon Tweeks he had sold out and he suggested some Ferodo 3466 instead. Never heard of them before and nothing on Blachat about them, but they were black and fitted the right hole 😬.

julians Posted March 22, 2004 Share Posted March 22, 2004 I have the same problem, so I went for 1144's in the front and halfords cheap crap own brand in the back, unfortunately it made no difference to the balance. I'm slowly resigning myself to the fact that I'm going to have to buy the big brakes, however I am going to have one last shot at bleeding them (again), but this time I'm going to jack the front of the car up in an attempt to shift any last remaining air.

tom7 Posted March 22, 2004 Share Posted March 22, 2004 I have standard brakes and had the same problem. For a simple solution, I removed the 'centre third' of pad material from each rear pad. No detrimental effect on overall braking but now is balanced better. This technique is an old tried and trusted road-rally solution. Tom Link to comment Share on other sites More sharing options...
Area Representative Paul Richards Posted March 22, 2004 Area Representative Share Posted March 22, 2004 I had the same problem and have recently fitted Mintex M1144 pads to the front. Not had a chance to try them fully yet, but seems to be a reasonable improvement. Did the MOT brake test since fitting and pedal effort to get fronts to work was a lot less than last year. Suggest you give them a try. At £30ish they're cheaper than bias valves and big brakes. Paul Richards Joint AO - L.A.D.S.

Jason Plato Posted March 22, 2004 Share Posted March 22, 2004 Try pagids at the front . or fit a valve in the rear circuit . Link to comment Share on other sites More sharing options...
caterhamnut Posted March 22, 2004 Author Share Posted March 22, 2004 cheers guys - so the simplified answer is to uprate the front brakes 'to match' - be it through better pads or better calipers etc. I know the pagids are expensive - but what is the wear rate on these like. Any opinions on best uprated calipers - for example Caterhams own, or those supplied by James Whiting? PS - Dave - thanks for all your advice before - excellent!

Mark Durrant Posted March 22, 2004 Share Posted March 22, 2004 Angus Give James Whiting a call. IIRC correctly he recommends Pagids on the front and standard Catewrham pads on the rears. Failing that fit a brake bias valve. Mark D Su77on Se7ens Making plans for the 2004 Sprint Season Link to comment Share on other sites More sharing options...
julians Posted March 22, 2004 Share Posted March 22, 2004 How do you remove pad material? use an angle grinder? Edited by - julians on 22 Mar 2004 14:24:56 Link to comment Share on other sites More sharing options...
Jason Plato Posted March 22, 2004 Share Posted March 22, 2004 Get your Pagids from Performance Braking in Monmouth - these will work great in the std calipers with some decenbt fluid like SRF . The pagids wear very slowly . So this wont be a problem Angus . They are expensive in the first instance , but they are worth it . Glad the tweeks worked ;-)) See you saturday .....

caterhamnut Posted March 22, 2004 Author Share Posted March 22, 2004 Really looking forward to it Dave Do Monmouth do mail order - and do you have a contact number? NEW Nurburgring Pictures posted here 55,000miles in 2.5 years Link to comment Share on other sites More sharing options...
tom7 Posted March 22, 2004 Share Posted March 22, 2004 You can remove pad material with a hacksaw (to define area) and a sharp chisel. Link to comment Share on other sites More sharing options...
dino ferrana Posted March 22, 2004 Share Posted March 22, 2004 Never had any experience of any other uprated Caterham brake systems only the AP Racing Caterham one. I think the fact that the same braking system is used in the R500 to brake the 0-100-0 record says it all for me! Link to comment Share on other sites More sharing options...
Asklepios Posted March 23, 2004 Share Posted March 23, 2004 I would endorse the advice on Pagids /Performance Braking. Additionally ,spend £10 per disc on new front (standard) discs. I bought james W`s Alcon ,and it really is a lovely set up. However, bang for buck is Pagid + disc. Link to comment Share on other sites More sharing options...
caterhamnut Posted March 23, 2004 Author Share Posted March 23, 2004 Where does one get new discs from for £10? NEW Nurburgring Pictures posted here 55,000miles in 2.5 years Link to comment Share on other sites More sharing options...
Mark Durrant Posted March 23, 2004 Share Posted March 23, 2004 Good question. I recently bought a pair of new discs from James Whiting and they were £32 + VAT. Mark D Su77on Se7ens Making plans for the 2004 Sprint Season Link to comment Share on other sites More sharing options...
