captain chaos Posted June 1, 2002 Share Posted June 1, 2002 Run green stuff pads on the road or Mintex1144 and red stuff for track days. I've got big brakes all around but I can't compare difference between our two set-ups because I've always had them. Link to comment Share on other sites More sharing options...
scooby dooby doo Posted June 1, 2002 Share Posted June 1, 2002 when i did exactly what you're doing I found a HUGE improvemnt. the peddle is much firmer but also much... nicer somehow. I reckon its the best upgrade i ever did. I'll be going to big rear brakes as well soon... Dave Hooper - North London dmch2@lineone.net Link to comment Share on other sites More sharing options...
deeps Posted June 1, 2002 Share Posted June 1, 2002 I`ve got big brakes all round on mine with the standard master cylinder and they are brilliant. MOT time can be a drag, with the weedy little handbrake calipers, but it never fails. I believe caterham sourced the hanbrake calipers from a go-kart, but couldn`t swear to it. The pedal feel is the best I`ve felt in a Seven and would have the big back brakes for that alone.

Miraz Posted June 1, 2002 Share Posted June 1, 2002 Have to agree with Deeps....the big rear brakes do make a huge difference, both to the pedal feel and the ability to shed speed ridiculously quickly. As for pads...usual religious war will probably follow, there are lots of comments in the archives though. I'm running Pagid RS14 at the moment all round, and am very happy with them, both on road and track - also there appears to be minimal wear on them after 2,500 miles including two track days - yesterday's session was very heavy on the brakes.

agbucks Posted June 1, 2002 Share Posted June 1, 2002 re standard rear calipers, does anyone have the mintex part number for the higher spec pads? Link to comment Share on other sites More sharing options...
F355GTS Posted June 1, 2002 Share Posted June 1, 2002 The part number for std rear pads is MDB1287 this refers to the pad pattern ie the shape and size you will still need to specify the material ie 1144 or 1155 etc Mark Link to comment Share on other sites More sharing options...
Peter Carmichael Posted June 1, 2002 Share Posted June 1, 2002 The uprated master cylinder has a bigger bore than the standard one, so it moves less, but makes the pedal pressure higher. This can give the impression of having no brakes. The way to fix this is to run a higher friction pad - Pagids being the most expensive and best. I ran the standard master cylinder with big brakes all round and this was an excellent combination. I wouldn't go near green stuff if I ever used the car on a track.

martinwhitcher Posted June 3, 2002 Share Posted June 3, 2002 does the superlight come with big brakes (rear) as standard (original s/l not R300 wanabe s/lsmile.gif) Martin Link to comment Share on other sites More sharing options...
EFA Posted June 4, 2002 Share Posted June 4, 2002 No production Seven except the JPE. VX racers and SLR racers came with anything but std rear brakes. The uprated rear caliper upgrade was deleted some time ago from road cars as the handbrake functionality was so questionable. An extra big "big rear brake kit" exists for the SLR racer for around £900 - no handbrake though!

Davey Bee Posted June 4, 2002 Author Share Posted June 4, 2002 Peter why not green stuff on track I thought they was the best compromise. Am I about to start a war!! Buzzin' Beeid=red> cool.gif cool.gifcool.gif Link to comment Share on other sites More sharing options...
Peter Carmichael Posted June 4, 2002 Share Posted June 4, 2002 Green stuff have been reported time and again to turn to dust under track usage (especially at the rear) - generally considered to be inappropriate and sh1te. FWIW Mintex 1144 had problems in my rear calipers so I went to Mintex 1155 all round which worked very well in big brakes. My recent change to race master cylinder has been accompanied with a change to higher friction Pagid pads, so the bite and pedal weight are very similar to the Mintex set up, but the pedal travel is less.

CHRIS CLARK Posted June 4, 2002 Share Posted June 4, 2002 Even EBC say try Red Stuff for track days! They say these work on the road but take a bit longer to reach temp. Not a problem on a track day. IIRC the temp changeover point from Green to Red is around the 550* mark. Link to comment Share on other sites More sharing options...
F355GTS Posted June 4, 2002 Share Posted June 4, 2002 Davey I'm running Uprated Master Cylinder 4 Pot AP/ Caterham fronts Standard Rears Mintex 1155 Pads Brakes are awesome for both road and trackdays, wear is good on the pads, done 3 trackdays now and 2,000 road miles with approx 25% wear Mark Link to comment Share on other sites More sharing options...
Davey Bee Posted June 7, 2002 Author Share Posted June 7, 2002 Thanks guys, looks like I will give the Mintex a try. Buzzin' Beeid=red> cool.gif cool.gifcool.gif Link to comment Share on other sites More sharing options...
agbucks Posted June 7, 2002 Share Posted June 7, 2002 if you looking for a competitive price on mintex pads and some very helpful advice, try questmead on 08707 450584. i just bought a full set of m1144 pads from them. Link to comment Share on other sites More sharing options...
Violet Elizabeth Posted June 7, 2002 Share Posted June 7, 2002 I am running greenstuff at the front, do I need to change these over before going to oulton in a months time ? Or just wait and see on the day, armed with something else ? Link to comment Share on other sites More sharing options...
Peter Carmichael Posted June 7, 2002 Share Posted June 7, 2002 It is the rears that give the most problems with heat, but take advice from people who have run green stuff on a car with your power and your front brake set up.

Violet Elizabeth Posted June 7, 2002 Share Posted June 7, 2002 1700SS. Live axle. Standard front brakes apart from the greenstuff. Only changed as had calipers replaced by non-caterham brake people, who put some nasty lockheed pads in. EBC were easier to get hold of than Mintex.

rgrigsby Posted June 7, 2002 Share Posted June 7, 2002 Depends on what tyres your running as well, greenstuff will be ok on normal road tyres, if you're on yoko 032r's or something similar then they will overheat but should last a few track days. If you're on ACB10's then they probably won't last the day!! I'm running a 1700SS with ACB10's and using Redstuff pads, they are overheating (lots of dust on the wheels) but last 3-4 track days on the front and a 5/6 on the rear.

JP Posted June 7, 2002 Share Posted June 7, 2002 My brakes are std except for 1144's and uprated master cylinder. They have a great feel and bite especially when warm. However they can get a bit vague when very hot - has anyone tried grooved and/or drilled std discs and would these help? (1.6KSS) James Link to comment Share on other sites More sharing options...
