mantaboy89 Posted December 18, 2012 Share Posted December 18, 2012 changing the front brakes on my car and not sure what to go for? Was looking at ebc discs with green stuff pads but not sure if these will have enough stopping power. Are the older twin piston calipers better than the later sliding calipers? if anyone has any ideas or anything for sale that maybe suitable please let me know. thanks josh Quote Link to comment Share on other sites More sharing options...
monzta Posted December 18, 2012 Share Posted December 18, 2012 (edited) You need to go for vented discs. Discs and calipers are freely available from Rekord E2 2,2i (you may need to find them on German ebay). This is a direct fit bolt on conversion that will give you a major advantage in stopping power. Going for solid discs no matter what disc and pad you use is a bad idea if the goal is to upgrade you brakes. Another alternative that is easier to come by in the UK are Carlton GSi front disc brakes and calipers. Theese will require some machining to fit though and they are also quite large. 288mm or 296mm diameter so anything less of 15" wheels is a no-no. Also a very cheap and extremly effective upgrade. For this to work you will need to shim 4mm (2 mm off inside of mounting surface on disc, and 2mm on mounting surface of the hub). You will also need redrilling the disc to mount it on the hub (pcd 4x90 mm on the mounting bolts on the hub if i remember correctly (please check this) ) apart from that, its plug n´ play and massive massive brakes for a fraction of the cost of EBC discs and pads.

spiney_norman Posted December 19, 2012 Share Posted December 19, 2012 I'd go with Monzta on this one mate, I had the Carlton/Rekord 2.2 vented setup on the front of that orange Cav saloon, worked brilliantly. A lot less hassle than getting Carlton GSI discs to fit too. Did you get round to doing the 2.2 conversion on your hatch in the end? Quote Link to comment Share on other sites More sharing options...
monzta Posted December 19, 2012 Share Posted December 19, 2012 The major difference in the swap to vented discs is that the brakes won´t fade when stressing them. Solid brakes will begin to fade when they get hot, and as vented discs are faster to cool down again, they are quickly ready for the next abuse This was the biggest change i noticed on my first vented disc converted Manta. So i have been going for that almost every time i had a Manta as a very good and cheap upgrade. Quote Link to comment Share on other sites More sharing options...
bris jas Posted December 19, 2012 Share Posted December 19, 2012 Vented is the way to go, i have a set up off a 2.2 carlton that i don't need any more, disc's with hubs and calipers that came off my Manta B if your interested pm me Quote Link to comment Share on other sites More sharing options...
mantaboy89 Posted December 19, 2012 Author Share Posted December 19, 2012 Putting the 2.2 in my gte now, sports exhaust, cam and twin 45's or megasquirt, got a 400 kit for her too, the hatch getting the diesel treatment once the gte is complete. Prob beemer engine and box. Quote Link to comment Share on other sites More sharing options...
mantasrme Posted December 19, 2012 Share Posted December 19, 2012 If you're going for decent power then apart from vented brakes i would also recommend bigger discs and larger pads to get more braking power. The 2.2 setup isn't much of a power improvement in the braking effect but does resisit fade from overheating. I like the audi disc/astra 16v caliper setup with the right pads. You not only get a larger vented disc (256mm) and a modern caliper design, you also get a pad that is about twice the surface area of the 2.2/manta. So more leverage (bigger disc) better power delivery (reliable caliper that doesn't seize) and more friction (larger pad area) Or for a bit bigger early calibra turbo/cav 4x4 calipers and rwd cossie discs are 284mm Quote Link to comment Share on other sites More sharing options...
Kevin Abbott Posted December 19, 2012 Share Posted December 19, 2012 Or for a bit bigger early calibra turbo/cav 4x4 calipers and rwd cossie discs are 284mm As above, don't put tiny 250 mm disc on. What's the point. Only do the conversion once. Mickappy does a kit ( I think) to put 288 mm discs and then cally t or v6 callipers fit straight on.

mantaboy89 Posted December 20, 2012 Author Share Posted December 20, 2012 Would like to go bigger but what sort of price am i looking at then, what audi discs are needed? And also how available are the bits cuz i wanna get the car ready as soon as possible. Thanks for all the help Quote Link to comment Share on other sites More sharing options...
Retro Power Posted December 21, 2012 Share Posted December 21, 2012 all the bits mentioned above are very easily available. I would go with the setup that mantasrme suggests, with the audi discs and cavalier/astra/calibra 2.0 calipers. Its all off the shelf stuff, and with mintex 1144 pads in the calipers you'll find you have plenty enough stopping power. As an alternative, you can also use rekord/carlton vented discs with those calipers, but you get a bit of pad overhang. Still work a treat though, used that setup on my 200hp 16v manta way back in 1996 when I was younger and drove it like it was stolen and they never faded or gave any trouble at all!

opelman Posted December 21, 2012 Share Posted December 21, 2012 I second that. I use the audi discs with EBC yellowstuff for trackdays, they are more than adequate, the only addition I would suggest it to buy grooved discs as I did, this eliminates over temperature as the grooves will vent pad gasses, plain discs don't.

mantaboy89 Posted December 21, 2012 Author Share Posted December 21, 2012 What Audi discs do i need. Are the calipers twon pots and what machine work needs to be done. Do the calipers bolt straight on? Quote Link to comment Share on other sites More sharing options...
opelman Posted December 21, 2012 Share Posted December 21, 2012 I have a pair of the audi discs with all the machining already done, ie. centre bore opened out to fit manta hub and the 4 holes redrilled for the bolts. They are vented 256 mm plain discs and have hardly been used, they have been in the garage and do exhibit some light superficial surface corrosion that would soon dissapear in use. You would also require astra GTE Mk 2 calipers, these will bolt straight on with no modifications required. Standard Manta GTE hoses will fit. PM me if you are interested in the discs, cheers Quote Link to comment Share on other sites More sharing options...
Shug Posted December 21, 2012 Share Posted December 21, 2012 Calipers were fitted to a few different models. I had ones from a mk3 cavalier (Still do somewhere), but they were old (could possibly do with reconditioning) so I got some reconditioned early 1.8 vectra calipers.

tony g Posted December 31, 2012 Share Posted December 31, 2012 Does all of the above apply to A series too?ie caliper bolt spacing? Looking to upgrade one of mine soon Cheers Tony Quote Link to comment Share on other sites More sharing options...
Shug Posted December 31, 2012 Share Posted December 31, 2012 Yup. If you are using 13" wheels, check they will fit over. rostyles won't. ATS does depending on offset, and might need wheel spacers. Quote Link to comment Share on other sites More sharing options...
doveyte2800 Posted December 31, 2012 Share Posted December 31, 2012 we are using 2.2 carlton vented discs with kadett c calipers on our A. We run with 13" revolutions 0 offset and these are very close to the inside rims. regards Ian Quote Link to comment Share on other sites More sharing options...
