Slipper man Posted December 1, 2003 Share Posted December 1, 2003 My R500 has always disappointed me with the feel of its brakes. They are OK, but not as firm as I would like, and after they have been standing following a track session, they are very soft indeed, until they have been used a bit. I tried a race master cylinder (helped a little) flushed the system with new higher spec brake fluid, and bleed the brakes after every track day. They still don't feel as good as a friends' 1998 superlight. I can't think what the problem is. Any ideas? Link to comment Share on other sites More sharing options...

Luke Beaumont Posted December 1, 2003 Share Posted December 1, 2003 Sounds like a pad issue to me if they're going off after a thrash, which might also explain the pedal feel (depending on ones criteria for 'soft'). Link to comment Share on other sites More sharing options...
Rob Walker Posted December 1, 2003 Share Posted December 1, 2003 Keith, This problem plagued me for four years and I have taken advise from everyone in the trade. I am not going to go through all the mods that I tried but advise you to throw away those nasty Seirra rear calipers and fit the uprated brakes along with a set of pagid rs14 pads all round and some high spec brake fluid . You won`t regret it. Rob Link to comment Share on other sites More sharing options...
Slipper man Posted December 1, 2003 Author Share Posted December 1, 2003 Rob Do the uprated rear calipers have a handbrake function? where do I get them from? Keith Link to comment Share on other sites More sharing options...
Powderpuff Posted December 2, 2003 Share Posted December 2, 2003 I think uprated brakes with handbrake are a normal Caterham part ...in fact I think you can even get them from Demon Tweeks Link to comment Share on other sites More sharing options...
Rob Walker Posted December 2, 2003 Share Posted December 2, 2003 Keith, The uprated rear brake kit comes with, tiny handbrake calipers that are mounted off the De Dion ear and work independant of the Two pot AP main rear calipers. The Kit is a pukka Caterham kit number MB02R. and costs £500 plus vat. The kit consists of two De Dion ears which you will have to specify what camber you want .25 for slicks & ACB and 2Degrees for radials, two uprated hub carriers and bearings, two uprated discs, two AP 2 pot calipers, two Air brake spot handrake calipers, plus all fixings and goodridge hoses. A set of standard road pads. I would advise you to get a credit on these and buy some Pagid RS 14 instead which will be more suitable for your use. Performance braking in Monmouth can supply these 01600 713117. IMO the up rated rear brake kit is a bit of a bargin. Rob Link to comment Share on other sites More sharing options...
Rob Walker Posted December 2, 2003 Share Posted December 2, 2003 If you run with the watts linkage the ends of the flexible goodridge hoses will have to be modified to clear the rear facing radius arms. I used extended 45 degree offset banjo fittings on a friends Superlight R. You would be wise also to fit an adjustable brake proportioning valve into the rear circuit whilst you have it all drained of fluid. Link to comment Share on other sites More sharing options...
Jason Plato Posted December 2, 2003 Share Posted December 2, 2003 I thought I had good brakes untill I tried Robs new uprated rear system with Pagids ......... they were awsome ( a word I hate but is true in this instance ) Lotus 7 Club Speed Champion 2003 South Wales Area Organiser C7 TOP Link to comment Share on other sites More sharing options...
rgrigsby Posted December 2, 2003 Share Posted December 2, 2003 Agree with the uprated brakes suggestions, at the same time a fluid change to something like AP600 is definetly worth doing it can make a huge difference.
